CalWATRS Water Rights Geospatial Data
This dataset links California water rights, applications, and claims to the mapped features that define them: points of diversion, rediversion, and storage, places of use and storage, facilities, and lines of conveyance.
Each link is single-use: it describes the relationship between one water right or claim (or change petition) and one feature at a point in time. A right with several points of diversion appears on several rows, and a point shared by several rights appears once for each right.
Each link has a status of Active or Inactive. Many links were migrated from the Electronic Water Rights Information Management System (eWRIMS) and have no start or end date. Links created in CalWATRS get a start date, and a link whose status changes in CalWATRS gets an end date.
Point features include latitude and longitude (WGS 84) and northing and easting (California Albers, EPSG:3310). County, watershed (Hydrologic Unit Code, HUC), and Public Land Survey System location are calculated by CalWATRS. Places of use and storage, facilities, and lines of conveyance are listed without their shapes.
**Update Frequency:** Weekly
