This data table reports the statewide monthly number of deaths that occurred in California regardless of the place of residence (by occurrence) and deaths to California residents (by residence). The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed will affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not take into account contributing causes of death.

California requires that all local governments (cities and counties) adequately plan to meet the housing needs of everyone in the community. California’s local governments meet this requirement by adopting housing plans as part of their “general plan”. General plans serve as the local government’s "blueprint" for how the city and/or county will grow and develop and include eight elements: land use, transportation, conservation, noise, open space, safety, environmental justice, and housing. The Housing Element Compliance Report provides current Housing Element Compliance Status. Additional information about Housing Elements can be found on HCD’s website here: https://www.hcd.ca.gov/planning-and-community-development/housing-elements.

This data table reports the statewide monthly number of deaths that occurred in California regardless of the place of residence (by occurrence) and deaths to California residents (by residence). The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed can affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not always take into account all conditions contributing to the death. Cause of death categories for years 1999 and later are based on tenth revision of International Classification of Diseases (ICD-10) codes. Comparable categories are provided for years 1979 through 1998 based on ninth revision (ICD-9) codes. For more information on the comparability of cause of death classification between ICD revisions see [Comparability of Cause-of-death Between ICD Revisions](https://www.cdc.gov/nchs/nvss/mortality/comparability_icd.htm).

Seasonal groundwater level reports provide information from selected water level measurements and are intended to portray the change in seasonal groundwater levels over specific time intervals. Each point shows the calculated difference between the measured groundwater levels from the selected time periods. The change in groundwater level is plotted on the map only if a measurement exists in both time periods at a well. These change values are derived from the DWR Periodic Groundwater Levels dataset that contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Most measurements are taken manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements. This service is under development in support of ongoing enhancements to CalGW Live. Once the format is finalized, the service will be hosted at https://gis.water.ca.gov/arcgis/rest/services/. DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data.

This dataset contains counts of deaths for California as a whole based on information entered on death certificates. Final counts are derived from static data and include out-of-state deaths to California residents, whereas provisional counts are derived from incomplete and dynamic data. Provisional counts are based on the records available when the data was retrieved and may not represent all deaths that occurred during the time period. Deaths involving injuries from external or environmental forces, such as accidents, homicide and suicide, often require additional investigation that tends to delay certification of the cause and manner of death. This can result in significant under-reporting of these deaths in provisional data. The final data tables include both deaths that occurred in California regardless of the place of residence (by occurrence) and deaths to California residents (by residence), whereas the provisional data table only includes deaths that occurred in California regardless of the place of residence (by occurrence). The data are reported as totals, as well as stratified by age, gender, race-ethnicity, and death place type. Deaths due to all causes (ALL) and selected underlying cause of death categories are provided. See temporal coverage for more information on which combinations are available for which years. The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed can affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not always take into account all conditions contributing to the death.

This dataset contains counts of deaths for California counties based on information entered on death certificates. Final counts are derived from static data and include out-of-state deaths to California residents, whereas provisional counts are derived from incomplete and dynamic data. Provisional counts are based on the records available when the data was retrieved and may not represent all deaths that occurred during the time period. Deaths involving injuries from external or environmental forces, such as accidents, homicide and suicide, often require additional investigation that tends to delay certification of the cause and manner of death. This can result in significant under-reporting of these deaths in provisional data. The final data tables include both deaths that occurred in each California county regardless of the place of residence (by occurrence) and deaths to residents of each California county (by residence), whereas the provisional data table only includes deaths that occurred in each county regardless of the place of residence (by occurrence). The data are reported as totals, as well as stratified by age, gender, race-ethnicity, and death place type. Deaths due to all causes (ALL) and selected underlying cause of death categories are provided. See temporal coverage for more information on which combinations are available for which years. The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed can affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not always take into account all conditions contributing to the death.

This data table reports the monthly number of deaths that occurred in each California county regardless of the place of residence (by occurrence) and deaths to residents of each California county (by residence). The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed can affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not always take into account all conditions contributing to the death. Cause of death categories for years 1999 and later are based on tenth revision of International Classification of Diseases (ICD-10) codes. Comparable categories are provided for years 1979 through 1998 based on ninth revision (ICD-9) codes. For more information on the comparability of cause of death classification between ICD revisions see [Comparability of Cause-of-death Between ICD Revisions](https://www.cdc.gov/nchs/nvss/mortality/comparability_icd.htm).

This map includes change areas for city and county boundaries filed in accordance with Government Code 54900. The initial dataset was first published on October 20, 2021, and was based on the State Board of Equalization's tax rate area boundaries. As of April 1, 2024, the maintenance of this dataset is provided by the California Department of Tax and Fee Administration for the purpose of determining sales and use tax jurisdictions. The boundaries are continuously being revised when areas of conflict are discovered between the original boundary provided by the California State Board of Equalization and the boundary made publicly available by local, state, and federal government. Some differences may occur between actual recorded boundaries and the boundaries used for sales and use tax purposes. The boundaries in this map are representations of taxing jurisdictions and should not be used to determine precise city or county boundary line locations. The data is updated within 10 business days of the CDTFA receiving a copy of the Board of Equalization's acknowledgement letter. BOE_CityAnx Data Dictionary: COFILE = county number - assessment roll year - file number (see note*); CHANGE = affected city, unincorporated county, or boundary correction; EFFECTIVE = date the change was effective by resolution or ordinance (see note*); RECEIVED = date the change was received at the BOE; ACKNOWLEDGED = date the BOE accepted the filing for inclusion into the tax rate area system; NOTES = additional clarifying information about the action. *Note: A COFILE number ending in "000" is a boundary correction and the effective date used is the date the map was corrected. BOE_CityCounty Data Dictionary: COUNTY = county name; CITY = city name or unincorporated territory; COPRI = county number followed by the 3-digit city primary number used in the Board of Equalization's 6-digit tax rate area numbering system (for the purpose of this map, unincorporated areas are assigned 000 to indicate that the area is not within a city).

Suisun Marsh Salinity Control Gates Log as of 03/02/2026. This log of operations includes: flashboard installation and removal dates, when tidal operations were started and stopped, and notes any technical issues. This document is an Excel file that contains the data as a Table. The Table can be sorted or filtered, and can be read by scripting languages such as Python or R. The date and time are stored together in the DATETIME field. The GATE 1, GATE 2, and GATE 3 fields state whether each gate is operating in Tidal Mode, set to Open, or set to Closed. The ACTION field states what operational change has occurred. The timestamped records go back to May 5, 2018. If prior dates are needed, refer to the Historical (Archived) Suisun Marsh Salinity Control Gates Log PDF, which contains records going back to November 1, 1998. This document replaces the Archived version because the Archived version did not contain a timestamp for every record. For the records that did have a timestamp, the timestamps were placed in the REMARKS field. This issue, along with the document being a PDF file, created a problem for reading the data into time-series analysis software.

