The Groundwater Sustainability Agencies strive to develop a single Groundwater Sustainability Plan for the Corning Subbasin. The agencies have submitted a Notice of Intent to Develop a Groundwater Sustainability Plan for the Corning Subbasin to the Department of Water Resources. A written statement was also developed and distributed as required by Water Code Section 10727.8.
