“Local Agencies will now have the power to assess the conditions of their local groundwater basins and take the necessary steps to bring those basin in a state of chronic long-term overdraft into balance.”
-Governor Edmund G. Brown, Jr.From the letter accompanying the signing

Commits the State to locally controlled sustainable groundwater management 50 Year Implementation PeriodHistory AB3030 (1990), SB 610/221 (2004)
SGMA Applies to 127 High and Medium Priority Groundwater Basins
96% of Total Groundwater Use in CA40% Normal Annual Use of Water in CA>60% During Drought Periods
The Role of the Groundwater Sustainability Agency and the