This dataset contains annual validated water loss audit reports submitted to the Department of Water Resources by California urban retail water suppliers, as required under Title 23, California Code of Regulations Section 638.5(c) (Regulation). California Water Code Section 10608.12(af) specifies that urban retail water suppliers are those water suppliers directly providing potable municipal water to more than 3,000 service connections or that supply more than 3,000 acre-feet per year at retail for municipal purposes. The Regulation mandates that urban retail water suppliers with multiple separate potable water systems submit a separate audit for each system, regardless of system size. The dataset includes individual water loss audits for all potable water systems owned by urban retail water suppliers, including reports from water suppliers newly classified as urban retail water suppliers. While all submissions are available at the WUEdata.ca.gov portal, this dataset provides a cleaned version with only the latest submissions (older submissions that were corrected are not included). Water system boundaries for the water system water loss data in this dataset may be available in the Water Board's DDW California Drinking Water System Area Boundaries (SABL) tool. The link to this tool can be found in Additional Resources as part of this dataset. Water loss audits evaluate real water losses (leaks) and apparent water losses (e.g. data errors, water theft) occurring in a potable water distribution system. Estimating the scale and cost of these losses allows utilities to identify opportunities for saving water and recovering revenue. California water loss audit submissions were reviewed by validators and submitted to DWR starting in 2016. The reviews followed the validation methodology detailed in Water Research Foundation Project 4639: Level 1 Water Audit Validation. Level 1 water audit validation aims to: * Identify and, where possible, correct inaccuracies in water audit data and application of methodology. * Evaluate and communicate the uncertainty inherent in water audit data. The data is provided "as is" (as submitted by the water systems). More information on this dataset can be found in the file "Data Source and Notes" available at the on the home page of this dataset.

Consistent with Health and Safety Code section 116530 and California Code of Regulations title 22 §64412, public water systems report the population served during a specified reporting period and the population type, which can be reported as either Residential (R), Non-Transient (N), Transient (T), or Wholesale (W). This table contains residential (R) population data for public water systems owned and operated by urban retail water suppliers. ["Residential"](https://www.waterboards.ca.gov/drinking_water/certlic/drinkingwater/documents/ear/ear-help-tips.pdf) refers to the number of persons who reside within the water system service area for more than half of the year. For each system, the R-population value represents the most recently reported and most contemporary value for the prior state fiscal year (July to June), as denoted in the FY_START_DATE and FY_END_DATE columns. Public Water System data, including population, can be viewed using [Drinking Water Watch](https://sdwis.waterboards.ca.gov/PDWW/). If the population values identified in this dataset need to be revised, please contact the appropriate State Water Resources Control Board’s Division of Drinking Water [district office](https://www.waterboards.ca.gov/drinking_water/programs/documents/ddwem/DDWdistrictofficesmap.pdf) and update accordingly. The Division of Drinking Water has documented the procedure to request population changes outside of the Electronic Annual Report [here](https://data.ca.gov/dataset/c69ac02b-adfb-459a-bc58-bf69a8b572d2/resource/0ba8a039-9459-4796-916d-179cf0da6173/download/guidance_changing-population-procedure.pdf).

California Department of Housing and Community Development
The Women, Infants and Children (WIC) Program is a federally-funded health and nutrition program that provides assistance to pregnant women, new mothers, infants and children under age five. WIC helps California families by providing food benefits to individual participants based on their nutritional need and risk assessment. The food benefits can be used to purchase healthy supplemental foods from about 4,000 WIC authorized vendor stores throughout the State. WIC also provides nutritional education, breastfeeding support, healthcare referrals and other community services. Participants must meet income guidelines and other criteria. Currently, 84 WIC agencies provide services monthly to approximately one million participants at over 500 sites in local communities throughout the State. Prior to June 2019, WIC issued paper food instruments (FIs) to individual participants for purchasing supplemental, nutritious foods. Beginning in June 2019, California WIC began transitioning to a new food delivery system, replacing the FI delivery system with the Electronic Benefit Transfer (EBT) system. California WIC completed this transition in March 2020. With the previous FI delivery system, participants were issued three or four paper FIs per month listing the foods that could be redeemed at authorized vendor stores. In order to take full advantage of their benefits in the FI delivery system, participants had to purchase all of the foods listed on a FI in a single transaction or lose that benefit. In contrast, in the EBT system a family’s benefits are combined and uploaded to one EBT card. Participants can use this card to purchase WIC foods as needed through the benefit expiry date without having to purchase foods that they don’t need yet and without risking losing their benefits. The data files provided contain monthly and annual redemption information from the FI delivery system and the EBT system by the county in which WIC participants redeemed their food benefits. Because FIs are issued and redeemed at the participant level, the FI redemption data are presented with aggregation at the participant level (e.g., participant category). However, because EBT redemptions only occur at the family level, EBT data can only be presented with aggregation at the family level. Therefore, we provide two types of aggregated data: 1. WIC Redemption by Vendor County by Participant Category contains the number of FIs redeemed, the dollar amount of FIs redeemed, and the count of unique individual participants, from 2010 to 2018. This data is no longer available beyond 2018 due to transitioning from the FI delivery system to the EBT system. 2. WIC Redemption by Vendor County with Family Counts contains data from before and after the EBT transition period (i.e., 2010 – present), and provides the count of unique families instead of participants. It comprises three parts: - Part A contains only FI redemption data from 2010 to 2018; - Part B contains both the FI redemption data and the EBT redemption data for the EBT transition period that occurred in 2019 and 2020; - Part C contains only EBT redemption data for 2021 and forward. The dollar amount of redemptions and the number of families redeeming benefits are expected to vary from month to month. Many of these monthly variations can be attributed to the number of days and holidays in a month. Additionally, in June 2021 the federal government approved a Cash Value Benefits (CVB) expansion, which resulted in a large increase in monthly EBT redemption amounts. The initial CVB expansion was implemented in California from June 2021 to September 2021 and provided $35 per month for all non-infant participants, increased from $9 - $11. The CVB expansion was subsequently extended several times. Effective October 1, 2023, CVB was set at new inflation-adjusted amounts where pregnant and postpartum individuals receive $47 per month, breastfeeding individuals receive $52 per month, individuals breastfeeding more than one infant receive $78 per month, and children ages 1-5 received $26 per month. To ensure WIC participant and vendor anonymity, the redemption data has been suppressed when number of WIC vendors were less than 3 or number of redeemed participants or families were less than 11. The suppressed cells are annotated as “–“.

2009 Hospital Emergency Department - External Cause of Injury/Morbidity Code Frequency
This data table reports the statewide annual number of deaths that occurred in California regardless of the place of residence (by occurrence) and deaths to California residents (by residence). The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed will affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not take into account contributing causes of death.

Wastewater discharges are regulated by the Water Board. Those regulated are generally required to submit Self-Monitoring Reports to the State or Regional Water Board. Some dischargers submit their reports through the electronic Self-Monitoring Report (eSMR) module of the California Integrated Water Quality System (CIWQS). Generally these are for discharges into surface waters regulated by an individual National Pollutant Discharge Elimination System (NPDES) permit, though other dischargers may be included in this dataset as well. This dataset are the monitoring results that have been submitted as data points after the submitters have been approved for electronic submittals (i.e. after the "all electronic date"). Note that this dataset does not include records where the sampling date falls outside of the years shown below. The excluded records include: records where the sampling date is missing, records where the sampling date is invalid (e.g., records with sampling dates in the future or unreasonably far in the past), and records for samples taken prior to year 2006. The excluded records represent approximately 0.1% of all records in the complete eSMR dataset.

