On its face, SGMA appears to promise comprehensive groundwater management. The legislature sought to “provide for the sustainable management of groundwater basins”. SGMA therefore “applies to all groundwater basins in the state”…. DWR has ranked only 18 percent (94 out of 515) of Bulletin 118 groundwater basins as medium or high priority, although these basins account for virtually all of current groundwater pumping in the state. The result is a fragmented regulatory system that leaves significant gaps in the sustainable management of California’s groundwater.
