The East Contra Costa Groundwater Sustainability Working Group is preparing a Draft Groundwater Sustainability Plan (Plan) and seeks input on Sections 3 and 4 of the Plan. The East Contra Costa Groundwater Subbasin is a medium priority subbasin, as determined by the State, and requires preparation of a Plan under the 2014 Sustainable Groundwater Management Act (SGMA). The Byron-Bethany Irrigation District (BBID) is a member of the Subbasin.

The Groundwater Sustainability Agencies received comments on Sections 1 and 2 of the Draft Plan during the summer of 2020. We are now asking for input on Sections 3 and 4 that discuss groundwater conditions, including a Hydrological Conceptual Model and historical, current and projected water supply. Sections 3 and 4 are found at the link below, or email and request the documents. Comments are due on Friday, January 15, 2021.
