The following datasets are used for the Water Rights Demand Analysis project and are formatted to be used in the calculations. The State Water Resources Control Board Division of Water Rights (Division) has developed a methodology to standardize and improve the accuracy of water diversion and use data that is used to determine water availability and inform water management and regulatory decisions. The Water Rights Demand Data Analysis Methodology (Methodology https://www.waterboards.ca.gov/drought/drought_tools_methods/demandanalysis.html ) is a series of data pre-processing steps, R Scripts, and data processing modules that identify and help address data quality issues related to both the self-reported water diversion and use data from water right holders or their agents and the Division of Water Rights electronic water rights data.

This list includes detail information about the measurement devices and measurement methods associated with the diversion and storage of water as reported annually for water rights as stored in the State Water Resources Control Board's "Electronic Water Rights Information Management System" (EWRIMS) database. All water right holders are required to submit an annual report including information related to the measurement devices and measurement methods associated with the diversion or storage of water. Each row correspond with a unique annual report-water right id-and measurement device ID combination and its associated data. This file is in flat file format and may not include all information associated to a water right such all uses and seasons or the amounts reported used for every month. Other information may be available in the associated flat files for each category. Examples of annual reports templates are provided as supporting information.

This list includes detail information for WATER USE as reported annually under each water right as stored in the State Water Resources Control Board's "Electronic Water Rights Information Management System" (EWRIMS) database. All water right holders are required to submit an online report of water diversion and use detailing their monthly water diversion, storage and use (even if no water was diverted or used during the period). The information is required pursuant to Title 23, Sections 847 and 925, of the California Code of Regulations. The annual report contains information about the water diversion and use. Each row correspond with a unique annual report-water right id, month and diversion type combination and its associated data. The list include basic summary information about the Water Right record, such as the type and status, the location of the Points of Diversion, the amount of water allowed (Face Value), and summary data associated with the electronic Water Right record. This file is in flat file LONG format and may not include all information associated to a water right such all uses and seasons. The information associated with crop irrigation is not included in this list but is included on a separate file. Other information may be available in the associated flat files for each category. Examples of annual reports templates are provided as supporting information. The dataset is also available in "Wide Format" by reporting year using the eWRIMS public report system here https://ciwqs.waterboards.ca.gov//ciwqs/ewrims/reportingDiversionDownloadPublicSetup.do

This file is in flat file format and may not include all information associated to a water right such all Points of Diversion, all uses and seasons or the amounts reported used for every month. That information may be available in the associated flat files for each category.

This list includes detail information as reported annually under each water right as stored in the State Water Resources Control Board's "Electronic Water Rights Information Management System" (EWRIMS) database. All water right holders are required to submit an online report of water diversion and use detailing their annual water use (even if no water was diverted or used during the period). The report is the record of actual water diversion and use made under the water right permit. The information is required pursuant to Title 23, Sections 847 and 925, of the California Code of Regulations. Information provided in the report may be used by the State Water Board to evaluate compliance with permit terms and conditions. The annual report contains information about the water diversion and use, measuring devices, water storage, statement of compliance, project status (for permits), special uses, rates of diversion, water supply contracts, water conservation, water transfers, conjunctive use, etc. Each row correspond with a unique annual report-water right id combination and its associated data. The list include basic summary information about the Water Right record, such as the type and status, the location of the Points of Diversion, the amount of water allowed (Face Value), and summary data associated with the electronic Water Right record. This file is in flat file format and may not include all information associated to a water right such all uses and seasons or the amounts reported used for every month. The information associated with crop irrigation is not included in this list but is included on a separate file. Other information may be available in the associated flat files for each category.

This list includes detail information for each enforcement action record as stored in the State Water Resources Control Board's "Electronic Water Rights Information Management System" (EWRIMS) database. Each row is represent the unique enforcement action record and the associated investigation, number of violations, complaints, the "Points of Investigation" (POI) and the associated water rights Application ID (unique identifier for a water right). Not all enforcement actions are associated to a water right so there may not be any water right associated to the enforcement action and one enforcement action may be associated with multiple water right IDs. This file is in flat file LONG format and does not include all the information associated to a water right such all uses and seasons. Other information may be available in the associated flat files for each category. https://ciwqs.waterboards.ca.gov//ciwqs/ewrims/EWMenuPublic.jsp https://www.waterboards.ca.gov/waterrights/water_issues/programs/enforcement/

This list includes detail information about every Point of Investigation (POI) water rights record in the State Water Resources Control Board's "Electronic Water Rights Information Management System" (EWRIMS) database. A Point of Investigation is the geographic area associated to a water right investigation. POI is a location of interest during an investigation and there may be several POIs in an investigation. Generally, POIs can be permit/license/statement PODs, places of use, point of alleged unauthorized diversion, place of alleged unauthorized use. Each row in the dataset corresponds with a unique Point of Investigation ID and its associated data. The list include basic summary information about the Water Right Investigation record, such as the type and status, the location of the Point of Investigation, the inspections and summary data associated with the electronic Water Right record. This file is in flat file format and may not include all information associated to a water right such all uses and seasons or the amounts reported used for every month. That information may be available in the associated flat files for each category.
