ECOS and Habitat 2020 have submitted the following letter to the Sacramento Central Groundwater Authority regarding their application to the Sustainable Groundwater Management Grant Program. ECOS/Habitat 2020 look forward to participating with the Sacramento Central Groundwater Authority in the implementation of the Grant Proposal and the ongoing efforts to develop a Groundwater Sustainability Plan for the South American Subbasin in Sacramento County.
Ramon Roybal Assistant Engineer Sacramento Central Groundwater Authority 827 7th Street Room 301 Sacramento CA, 95814
Subject: South American Subbasin Prop 68 Round 3 Grant Proposal for Evaluating GDEs and Surface Water Depletions (Grant Proposal) Dear Mr. Roybal, The Environmental Council of Sacramento (ECOS) is a 501(c)(3) nonprofit organization working to achieve regional and community sustainability and a healthy environment for existing and future residents. ECOS member organizations include: 350 Sacramento, Breathe California Sacramento Region, Friends of Stone Lakes National Wildlife Refuge, International Dark-Sky Association, Physicians for Social Responsibility Sacramento Chapter, Sacramento Citizens’ Climate Lobby, Sacramento Electric Vehicle Association, Environmental Democrats of Sacramento County, Sacramento Housing Alliance, Sacramento Natural Foods Coop, Sacramento Audubon Society, Sacramento Valley Chapter of the California Native Plant Society, Sacramento Vegetarian Society, Save Our Sandhill Cranes, Save the American River Association, Service Employees International Union (SEIU) Local 1000 and the Sierra Club Sacramento Group. Members of Habitat 2020, a committee of ECOS, include: Friends of Stone Lakes National Wildlife Refuge, Friends of Swainson’s Hawk, International Dark-Sky Association Sacramento Chapter, Sacramento Area Creeks Council, Sacramento Audubon Society, Sacramento Valley Chapter California Native Plant Society, Save Our Sandhill Cranes, Save the American River Association, Sierra Club Sacramento Group and Sacramento Heron and Egret Rescue. We want to express our thanks for the opportunity to review and comment on the Sacramento Central Groundwater Authority’s (SCGA) Grant Proposal. We are very concerned about how the South American Subbasin’s (Subbasin) Groundwater Dependent Ecosystems (GDE) and Groundwater/Surface Water Interfaces (GWI) are identified, evaluated, and managed as part of SCGA’s development and administration of a Groundwater Sustainability Plan (GSP) for the Subbasin. We commend SCGA for opening its grant development process to include public comment. We are encouraged by this action and look forward to working with SCGA and the other Subbasin GSAs in implementing the grant’s workplan. In addition, in the coming months we look forward to working with all parties to develop a GSP for the South American Subbasin (SAS). We support the overall workplan proposed in the Grant Proposal. Specifically we endorse the workplan’s support for the completion of the numerical integrated groundwater surface water CoSANA model. We support the technical approach proposed for the identification and analysis of GDEs and GWIs. Finally, we support and commend SCGA for the identified efforts to include public input throughout the project. SCGA has included the potential formation of a Cosumnes Surface Water Group if such a group is found useful by those concerned and affected by decisions in the region. We see this group playing an important role in the analysis of the river basin and riparian forested areas and agricultural lands. We also endorse the workplan’s inclusion of and call for cross-basin coordination between each of the subbasins that share a river boundary Finally, we urge both the South American Subbasin and the Cosumnes Subbassin GSAs to work with their common stakeholders to establish the lower Cosumnes River basin as a “Management Area” under SGMA in each Subbasin’s GSP. This designation will allow the lower Cosumnes River basin’s critical resources to be managed effectively. ECOS/Habitat 2020 look forward to participating with SCGA in the implementation of the Grant Proposal and the ongoing efforts to develop a GSP for the Subbasin. Sincerely, Rob Burness and Sean Wirth, Co-chairs of Habitat 2020
The South American Subbasin is located in the central portion of Sacramento County. It is primarily managed by the Sacramento Central Groundwater Authority (SCGA).
ECOS believes that Sacramento Central Groundwater Authority’s understanding of the hydrology of the Subbasin should be measurably improved, and we have written a letter suggesting some ways to achieve that. Below is an excerpt of our letter.
The Environmental Council of Sacramento (ECOS) notes with interest the Sacramento Central Groundwater Authority (SCGA) Board’s September 12, 2018 direction to Staff to evaluate the State of California’s C2VSimFG model input data for the South American Subbasin (Subbasin) and update the State’s model data as necessary. We believe that SCGA’s understanding of the hydrology of the Subbasin should be measurably improved. SCGA should look to the modeling and monitory efforts underway by the Regional Water Authority and the Sacramento Groundwater Authority (SGA), and adopt and put in place a comprehensive and compatible monitoring program for the Subbasin.
We also believe the Board acted with imprudence when it recently adopted its operating budget for the upcoming year, in that, among other issues, the Board did not provide enough funding for groundwater monitoring and modeling. SCGA’s existing set of monitoring wells is insufficient to provide a full understanding of the flows of groundwater into, through and out of the Subbasin. Semiannual data points are not sufficient to understand and effectively manage the Subbasin. While we commend SCGA’s recent effort to provide real time monitoring in a small, select group of wells, we believe you should do far more in this important area.
