Demand Analysis Water Use
THIS LIST IS NOT AUTHORITATIVE. IT WAS DERIVED AND FORMATTED SPECIFICALLY FOR USE IN THE DEMAND ANALYSIS PROJECT. For the Authoritative Version please navigate to: https://data.ca.gov/dataset/california-water-rights-water-use-reported. 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.
