Corning Sub-basin Groundwater Sustainability Agency

The Corning Sub-basin Groundwater Sustainability Agency (GSA) governs the Glenn County portion of the Corning Subbasin.  Generally, the Corning Sub-basin GSA is bounded on the west by the Coast Ranges, on the north by Glenn-Tehama County boundary, on the east by the Sacramento River, and on the south by Stony Creek except for a small portion following the Glenn-Tehama County boundary.   Visit the Department of Water Resources SGMA Portal for GSA Formation information.