This data table reports the statewide annual number of deaths that occurred in California regardless of the place of residence (by occurrence) and deaths to California residents (by residence). The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed can affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not always take into account all conditions contributing to the death. Cause of death categories for years 1999 and later are based on tenth revision of International Classification of Diseases (ICD-10) codes. Comparable categories are provided for years 1979 through 1998 based on ninth revision (ICD-9) codes.

The Department of Water Resources Telemetered Wells dataset contains information regarding wells within the DWR monitoring network that have telemetry equipment installed. The wells included in this dataset have been completed, a well completion report (WCR) has been submitted through the Online System for Well Completion Reports (OSWCR), and have been registered either through the California Statewide Groundwater Elevation Monitoring (CASGEM) Online System or the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM).
The DWR Groundwater Level Percentile Statistics are based on the USGS Groundwater Watch concept of comparing the most recent groundwater level measurement to historical measurements for the same month. For a well to be ranked, the most recent measurement must have occurred within the last 18 months, and measurements from at least 10 years must exist for that month. These statistics are derived from the DWR Periodic Groundwater Levels dataset that contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Most measurements are taken manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements. This service is under development as part of of ongoing enhancements to CalGW Live. Once the format is finalized, the service will be hosted at https://gis.water.ca.gov/arcgis/rest/services/. DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data.

This current document is an Excel file that contains the data as a Table. The Table can be sorted or filtered, and can be read by scripting languages such as Python or R. The date and time are stored together in the DATETIME field. The GATE 1, GATE 2, and GATE 3 fields state whether each gate is operating in Tidal Mode, set to Open, or set to Closed. The ACTION field states what operational change has occurred. The timestamped records go back to May 5, 2018. If prior dates are needed, refer to the Historical (Archived) Suisun Marsh Salinity Control Gates Log PDF, which contains records going back to November 1, 1998. This document replaces the Archived version because the Archived version did not contain a timestamp for every record. For the records that did have a timestamp, the timestamps were placed in the REMARKS field. This issue, along with the document being a PDF file, created a problem for reading the data into time-series analysis software.

The GeoPDNN (Geological Pseudolabel Deep Neural Network) is a semi-supervised machine learning tool that integrates point-based datasets - such as formation picks from lithologic well logs or individual AEM soundings- into plausible stratigraphic surfaces for a preliminary hydrostratigraphic model. File contains a preliminary description of the Data2HSM via GeoPDNN tool. Tool expected to be publicly available in Mid-late 2025.
__Note__: In these datasets, a person is defined as up to date if they have received at least one dose of an updated COVID-19 vaccine. The Centers for Disease Control and Prevention (CDC) recommends that certain groups, including adults ages 65 years and older, receive additional doses. On 6/16/2023 CDPH replaced the booster measures with a new “Up to Date” measure based on CDC’s new recommendations, replacing the primary series, boosted, and bivalent booster metrics The definition of “primary series complete” has not changed and is based on previous recommendations that CDC has since simplified. A person cannot complete their primary series with a single dose of an updated vaccine. Whereas the booster measures were calculated using the eligible population as the denominator, the new up to date measure uses the total estimated population. Please note that the rates for some groups may change since the up to date measure is calculated differently than the previous booster and bivalent measures. This data is from the same source as the Vaccine Progress Dashboard at https://covid19.ca.gov/vaccination-progress-data/ which summarizes vaccination data at the county level by county of residence. Where county of residence was not reported in a vaccination record, the county of provider that vaccinated the resident is included. This applies to less than 1% of vaccination records. The sum of county-level vaccinations does not equal statewide total vaccinations due to out-of-state residents vaccinated in California. These data do not include doses administered by the following federal agencies who received vaccine allocated directly from CDC: Indian Health Service, Veterans Health Administration, Department of Defense, and the Federal Bureau of Prisons. Totals for the Vaccine Progress Dashboard and this dataset may not match, as the Dashboard totals doses by Report Date and this dataset totals doses by Administration Date. Dose numbers may also change for a particular Administration Date as data is updated. Previous updates: * On March 3, 2023, with the release of HPI 3.0 in 2022, the previous equity scores have been updated to reflect more recent community survey information. This change represents an improvement to the way CDPH monitors health equity by using the latest and most accurate community data available. The HPI uses a collection of data sources and indicators to calculate a measure of community conditions ranging from the most to the least healthy based on economic, housing, and environmental measures. * Starting on July 13, 2022, the denominator for calculating vaccine coverage has been changed from age 5+ to all ages to reflect new vaccine eligibility criteria. Previously the denominator was changed from age 16+ to age 12+ on May 18, 2021, then changed from age 12+ to age 5+ on November 10, 2021, to reflect previous changes in vaccine eligibility criteria. The previous datasets based on age 16+ and age 5+ denominators have been uploaded as archived tables. * Starting on May 29, 2021 the methodology for calculating on-hand inventory in the shipped/delivered/on-hand dataset has changed. Please see the accompanying data dictionary for details. In addition, this dataset is now down to the ZIP code level.

(Webpage Under Development) The Department of Water Resources (DWR) provides Technical Support Services (TSS) to assist Groundwater Sustainability Agencies (GSAs) with the implementation of their Groundwater Sustainability Plans (GSPs) and other local entities to better understand groundwater conditions. These services support data collection, groundwater monitoring, and improved understanding of groundwater conditions to help advance sustainable groundwater management efforts across California. Through the TSS program, DWR has partnered with GSAs and other entities on projects across the state to drill and construct groundwater monitoring wells, install groundwater level recording and telemetry equipment, perform downhole camera and geophysical surveys, and collect and analyze groundwater for general chemistry. The data and reports generated from these efforts are publicly available to support ongoing groundwater management and planning. Additional information can be found on the [Assistance and Engagement webpage](https://water.ca.gov/Programs/Groundwater-Management/Assistance-and-Engagement "Assistance and Engagement webpage"). #Summary of Completed TSS Projects To date, DWR has completed TSS projects in **35 groundwater subbasins**, constructing **234 monitoring wells** at **92 sites** statewide. Each of these wells have been assigned a State Well Number (SWN), have had a Well Completion Report (WCR) submitted to DWRs Online System for Well Completion Reports (OSWCR), and have been registered either through the California Statewide Groundwater Elevation Monitoring (CASGEM) Online System or the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM). Groundwater level data from these wells are collected by the GSA or DWR and submitted to CASGEM and/or the MNM. These data can be viewed on the [Water Data Library (WDL)](https://wdl.water.ca.gov/waterdatalibrary/ "Water Data Library (WDL)"). WCRs for these wells can be found using the [Well Completion Report Map Application](https://dwr.maps.arcgis.com/apps/webappviewer/index.html?id=181078580a214c0986e2da28f8623b37 "Well Completion Report Map Application"). A summary table of completed TSS wells including their associated well name(s), site code(s), SWN(s), and WCR number(s), can be viewed and/or downloaded here: [DWR Completed TSS Wells](https://data.cnra.ca.gov/dataset/completed-tss-wells/resource/5263a74b-aae2-4040-9e69-7bf85b9ff120) An interactive GIS map containing a feature set of all completed TSS wells can be accessed here: [GIS Map of Completed TSS Wells](https://www.arcgis.com/apps/mapviewer/index.html?url=https://services.arcgis.com/aa38u6OgfNoCkTJ6/ArcGIS/rest/services/DWR_Technical_Support_Services_(TSS)_Wells/FeatureServer&source=sd “GIS Map of Completed TSS Wells”) The individual TSS well locations, associated borehole lithologic information, and groundwater level data can be viewed on the [SGMA Data Viewer](https://sgma.water.ca.gov/webgis/?appid=SGMADataViewer#gwlevels “SGMA Data Viewer”) by: 1.

