Urban Retail Water Supplier - Water Conservation, Supply, and Demand (June 2014 onwards)
Monthly reports of water use and conservation activities by urban retail water suppliers, which are generally defined as agencies serving over 3,000 service connections or deliveries 3,000 acre-feet of water annually for municipal purposes. The most recent reporting period generally lags by about 2 months, due to the reporting deadline and the necessary subsequent dataset preparation. The full dataset that spans June 2014 to the most recent reporting period is the Per-Supplier Water Supply and Demand resource, which is an updated version of the dataset previously released on the Water Board's [Water Conservation Portal](https://www.waterboards.ca.gov/water_issues/programs/conservation_portal/conservation_reporting.html). Other datasets include the per-water-system supply and demand, representing a subset of the SAFER Clearinghouse dataset, and the conservation actions datasets. See the documentation PDF for data dictionaries and an explanation of the data flag methodology.
