Ripple on water

On Thursday, January 26, 2023, the California Department of Water Resources announced approval of all three local groundwater sustainability plans (GSPs): Santa Rosa Plain, Sonoma Valley and Petaluma Valley.

Local groundwater sustainability agencies (GSAs) are implementing plans consistent with the requirements of the Sustainable Groundwater Management Act (SGMA), California’s landmark groundwater management law enacted in 2014.

The GSPs assess the conditions of the groundwater basins, analyze the basins’ sustainability over a 50-year period, and identify projects and actions needed to ensure the basins are sustainable by 2042.
