California Water Rights Petitions LIST
This list includes detail information about every Petition associated to a water rights record and stored in the State Water Resources Control Board's "Electronic Water Rights Information Management System" (EWRIMS) database. The State Water Board's Division of Water Rights administers California's water rights system. Parties can petition to modify their existing post-1914 water right permits or licenses as their projects change, or if they wish to transfer water to another party. These approvals can be temporary or can be permanent. Parties with permits may also request additional time to develop their project. There are also types of petitions that can be used by other types of water right holders. For example, parties holding pre-1914 or riparian claims can submit instream flow dedications to allow some of their water to remain instream and benefit instream uses. The Division of Water Rights also processes petitions submitted by wastewater treatment plant operators who wish to decrease their discharges to a stream. Each row correspond with a unique Petition ID and its associated data. The list include basic summary information about the Water Right record, such as the type and status, the location associated to the Petition, 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.

More details
"Additional Information: The unique identifier for the dataset is ""Petition ID"". The dataset provides one record per petition id and all the existing associated data to that record. In most cases one to many relationships are resolved by providing an aggregate of the values, the most relevant or recent value, or a reduced number of the most relevant values in the dataset. For example, if a Petition has more than one water right associated, the dataset includes details of the water right with the most recent updated date. It also provides the number of water rights to the Petition. Limitations: “Use of this data is subject to the CA.gov Conditions of Use and any copyright and proprietary notices incorporated in or accompanying the individual files.” Data Methodology: The data is maintained in the eWRIMS database by authorized staff in the Division of Water Rights and is an electronic representation of the actual legal water right documents. Some of the data records may not be complete or up to date. Some of the data is directly reported by the Water Right holders and may have not been reviewed or verified for accuracy and completeness (QAQC)."
