Water Reporting Requirements for Operators

The Division of Oil, Gas, and Geothermal Resources (DOGGR) collects detailed water-use information in accordance with Oil and Gas Production: Water Use: Reporting, Senate Bill 1281 (2014) amendments to Public Resources Code (PRC) Section 3227. The submitted information is known as the quarterly water report.

Oil and gas well operators have one month after the end of the quarter to file the quarterly water report. 

Operators can submit the required report in WellSTAR, the Well Statewide Tracking and Reporting online database system. Those who do not use WellSTAR must file their report at their local DOGGR district office. On the day of their appointment, they can use DOGGR's public-use computer to access, complete, and file their report.