DWR, in coordination with the State Water Resources Control Board, has developed an interactive dashboard, called the [Dry Domestic Well Susceptibility within Groundwater Basins Dashboard](https://storymaps.arcgis.com/stories/f2b252d15a0d4e49887ba94ac17cc4bb#ref-n-aoS5Sy) (Dry Well Susceptibility Dashboard), to identify areas within groundwater basins throughout the State that may be prone to water supply shortages due to domestic drinking water wells going dry. The dashboard identifies the density of "susceptible” domestic wells per square mile based on recent groundwater level measurements and modeled future depth to water. If the modeled future depth to water falls below the dry well depth of a domestic well, the well is labelled susceptible. The Dry Well Susceptibility Dashboard is housed on the California’s Groundwater Live web-based platform which contains the latest information and data on groundwater conditions across the State. The State, local agencies, and well owners can use this dashboard to anticipate where wells may be susceptible to inform drought preparedness decision-making and resource allocation. __If you are currently experiencing a dry domestic well, you can report that to DWR’s [Dry Well Reporting System](www.mydrywell.ca.gov) which will connect you with available local assistance.__ The query for domestic wells was based on DWR’s Online System for Well Completion Reports (OSWCR). Well uses that are specified on well completion reports have been grouped into domestic wells (See attribute 'B118WellUse'). The complete Well Completion Report Dataset is available at https://data.cnra.ca.gov/dataset/well-completion-reports. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements. This service is under development as part of ongoing enhancements to CalGW Live. Once the format is finalized, the service will be hosted at https://gis.water.ca.gov/arcgis/rest/services/. _DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data._ _This dashboard and the underlying analysis provide a density map of domestic wells that are susceptible to going dry if recent groundwater trends continue. The map can be used to evaluate the relative density distribution within groundwater basins. However, the map should not be used to estimate the absolute number of domestic wells that are susceptible to going dry for any area or groundwater level scenario. While the applied groundwater level scenario is based on best available datasets, the scenario is hypothetical, and is chosen to resolve regional differences in the density of domestic wells that are susceptible to going dry. Available groundwater level data are interpolated and projected to domestic wells locations. To achieve near statewide coverage for this analysis, groundwater level measurements are projected up to 10 miles in areas where no local monitoring exists. Filling these groundwater level data gaps with new monitoring stations will improve the reliability of the Dry Well Susceptibility Analysis. The applied model for the depth at which a domestic well is susceptible to going dry is simplified and uncalibrated and is not intended to represent any specific well failure mode. Future calibration of this model, and consideration of well construction details will improve the reliability of the Dry Well Susceptibility Analysis._

Links to spatial data resources for the groundwater elevation monitoring stations (wells) maintained in the California Department of Water Resources’ (hereafter the Department) Enterprise Water Management database. Individual station information comes from a wide variety of sources, including and local and federal agencies, that conduct groundwater elevation monitoring within the state of California.
DWR continuous groundwater level measurements contains continuous time-series data from automated recorders at sites operated by the Department of Water Resources. Readings are taken at 15-minute to one-hour intervals. Some of the readings are relayed to the California Data Exchange Center. However, most of the monitoring sites are visited once every month or two, when readings are off-loaded from data recorders, then finalized and published. Wells monitored for this dataset are located within Butte, Colusa, Glenn, Mendocino, Modoc, Sacramento, San Joaquin, Shasta, Siskiyou, Solano, Sutter, Tehama, Yolo, and Yuba Counties. Water-level measurements are the principal source of information about changes in groundwater storage and movement in a basin, and how these are affected by various forms of recharge (e.g., precipitation, seepage from streams, irrigation return) and discharge (e.g., seepage to streams, groundwater pumping). Water-level monitoring involves "continuous" or periodic measurements. Continuous monitoring makes use of automatic water-level sensing and recording instruments that are programmed to make scheduled measurements in wells. This provides a high-resolution record of water-level fluctuations. Resulting hydrographs can accurately identify the effects of various stresses on the aquifer system and provide measurements of maximum and minimum water levels in aquifers. Continuous monitoring may be the best technique to use for monitoring fluctuations in groundwater levels during droughts and other critical periods when hydraulic stresses may change at relatively rapid rates, or when real-time data are needed for making water management decisions [see usgs reference](https://ca.water.usgs.gov/sustainable-groundwater-management/groundwater-levels-california.html).

This resource includes a brief fact sheet describing DWR's [Dry Domestic Well Susceptibility Analysis](https://data.cnra.ca.gov/dataset/calgw-live/resource/e0bf3d2b-ceca-41ca-876f-d3e378503583) and [Dry Well Reporting System](https://mydrywell.water.ca.gov). DWR, in coordination with the State Water Resources Control Board, has developed an interactive dashboard, called the Dry Domestic Well Susceptibility within Groundwater Basins Dashboard (Dry Well Susceptibility Dashboard), to identify areas within groundwater basins throughout the State that may be prone to water supply shortages due to domestic drinking water wells going dry. The dashboard identifies the density of "susceptible” domestic wells per square mile based on recent groundwater level measurements and modeled future depth to water. If the modeled future depth to water falls below the dry well depth of a domestic well, the well is labelled susceptible. The Dry Well Susceptibility Dashboard is housed on the California’s Groundwater Live web-based platform which contains the latest information and data on groundwater conditions across the State. The State, local agencies, and well owners can use this dashboard to anticipate where wells may be susceptible to inform drought preparedness decision-making and resource allocation.

This document is Historical, and ends at January 10, 2020. The reason that this document was archived was that the not every record contained a timestamp. For the records that did have a timestamp, the timestamps were placed in the REMARKS field. This issue, along with the document being a PDF file, creates a problem for reading the data into time-series analysis software. For the current Log, see the document, Suisun Marsh Salinity Control Gates Log. The new document is an Excel file that contains the data as a Table. The Table can be sorted or filtered, and can be read by scripting languages such as Python or R. The date and time are stored together in the new, DATETIME field. The GATE 1, GATE 2, and GATE 3 fields have been updated with descriptions that should be easier to understand. A new ACTION field has also been added to concisely and uniformly identify the operational change that occurred. While this archived log contains records going back to November 1, 1998, due to missing data, the new log only contains records going back to May 8, 2018.

