California Water Rights Annual Reports (Detail Summary List)

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. Examples of annual reports templates are provided as supporting information.
