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.

Sustainability of the South American groundwater subbasin 6/28

The ECOS Water Committee invites you to join us on June 28 from 6:00 until 7:00 to take part in a presentation/discussion of the sustainability of the South American groundwater subbasin. This subbasin is the source of groundwater providing a significant amount of the water used by the urban areas and agricultural areas south of the American River. John Woodling, Executive Director of the Sacramento Central Groundwater Authority (SCGA), the agency that coordinates and manages a major portion of the subbasin, will be presenting the latest condition of the subbasin as reflected in the annual subbasin sustainability report recently submitted to the state. He will also describe efforts to protect Groundwater Dependent Ecosystems, shallow wells, and improve the subbasin’s monitoring and modeling programs. All of these actions are important given the plan by the Regional Water Authority to operate a water bank in the area overseen by SCGA. We are all interested to learn how SCGA plans to interact with the proposed Regional Water Bank. Bring your questions and be prepared for a thoughtful presentation and discussion.

Local Water Issues: Sustainability of the North American Groundwater Subbasin 5/24

The ECOS Water Committee invites you to join us on May 24 from 6:00 until 7:00pm to take part in a presentation/discussion of the sustainability of the North American groundwater subbasin. This subbasin is the source of groundwater providing a significant amount of the water used by the urban areas north of the American River. Jim Peifer Executive Director of the Sacramento Groundwater Authority (SGA), the agency that coordinates and manages a major portion of the subbasin, will be presenting the latest condition of the subbasin as reflected in the annual subbasin sustainability report recently submitted to the state. He will also describe efforts to protect Groundwater Dependent Ecosystems, shallow wells, and improve the subbasin’s monitoring and modeling programs. All of these actions are important given the plan by the Regional Water Authority to operate a water bank in the area overseen by SGA. Bring your questions and be prepared for a thoughtful presentation and discussion.

For more information on areas of interest regarding the North American Subbasin please see the Water Committee’s letter of invitation to SGA.

Sacramento Region’s Water Future 3/29

At the ECOS MTG/Board on March 29, 2023, join us for a presentation, Sacramento Region’s Water Future.

Jessica Law, Executive Director of the Sacramento Water Forum and Ashlee Casey, the Forum’s Senior Engineer are joining the ECOS membership and guests on March 29 at 6:00 pm to present and discuss the results of a Water Forum Ad Hoc Technical Team GAP Analysis Report. This Report is an important step in the Water Forum’s efforts to revise the current Water Forum Agreement to accommodate the Region’s anticipated water demand growth and potential impacts from a changing climate. Ashlee managed the staff and consultant effort to develop the Report. Jessica and Ashlee will describe the findings of the report including the significant changes in Northern California hydrology brought about by the increasing temperatures that are projected to occur over the next decades. These warmer temperatures and shifting global conditions will cause longer and more frequent droughts and will shift the region’s runoff pattern earlier in the season. Coupled with planned increases in water use, our region will likely experience significant water management and environmental challenges.

Some of the Report’s findings indicate that the greater Sacramento area’s future water supply reliability will be reduced as the result of both planned growth and increasing temperatures caused by climate change. These rising temperatures will reduce the “snowpack reservoir” and increase the probability that in some years Folsom Reservoir will be at or near deadpool conditions. Surface water modeling of these impacts indicates lower flows in the Lower American River that will affect our ability to preserve the fishery, wildlife, recreational, and aesthetic values of the lower American River causing the region’s salmonid species to encounter near‐fatal or fatal conditions in many years primarily due to higher water temperatures.

Completion of the GAP Analysis Report is a significant step in the Water Forum 2 negotiation process. Water Forum members are beginning work on discussions and proposed actions for a new Water Forum Agreement to address the issues described in the Report. Jessica will provide insights into some of the areas the Water Forum members are discussing, and the process being used by the Forum to reach agreement on a new Water Forum Agreement 2. One that provides a roadmap for the region’s water future.

Join us on March 29 at 6:00 pm to learn about the GAP Analysis Report findings. Bring your questions and suggestions on what we should do to provide a reliable and safe water supply for the region’s economic health and planned development through 2040 and beyond; and preserve the fishery, wildlife, recreational, and aesthetic values of the lower American River.