__Note__: In these datasets, a person is defined as up to date if they have received at least one dose of an updated COVID-19 vaccine. The Centers for Disease Control and Prevention (CDC) recommends that certain groups, including adults ages 65 years and older, receive additional doses. Starting on July 13, 2022, the denominator for calculating vaccine coverage has been changed from age 5+ to all ages to reflect new vaccine eligibility criteria. Previously the denominator was changed from age 16+ to age 12+ on May 18, 2021, then changed from age 12+ to age 5+ on November 10, 2021, to reflect previous changes in vaccine eligibility criteria. The previous datasets based on age 12+ and age 5+ denominators have been uploaded as archived tables. Starting June 30, 2021, the dataset has been reconfigured so that all updates are appended to one dataset to make it easier for API and other interfaces. In addition, historical data has been extended back to January 5, 2021. This dataset shows full, partial, and at least 1 dose coverage rates by zip code tabulation area (ZCTA) for the state of California. Data sources include the California Immunization Registry and the American Community Survey’s 2015-2019 5-Year data. This is the data table for the [LHJ Vaccine Equity Performance dashboard](https://public.tableau.com/profile/ca.open.data#!/vizhome/LHJVaccineEquityPerformance/MapView?publish=yes). However, this data table also includes ZTCAs that do not have a VEM score. This dataset also includes Vaccine Equity Metric score quartiles (when applicable), which combine the Public Health Alliance of Southern California’s Healthy Places Index (HPI) measure with CDPH-derived scores to estimate factors that impact health, like income, education, and access to health care. ZTCAs range from less healthy community conditions in Quartile 1 to more healthy community conditions in Quartile 4. The Vaccine Equity Metric is for weekly vaccination allocation and reporting purposes only. CDPH-derived quartiles should not be considered as indicative of the HPI score for these zip codes. CDPH-derived quartiles were assigned to zip codes excluded from the HPI score produced by the Public Health Alliance of Southern California due to concerns with statistical reliability and validity in populations smaller than 1,500 or where more than 50% of the population resides in a group setting. These data do not include doses administered by the following federal agencies who received vaccine allocated directly from CDC: Indian Health Service, Veterans Health Administration, Department of Defense, and the Federal Bureau of Prisons. For some ZTCAs, vaccination coverage may exceed 100%. This may be a result of many people from outside the county coming to that ZTCA to get their vaccine and providers reporting the county of administration as the county of residence, and/or the DOF estimates of the population in that ZTCA are too low. Please note that population numbers provided by DOF are projections and so may not be accurate, especially given unprecedented shifts in population as a result of the pandemic.

The data set contains two provisionally assigned values (“DataQuality” and “DataQualityIndicator”) to help users interpret the data quality metadata provided with the associated result. Due to file size limitations, the data has been split into individual resources by year. The entire dataset can also be downloaded in bulk using the zip files on this page (in csv format or parquet format), and developers can also use the API associated with each year's dataset to access the data. Users who want to manually download more specific subsets of the data can also use the **[CEDEN Query Tool](https://ceden.org/find_data_page.shtml)**, which provides access to the same data presented here, but allows for interactive data filtering. **NOTE:** Some of the field and lab chemistry data that has been submitted to CEDEN since 2020 has not been loaded into the CEDEN database. That data is not included in this data set (and is also not available via the CEDEN query tool described above), but is available as a supplemental data set available here: **[Surface Water - Chemistry Results - CEDEN Augmentation](https://data.ca.gov/dataset/surface-water-chemistry-results-ceden-augmentation)**. For consistency, many of the conditions applied to the data in this dataset and in the CEDEN query tool are also applied to that supplemental dataset (e.g., no rejected data or replicates are included), but that supplemental data is provisional and may not reflect all of the QA/QC controls applied to the regular CEDEN data available here.

This resource contains a zipped set of files in the Apache Parquet file format (see: **https://parquet.apache.org/**), which include all of the eSMR analytical data from 2006 through present, partitioned by region (the [California Water Board Region](https://www.waterboards.ca.gov/waterboards_map.html) where the sampling site is located) and year (the calendar year in which the sample was taken). Parquet is a free and open source data storage format that allows for fast and efficient processing of large datasets. It is compatible with a variety of data analysis platforms, including the R and Python programming languages, through the Apache Arrow platform (see: **https://arrow.apache.org/**). See **[here](https://gist.github.com/daltare/d76d63360050810f99ae8d7a6b4d1443)** for an example showing how to use this dataset with the R programming language. The data in this dataset is essentially identical to that contained in the csv files for the individual years (with the exception that missing values in numeric and date fields are encoded as "NA" rather than "NaN" or empty text strings), and is included here as an alternative option for for users who want a bulk download of all of the eSMR data made available on the open data portal.

Seasonal ETo, Peff, and ETF data are provided for calculating agricultural variances for suppliers that have qualifying urban agriculture acreage in their service area. Seasonal values are weighted average values that are calculated based on crop acreages within the service area boundaries. Crop acreages are derived from DWR’s land use data layer ([CADWR Land Use Viewer](https://gis.water.ca.gov/app/CADWRLandUseViewer/?page=home)). The evapotranspiration fraction (ETF) was calculated from weighted average values of crop coefficient (Kc) and irrigation efficiency (IE), which are also provided in this file. The tables from which this dataset have been compiled are released by the Department of Water Resources per fiscal year at [this page](https://data.cnra.ca.gov/dataset/dwr-urban-water-use-objective-data).

This table contains fields from potable and non-potable water demand data reported by public water systems owned and operated by urban retail water suppliers. The list of public water systems in this resource is based on the PWSID-DWRID crosswalk resource that is also a part of the Urban Water Use Objectives dataset. Consistent with Health and Safety Code section 116530, public water systems submit a technical report to the Board in a form and format and at intervals specified by the state; these data are submitted through the [SAFER Clearinghouse](https://www.waterboards.ca.gov/drinking_water/certlic/drinkingwater/clearinghouse_drought_conservation_reporting.html). For each system, the table includes potable and non-potable water use data, if provided by the supplier. All values have been converted to gallons by State Water Board staff. If the values identified in this dataset need to be revised, a supplier may reopen an already submitted report in the SAFER Clearinghouse to revise and re-submit. For more instructions on how to revise a report, consult the Clearinghouse Reporting User Guide [found here](https://www.waterboards.ca.gov/drought/resources-for-drinking-water-systems/docs/clearinghouse-reporting-user-guide.pdf).
Potable and Non-Potable Water Deliveries for URWS
This dataset contains fecal indicator bacteria (FIB) monitoring results collected from surface waters across California. It includes results for _Escherichia coli_ (E. coli), enterococci, fecal coliforms, and total coliforms - key indicators used to assess microbial water quality and potential health risks associated with recreational water use. The data has been cleaned and standardized to ensure consistency and usability. For each valid data point, the dataset also includes calculated 6-week and 30-day geometric means, which are commonly used to evaluate long-term water quality trends and compliance with bacteria water quality objectives. Some records are excluded from the final dataset during processing. These typically include duplicate or replicate results, records with missing or invalid result values, or any data that cannot be used to calculate a geometric mean. These records are saved to the "Excluded Records" data resource. This dataset serves as the primary data source for the Water Boards My Water Quality Portal [Safe to Swim Map](https://mywaterquality.ca.gov/safe-to-swim/content/interactive_map/index.html), which provides the public with timely information about potential health risks associated with water contact recreation at monitored sites. Data is sourced from the [California Environmental Data Exchange Network](https://ceden.org/) (CEDEN) database, BeachWatch database, and the Central Valley Water Board [Lower American River Recreational Water Quality Map](https://experience.arcgis.com/experience/47e27f245e044ac2a8e15083307e75f6/?draft=true&org=waterboards). There is some overlap with the [CEDEN Water Chemistry dataset](https://data.ca.gov/dataset/surface-water-chemistry-results). Both portal datasets draw from the same source, but the resources here are updated more frequently to support the Safe to Swim map.

