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.
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.
