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.

Local Groundwater Sustainability

On September 8, 2021, ECOS and Habitat 2020 submitted a letter regarding the Groundwater Sustainability Plan of the South American Sub-basin (SASb), just south of the American River.

Background

Climate change in the Sacramento region requires innovation to deal with more extremes in precipitation. In wetter years, we should pump water into groundwater basins so that we can pump it out during drier years. Just south of the American River is the South American Sub-basin (SASb) that we agree should be used this way. The SASb Groundwater Sustainability Plan includes a Sustainable Yield value – the amount of groundwater that can be extracted annually from the SASb while maintaining it at a sustainable level. This letter provides comments on how the draft Groundwater Sustainability Plan develops the Sustainable Yield level and proposes management actions that should be taken to ensure the SASb’s Sustainable Yield is maintained in the future.