Borehole extensometers are a more site specific method of measuring land subsidence. These instruments consist of a pipe or cable anchored at the bottom of a well casing. Pipe or cable extend from the bottom of the well, through geologic layers susceptible to compaction, to the ground surface. The pipe or cable is connected to a recorder that measures the relative distance between the bottom of the bore hole to the ground surface. These instruments are capable of detecting changes in land surface elevation to 1/100th of a foot. When land subsidence and water depth monitoring activities are paired together, hydraulic and mechanical properties of the aquifer system can be determined. DWR monitors 11 extensometers in the Sacramento Valley. For more information regarding land subsidence monitoring vist: http://www.water.ca.gov/groundwater/landsubsidence/LSmonitoring.cfm

2007 Ambulatory Surgery - External Cause of Injury/Morbidity Code Frequency
This data table reports the annual number of deaths that occurred in each California county regardless of the place of residence (by occurrence) and deaths to residents of each California county (by residence). The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed will affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not take into account contributing causes of death.

This data table reports the provisional monthly number of deaths that occurred in each California county regardless of the place of residence (by occurrence). __Provisional counts are based on the records available when the data was retrieved, given by Data\_Extract\_Date, and may not represent all deaths that occurred during the time period.__ Deaths involving injuries from external or environmental forces, such as accidents, homicide and suicide, often require additional investigation that tends to delay certification of the cause and manner of death. This can result in significant under-reporting of these deaths in provisional data. The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed can affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not always take into account all conditions contributing to the death. Cause of death categories for years 1999 and later are based on tenth revision of International Classification of Diseases (ICD-10) codes. Comparable categories are provided for years 1979 through 1998 based on ninth revision (ICD-9) codes. For more information on the comparability of cause of death classification between ICD revisions see [Comparability of Cause-of-death Between ICD Revisions](https://www.cdc.gov/nchs/nvss/mortality/comparability_icd.htm).

Interactive pop-ups display zone-specific cone bushel need and surplus and natural disturbance data to non-federal conifer forests. Disturbance data includes total and high-severity acreage burned by large wildfires, acreage affected by insects and disease, and tree mortality due to such diseases. Supplementary layers include CAL FIRE timber harvesting data, demonstration state forests, and administrative boundaries, such as parcel information and land ownership.
California Seed Bank Assessment of Need App
CAL FIRE's Fire and Resource Assessment Program (FRAP) annually maintains and distributes an historical fire perimeter dataset from across public and private lands in California. The GIS data is developed with the cooperation of the United States Forest Service Region 5, the Bureau of Land Management, the National Park Service and the United States Fish and Wildlife Service and is released in the spring with added data from the previous calendar year. Although the dataset represents the most complete digital record of fire perimeters in California, it is still incomplete, and users should be cautious when drawing conclusions based on the data. This app contains three pages of maps and documentation of the historical fire perimeter metadata: Historical Fire Perimeters: The landing page highlights the recent large fires (≥5,000 acres) on a backdrop of all of the dataset's documented fire perimeters dating back to 1878. This map includes perimeters symbolized by decade, county boundaries, California Vegetation, and NAIP imagery back to 2005. This page provides users the ability to add their own data or filter the fire perimeter data. It cleanly lists fire perimeters shown on the map with their name, year, and GIS calculated acreage.

DWR has a long history of studying and characterizing California’s groundwater aquifers as a part of [California’s Groundwater (Bulletin 118)](https://water.ca.gov/Programs/Groundwater-Management/Bulletin-118 "California’s Groundwater (Bulletin 118)"). [California's Groundwater Basin Characterization Program](https://water.ca.gov/Programs/Groundwater-Management/Bulletin-118/Basin-Characterization "California's Groundwater Basin Characterization Program") provides the latest data and information about California’s groundwater basins to help local communities better understand their aquifer systems and support local and statewide groundwater management. Under the Basin Characterization Program, new and existing data (AEM, lithology logs, geophysical logs, etc.) are integrated to create continuous maps and three-dimensional models. To support this effort, new data analysis tools have been developed to create texture models, hydrostratigraphic models, and aquifer flow parameters. Data collection efforts have been expanded to include advanced geologic, hydrogeologic, and geophysical data collection and data digitization and quality control efforts will continue. To continue to support data access and data equity, the Basin Characterization Program has developed new online, GIS-based, visualization tools to serve as a central hub for accessing and exploring groundwater related data in California. Additional information can be found on the [Basin Characterization Program webpage](https://water.ca.gov/Programs/Groundwater-Management/Bulletin-118/Basin-Characterization "Basin Characterization Program webpage"). #Local, Regional, and Statewide Groundwater Investigations DWR is undertaking local, regional, and statewide investigations to evaluate California's groundwater resources and develop state-stewarded maps and models. The following section describes the work being conducted in each area and links to view available datasets. ##Local Investigations + [Madera & North Kings](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/8400c923-e18d-4ac5-958b-82f88e5af4f8 "Madera & North Kings"): AEM data collection, lithology log digitization, texture model development, aquifer recharge potential mapping analysis. + [Pajaro](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/043aaa87-5c5d-433e-9afe-80f6966ca3ad "Pajaro"): AEM and tTEM data collection + [Western San Joaquin Valley](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/c2633b9c-cd34-445b-ac2d-4a5b49eb881d "Western San Joaquin Valley"): AEM data collection, lithology and geophysical log data digitization, texture model development. + [Prospect Island](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/b96e8832-d8af-416e-abcd-9240f7fb33d4 "Prospect Island"): AEM data collection, FloaTEM data collection test. ##Regional Investigations + [Sacramento Valley](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/fed9f9dd-fd0d-4ef6-a21b-a8835404b3c6 "Sacramento Valley"): AEM data collection, texture model development, aquifer recharge potential mapping analysis. + [Four County Area of San Joaquin Valley (Madera, Fresno, Kings, and Tulare counties) ](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/a19efaf7-c0c0-4816-bcdc-1c1010a38ab3 "Four County Area of San Joaquin Valley (Madera, Fresno, Kings, and Tulare counties) "): AEM data collection, data digitization, texture model development, hydrogeologic conceptual model development, clay delineation, subsidence potential and mitigation, and aquifer recharge potential mapping analysis. + [San Joaquin Valley](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/19ea1234-6545-41c9-aeb2-f655d6599286 "San Joaquin Valley"): AEM data collection, data digitization, texture model development, hydrogeologic conceptual model development, clay delineation, subsidence potential and mitigation, and aquifer recharge potential mapping analysis. ##Statewide Investigations + [Statewide AEM Surveys](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/c9297796-80fb-4a0c-9464-5ec7a12c24bf "Statewide AEM Surveys"): AEM data collection, geophysical and lithology log data digitization. # [Maps and Models](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/6b4823ed-e1e6-4a91-b1c6-f88423962f90 "Maps and Models") New and existing data have been combined and integrated using the analysis tools described below to develop maps and models that describe grain size, the hydrostratigraphic properties, and hydrogeologic conceptual properties of California’s aquifers. These maps and models help groundwater managers understand how groundwater is stored and moves within the aquifer. The models will be state-stewarded, meaning that they will be regularly updated, as new data becomes available, to ensure that up-to-date information is used for groundwater management activities. The first iterations of the following maps and models will be published as they are developed: + Texture Models + Hydrostratigraphic Models + Aquifer Recharge Potential Maps + Extent of Corcoran Clay + Base of Freshwater # Data Collection & Digitization ## [Collected Geophysical Data](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/32347fa2-cadb-4994-88aa-6e9a87914c4e "Collected Geophysical Data") As a part of the Basin Characterization Program, advanced geologic, hydrogeologic, and geophysical data will be collected to improve our understanding of groundwater basins. Data collected under Basin Characterization are collected at a local, regional, or statewide scale depending on the scope of the study. Geophysical data collection methods include: + Airborne electromagnetics (AEM) + All-terrain vehicle towed electromagnetics (tTEM) + Floating towed electromagnetics (FloaTEM) + Geophysical borehole logging ## [Digitized Lithology and Geophysical Logs](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/942aa75e-8727-4e12-84a6-280b5896f3b0 "Digitized Lithology and Geophysical Logs") Lithology and geophysical logging data have been digitized to support the Statewide AEM Survey Project and will continue to be digitized to support Basin Characterization efforts. All digitized lithology logs with Well Completion Report IDs will be imported back into the OSWCR database. Digitized lithology and geophysical logging can be found under the following resource: #[Analysis Tools and Process Documents](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/ffcfe414-9221-4ddd-970c-40e83c65909b "Analysis Tools and Process Documents") To develop the state-stewarded maps and models outlined above, new tools and process documents have been created to integrate and analyze a wide range of data, including geologic, geophysical, and hydrogeologic information. By combining and assessing various datasets, these tools help create a more complete picture of California's groundwater basins. All tools, along with guidance documents, are made publicly available for local groundwater managers to use to support development of maps and models at a local scale. All tools and guidance will be updated as revisions to tools and process documents are made. ##Data Analysis Tools + [Data2Texture](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/91b11192-9867-4020-82f0-df795d6eb7b4 "Data2Texture"): Data2Texture is an advanced spatial data interpolation tool for estimating the distribution of sediment textures from airborne electromagnetic data and lithology logs to create a 3D texture model + [Data2HSM - Smart Interpretation](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/a00585a3-d330-41b1-aeba-f450526596b9 "Data2HSM - Smart Interpretation"): Data2HSM via Smart Interpretation (SI) is a semi-automatic Python tool for delineating continuous hydrogeologic surfaces from airborne electromagnetic data products. + [Data2HSM - Gaussian Mixture Model](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/14a82d4c-c6f7-4d13-8189-91cada79f867 "Data2HSM - Gaussian Mixture Model"): The Data2HSM via Gaussian Mixture Model tool ingests the AEM data and groups the data into a user-specified number of clusters that are interpreted as stratigraphic units in the hydrostratigraphic model (HSM) + [Data2HSM - Geological Pseudolabel Deep Neural Network](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/ab9d4d5b-0c7a-4374-a3bc-1ad6f1c25621 "Data2HSM - Geological Pseudolabel Deep Neural Network"): The GeoPDNN (Geological Pseudolabel Deep Neural Network) is a semi-supervised machine learning tool that integrates lithologic well logs and AEM data into plausible stratigraphic surfaces. + [Texture2Par V2](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/ef60d3ee-91d3-40cc-9455-5b9775993ee5 "Texture2Par V2"): Texture2Par V2 is a groundwater model pre-processor and parameterization utility developed to work with the IWFM and MODFLOW families of hydrologic simulation code. ##Process Documents + [Aquifer Recharge Potential Mapping](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/7d33d618-38bc-4511-834c-6e791695f8e2 "Aquifer Recharge Potential Mapping"): The Aquifer Recharge Potential (ARP) Mapping Process Document provides a framework for identifying locations that have relatively higher potential for managed aquifer recharge. #Data Visualization Data access equity is a priority for the Basin Characterization Program.

