Frequently Asked Questions

Any person that extracts groundwater from an unmanaged area or a probationary basin must file a groundwater extraction report with the State Water Board. The State Intervention Page provides details on unmanaged areas and probationary basins.

A well owner who extracts two acre‐feet or less per year from a parcel for domestic purposes is a de minimis user. Domestic purposes do not include commercial activities. A well owner who extracts more than two acre-feet per year from a parcel is not a de minimis user. De minimis users in unmanaged areas are exempt from reporting. However, the State Water Board can require reporting by de minimis users in probationary basins if necessary to manage the basin. The Domestic Well Brochure (pdf) provides details on de minimis extractors. The State Water Board may also choose to exclude a class or category of extractions from reporting pursuant to Water Code section 10735.2(c).

You are automatically required to file a groundwater extraction report to the State Water Board if you extract groundwater in an unmanaged area and do not meet one of the exceptions described above. The State Water Board plans to notify groundwater extractors of their reporting requirement in August of each year. If you are extracting groundwater from an unmanaged area and do not receive a notification letter from the State Water Board you are still required to file a groundwater extraction report.
