Status of the Cosumnes Groundwater Subbasin 7/27

Thursday, July 27, 2023

Presentation/Discussion of the Status of the Cosumnes Groundwater Subbasin and Related Matters 6:10 – 7:10 by Austin Miller, Sloughhouse RCD Executive Director

The ECOS Water Committee invites you to join us in a presentation/discussion of the sustainability of the Cosumnes Groundwater Subbasin (CGA). This subbasin is the source of groundwater providing a significant amount of the water used by agriculture, rural residents, and small urban areas in the south county and western portions of Amador County that are located south of the Cosumnes River.

Austin Miller, Executive Director of the Sloughhouse RCD coordinates the management of the subbasin and will present the latest condition of the subbasin as reflected in the annual subbasin sustainability report recently submitted to the state. Austin will also brief us on interactions with the other subbasin GSAs, neighboring subbasins, and the Regional Water Authority on the development of a Regional Water Bank. Finally, Austin will discuss the ability of the Cosumnes Subbasin Groundwater Sustainability Agencies to implement the Subbasin’s Groundwater Sustainability Plan (GSP) given the loss of grant funds and other limitations and what is planned to deal with these impediments. The effective implementation of the GSP is made more important given plans by local water purveyors to expand conjunctive use, the Regional Water Authority’s plan to operate a Regional Water Bank in the North and South American Subbasins, and the potential impacts these activities may have on the sustainability of the Cosumnes Subbasin. Bring your questions and be prepared for a thoughtful presentation and discussion.

Comments on the North American Subbasin draft Groundwater Sustainability Plan

On October 14, 2021, ECOS and Habitat 2020 submitted comments on the North American Subbasin (NASb) draft Groundwater Sustainability Plan (GSPD).

ECOS commends the effort of the North American Subbasin Groundwater Sustainability Agencies (GSAs), and their consultants, for involving the public and in preparing the GSPD. The GSPD provides both a technical and lay understanding of the North American Subbasin (NASb) and how groundwater moves within it. The GSPD is an important reference document that brings together a wealth of information in one place. With additional information, projects and management Actions recommended below, the GSPD will present a clear direction for the subbasin’s sustainable groundwater management.