This dataset represents the list of CA WIC authorized food items identified by food category and subcategory. Each item is uniquely identified by a Universal Product Code (UPC) or Price Look-Up code (PLU) for WIC electronic benefit transfer (EBT). The WIC Authorized vendors use the CA Authorized Product List (APL) to transact WIC food items at cash registers. The APL plays a crucial role in supporting WIC EBT purchases. WIC EBT requires vendor systems to maintain the APL to match the scanned food items' UPCs to ensure they are on the APL. The food items identified by UPC and PLU can be found in the data files below. When you download the files, Excel may prompt you to automatically format the data. If prompted, you may want to hit ‘Don’t Convert’ so that Excel leaves the data as is without any formatting or data conversions. The Women, Infants and Children (WIC) Program is a federally-funded health and nutrition program that provides assistance to pregnant women, new mothers, infants, and children under age five. WIC helps California families by providing food benefits to individual participants based on their nutritional need and risk assessment. The food benefits can be used to purchase healthy supplemental foods from approximately 3,800 WIC authorized vendor stores throughout the State. WIC also provides nutritional education, breastfeeding support, healthcare referrals, and other community services. Participants must meet income guidelines and other criteria. Currently, 84 WIC agencies provide services monthly to approximately one million participants at several hundred sites in local communities throughout the State.

The Making Conservation a California Way of Life regulation requires urban retail water suppliers (URWS) to annually calculate their Urban Water Use Objective (UWUO), which is the sum of efficiency budgets for a subset of urban water uses: residential indoor water use, residential outdoor water use, real water loss and commercial, industrial and institutional landscapes with dedicated irrigation meters. Each efficiency budget will be calculated using a statewide efficiency standard and local service area characteristics such as population, climate, and landscape area. Where relevant, suppliers may also include in their objective “variances” for unique uses, or a bonus incentive for potable recycled water use. This dataset contains information gathered from reports submitted to the State Water Board, the Department of Water Resources, and other relevant information sources. It also contains information derived by the Board and the Department for the purpose of the regulation. The values in these tables are used to pre-fill a number of fields within the UWUO reporting form that URWS are required to submit by January 1 of each year, starting in 2025. To view the submitted values, please visit [this page](https://data.ca.gov/dataset/urban-water-use-objectives-compiled-report-data).

Habitat data for year 2024 from the California Environmental Data Exchange Network (CEDEN).
This data table reports the provisional monthly number of deaths that occurred in California regardless of the place of residence (by occurrence). __Provisional counts are based on the records available when the data was retrieved, given by Data\_Extract\_Date, and may not represent all deaths that occurred during the time period.__ Deaths involving injuries from external or environmental forces, such as accidents, homicide and suicide, often require additional investigation that tends to delay certification of the cause and manner of death. This can result in significant under-reporting of these deaths in provisional data. The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed can affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not always take into account all conditions contributing to the death. Cause of death categories for years 1999 and later are based on tenth revision of International Classification of Diseases (ICD-10) codes. Comparable categories are provided for years 1979 through 1998 based on ninth revision (ICD-9) codes. For more information on the comparability of cause of death classification between ICD revisions see [Comparability of Cause-of-death Between ICD Revisions](https://www.cdc.gov/nchs/nvss/mortality/comparability_icd.htm).

Hazardous waste identification (ID) numbers are issued by the U.S. Environmental Protection Agency (Federal EPA ID number) or by the Department of Toxic Substances Control (California State ID number). The ID number identifies each handler of hazardous waste on hazardous waste manifests and other paperwork. The ID number enables regulators to track the waste from its origin to final disposal, a process also referred to as “cradle to grave.” With a few exceptions, most hazardous waste generators must have an ID number before a registered hazardous waste transporter will accept their waste for shipment. All hazardous waste transporters and permitted treatment, storage, and disposal facilities (TSDFs) must have a hazardous waste ID number.

