Butte Subbasin Groundwater Sustainability Plan

The Butte Subbasin is identified by California Department of Water Resources (DWR) as a medium priority basin. Therefore, the Butte Subbasin GSAs must develop, adopt, and submit a GSP (or GSPs) to DWR for the entire Butte Subbasin by January 31, 2022. The Butte Subbasin is managed by eleven GSAs, which are working together under a Subbasin Cooperation Agreement1 to develop one GSP for the entire Subbasin. This Butte Subbasin GSP satisfies the requirements established by SGMA and DWR, and outlines the strategy by which the Butte Subbasin GSAs will maintain sustainable groundwater management through the implementation period until 2042.
