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.

Sacramento Region Supports Governor’s Call for Conservation

July 8, 2021

ECOS, as a Water Forum signatory, is working in concert with all of the Forum members to address the current drought. Unfortunately higher temperatures and periods of drought are increasing in the Sacramento region and we have to prepare for them. The following press release has some important water saving actions you can take and here is another one that will contribute to our current drought situation and the future impacts of climate change as well:

Begin the transition to a beautiful, low-water landscape in your home, business, or public space by removing half of the turf grass this summer. For every one thousand square feet of lawn removed, 90 gallons of water is conserved each time that lawn would have been watered. Now you are ready to add low-water, local native plants and drip irrigation this coming winter. The California Native Plant Society website has information on how to remove your lawn, lists of local native plants that fit your needs and landscape conditions, and tips on how and when to plant them. If you have trees in the lawn area being removed, don’t forget they will still need to be watered.

Landscaping while very important for all of us is a major source of water use. We want beauty and shade in our outdoor spaces; and insects, birds, and animals depend on the plants we choose to survive. Local native plants not only save water, they significantly contribute to the beauty of our region and are critical and highly desirable habitat for local insects, birds and animals.

Ralph Propper, Board President, ECOS

Sacramento, Calif. – The following statement was issued today by Jessica Law, Executive Director of the Water Forum, and Sean Bigley, Board Chair of the Regional Water Authority, in response to Gov. Gavin Newsom’s Proclamation of a Drought State of Emergency, expanding the emergency to nine additional counties, and asking the public to voluntarily conserve 15 percent.

“The Governor’s announcement today underscores the severe drought conditions throughout California and in the Sacramento region.

“Sacramento-area leaders across the region’s major municipalities yesterday issued a news release imploring the public to increase their conservation efforts, and we support the Governor’s call for a voluntary 15 percent reduction.

“We understand that the public has continued to conserve since the last drought, and we applaud those efforts. Now, we are asking residents to do more. Increasing conservation this summer will help the environment of the Lower American River and decrease the potential for water shortages in 2022 if drought conditions persist.

“There are many easy and quick water-saving actions that can be taken today, such as dialing back sprinklers by two minutes (while continuing to water your trees), making sure sprinklers and drip irrigation run in the morning, adding mulch to conserve moisture and fixing household leaks.

“Also, there’s never been a better time to take advantage of the many rebate programs available to help with downsizing or replacing a thirsty lawn with beautiful low-water plants or upgrading to efficient irrigation and fixtures.

“You can find more water-saving tips, information about rebates and landscape watering guidelines at BeWaterSmart.info.”

The Sacramento Water Forum is a diverse group of business and agricultural leaders, citizen groups, environmentalists, water managers and local governments working together to balance two co-equal objectives: to provide a reliable and safe water supply for the Sacramento region’s long-term growth and economic health; and to preserve the fishery, wildlife, recreational, and aesthetic values of the lower American River.

The Regional Water Authority (RWA) is a joint powers authority representing 20 water providers serving 2 million people in the greater Sacramento region. Formed in 2001, its primary mission is to help its members protect and enhance the reliability, availability, affordability and quality of water resources. Learn more at rwah2o.org.
