Sustainable Groundwater Management Act (SGMA)
The Sustainable Groundwater Management Act gives local public agencies (counties, cities, water agencies, PUDs) authority to manage groundwater locally, with State oversight. All high and medium priority groundwater basins must be managed under a Groundwater Sustainability Plan (GSP). The first step in the process is for the eligible local agencies to determine the make-up of the governance structure(s) in their groundwater basins. The governance agencies, known as Groundwater Sustainability Agencies (GSAs) can be a single entity managing an entire basin or a combination of Agencies.
In Colusa County, we have two groundwater basins that are subject to SGMA - the Colusa subbasin which, after basin boundary modifications have taken place, spans portions of Colusa and Glenn Counties, and the Butte subbasin which spans portions of Colusa, Glenn and Butte Counties.
In Colusa County, a multi-agency Groundwater Sustainability Agency was formed by the June 30, 2017 state-mandated deadline. The GSA, known as the Colusa Groundwater Authority, is a Joint Powers Authority with a 12-member board of Directors.
Although individual landowners are not eligible to be a GSA, it is important that they stay informed and engaged in the planning process. It is especially important for groundwater users that are not part of a water district (private pumpers) to participate in SGMA planning. All beneficial uses and users of groundwater (Water Code Section 10723.2) must be taken into consideration during SGMA planning and implementation. There will continue to be ample opportunities for public engagement during development of Groundwater Sustainability Plans. If you are not on the County’s SGMA email list, please email the Water Resources staff.
While we work within Colusa County political boundaries on SGMA planning, Staff continues to communicate planning activities with Yolo County, Glenn County, and each of the other four counties involved in the Northern Sacramento Valley IRWM region (Butte, Tehama, Shasta, Sutter).
You can find information and presentations from past meetings, as well as information on upcoming local meetings regarding SGMA at the Colusa Groundwater Authority’s website.
SGMA Meetings and Meeting Materials
The agencies that formed the Colusa Groundwater Authority, and other GSA-eligible agencies and interested parties met regularly to decide on the best SGMA governance structure for the Colusa County portions of the groundwater basins. You can find agendas, minutes and presentations from those early planning meetings below.
All agendas, minutes and meeting materials from Colusa Groundwater Authority meetings can be found on the CGA website

PAST PUBLIC MEETINGS:
PAST PRIVATE PUMPER ADVISORY COMMITTEE MEETINGS: The PPAC was made up of members representing the "white areas" of Colusa County. These are groundwater-dependent areas of the county that are not covered by a water agency, or other GSA-eligible agency. PPAC members were chosen by the Colusa County Groundwater Commission.

Colusa GSA Workgroup Documents
The Colusa County GSA Workgroup finalized the Joint Exercise of Powers Agreement Establishing the Colusa Groundwater Authority (PDF) (5/11/2017). The agencies forming the Colusa Groundwater Authority held public hearings in May and June to consider the adoption of a resolution approving the Joint Exercise of Powers Agreement Establishing the Colusa Groundwater Authority. The notice is ran in the Colusa Sun Herald Newspaper May 17, 2017 and May 24, 2017 (PDF).
