Sustainable Groundwater Management Act

Sustainable Groundwater Management Act

On September 16, 2014, Governor Brown signed into law a package of bills (SB1168, AB1739 and SB1319) collectively called the Sustainable Groundwater Management Act. The Tehama County Flood Control and Water Conservation District was recognized by DWR as the Exclusive Groundwater Sustainability Agency on February 11, 2016, for the 11 groundwater subbasins or the portions of those subbasins located within Tehama County. The District also submitted a Basin Boundary Adjustment in March 2016 to incorporate the small portion of the Colusa Subbasin located within Tehama County into the Corning Subbasin. The District formed the Groundwater Commission in November 2016 and is starting the process of developing a Groundwater Sustainability Plan as required by the legislation before the January 31, 2022 deadline.

The Department of Water Resources (DWR) has developed a Strategic Plan for its Sustainable Groundwater Management (SGM) Program. DWR’s SGM Program will implement the new and expanded responsibilities identified in the 2014 Sustainable Groundwater Management Act (SGMA). Some of these expanded responsibilities include: (1) developing regulations to revise groundwater basin boundaries; (2) adopting regulations for evaluating and implementing Groundwater Sustainability Plans (GSPs) and coordination agreements; (3) identifying basins subject to critical conditions of overdraft; (4) identifying water available for groundwater replenishment; and (5) publishing best management practices for the sustainable management of groundwater.