This dataset supports the [SWAMP Data Dashboard](https://gispublic.waterboards.ca.gov/swamp-data/), a public-facing tool developed by the [Surface Water Ambient Monitoring Program](https://www.waterboards.ca.gov/water_issues/programs/swamp/) (SWAMP) to provide accessible, user-friendly access to water quality monitoring data across California. The dashboard and its associated datasets are designed to help the public, researchers, and decision-makers explore and download monitoring data collected from California’s surface waters. This dataset includes five distinct resources: * __SWAMP Stations__ – Geospatial and descriptive information about SWAMP monitoring sites. * __Water Quality Results__ – Field and lab analysis results for chemical and physical parameters measured in water samples. * __Toxicity Summary Results__ – Summarized results from aquatic toxicity tests. Summary records are entries in the database that summarize the results from multiple replicate toxicity tests of the same sample water. * __Habitat Results__ – Data on physical habitat conditions typically collected alongside biological monitoring to provide context for interpreting water quality conditions. Includes scores for the California Stream Condition Index (CSCI) and Algal Stream Condition Index (ASCI). * __Tissue Summary Results__ – Annual summary statistics of contaminant concentrations in aquatic organism tissue samples. The data are derived from raw individual and composite tissue sample results. These data are collected by SWAMP and its partners to support water quality assessments, identify trends, and inform water resource management. The SWAMP Data Dashboard provides interactive visualizations and filtering tools to explore this data by region, parameter, and more. The SWAMP dataset is sourced from the [California Environmental Data Exchange Network](https://ceden.org/) (CEDEN), which serves as the central repository for water quality data collected by various monitoring programs throughout the state. As such, there is some overlap between this dataset and the broader CEDEN datasets also published on the California Open Data Portal (see Related Resources). This SWAMP dataset represents a curated subset of CEDEN data, specifically tailored for use in the SWAMP Data Dashboard. Access the SWAMP Data Dashboard: https://gispublic.waterboards.ca.gov/swamp-data/ _*This dataset is provisional and subject to revision. It should not be used for regulatory purposes._

This reference table, maintained by DHCS, displays aid code categories by aid code. Aid codes identify the criteria by which each person qualifies for Medi-Cal and the types of services he or she receives, and make clear whether the services are funded by the State or Federal government or both. An aid code is a combination of two numbers or a letter and a number and is attached to a Medi-Cal beneficiary’s identification numbers. Aid code category refers to a unique grouping of distinct aid codes into broad categories such as CHIP, Seniors and Persons with Disabilities, and Long-Term Care. For a description of each aid code, see the [Medi-Cal Aid Code Master Chart](https://files.medi-cal.ca.gov/pubsdoco/publications/masters-mtp/part1/aidcodes.pdf "Medi-Cal Aid Code Master Chart").

Groundwater levels at selected wells were analyzed using the Mann-Kendall non-parametric test to determine whether a statistically significant trend (declining trend, no trend, or increasing trends in groundwater levels) was present during the specified time period. To ensure sufficient data quality and temporal coverage, each well included in the analysis must meet minimum data requirements: at least 10 unique years of spring measurements, and those spring measurements must span at least 15 years within the 20-year period. When more than one spring measurement was available for a year, the highest (shallowest) water level was selected to represent that year. If a statistically significant trend was observed, the Theil-Sen method was used to calculate the estimated slope of the trend line to quantify the decline or increase. These trends are derived from the DWR Periodic Groundwater Levels dataset that contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Most measurements are taken manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements This service is under development as part of ongoing enhancements to CalGW Live. DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data.

Water Shortage Vulnerability Technical Documents
The Water Conservation Act of 2009 (Senate Bill X7-7) was enacted in November 2009 and required that all water suppliers increase their water use efficiency. Water Code section 10608.20 directed urban retail water suppliers (suppliers) to develop 2020 urban water use targets. This table contains the suppliers’ individual SB X7-7 targets. Because some suppliers deducted discrete demands from gross water use when calculating their 2020 urban water use targets, the table also contains the volume of those deducted demands, specifically for indirect recycled water and process water. Water Code section 10608.20(a)(1) and 10608.28 provided that suppliers may plan, comply, and report on a regional basis, individual basis, or both. Each group of water suppliers agreeing among themselves to plan, comply, and report as a region is referred to as a “regional alliance.” For those suppliers that took part in a regional alliance, this table also lists the regional alliance name and indicates whether the regional alliance has met its target. All data within this table were derived from the [2020 Urban Water Management Plans Open Data](https://data.ca.gov/dataset/2020-uwmp-data-export-tables), which were created using data submitted by suppliers to Department. Specifically, this table was created using the following fields: * Individual SB X7-7 target from Tab SB_X7-7_CF_Table_9, column K * Indirect recycled water volume from Tab SB_X7-7_CF_Table_4, column J * Process water volume from Tab SB_X7-7_CF_Table_4, column L * Recycled and process water units from Tab SB_X7-7_VF_Table_0, column F * Regional alliance name from Tab SB_X7-7_CF_Table_9 * Whether the regional alliance met its target Tab Regional_Alliance_Summary, column F As described in the [2020 Urban Water Management Guidebook](https://water.ca.gov/-/media/DWR-Website/Web-Pages/Programs/Water-Use-And-Efficiency/Urban-Water-Use-Efficiency/Urban-Water-Management-Plans/Final-2020-UWMP-Guidebook/UWMP-Guidebook-2020---Final-032921.pdf)[(Appendix P.3.2)](https://water.ca.gov/-/media/DWR-Website/Web-Pages/Programs/Water-Use-And-Efficiency/Urban-Water-Use-Efficiency/Urban-Water-Management-Plans/Final-2020-UWMP-Guidebook/Appendix-P---UWMP-2020.pdf), a supplier’s target may be updated if its service area has changed because of a consolidation, merger, annexation, expansion, or contraction.

The California Department of Public Health (CDPH) is coordinating with wastewater utilities, local health departments, academic researchers, and laboratories in California on wastewater surveillance for infectious disease pathogens of interest to public health (such as SARS-CoV-2, the virus causing COVID-19, influenza, respiratory syncytial virus (RSV), mpox, and norovirus). Data collected from this network of participants, called the California Surveillance of Wastewaters (Cal-SuWers) Network, are submitted to the U.S. Centers for Disease Control and Prevention (CDC) National Wastewater Surveillance System (NWSS). Collecting and analyzing wastewater samples for the presence of, and amount of (concentration), a specified pathogen target can help inform public health about circulation of that infectious disease within a community. Data from wastewater testing do not replace existing public health surveillance systems but complement them. While wastewater surveillance cannot determine the exact number of infected persons in the area being monitored, it can provide overall trends of pathogen concentration within that community. Please note that data included in the Cal-SuWers Network and available here originate from multiple programs and laboratories. Methodologies for producing wastewater data are not currently standardized, and analyses, comparisons, and aggregations should be done with caution. Wastewater is a complex environmental sample and inherent variability in measured concentrations is expected due to environmental variability, day-to-day differences in sewershed and population dynamics, differences in the amount of shedding between people and pathogens, and laboratory and sampling variability. Please see the CDPH Cal-SuWers, CDC NWSS, and CDC Public Health interpretation and Use of Wastewater Surveillance data webpages for more information. Historical wastewater data can be found [here](https://data.ca.gov/dataset/covid-19-wastewater-surveillance-data-california).
