The Colusa Groundwater Authority (CGA) and Glenn Groundwater Authority (GGA) (Agencies) will host a pair of public workshops about local groundwater conditions and areas of concern in portions of Colusa and Glenn Counties. Both workshops will cover the same material. Groundwater in the two counties is regulated by the CGA and GGA respectively as per the Sustainable Groundwater Management Act (SGMA). The entire area managed by the Agencies is titled the “Colusa Subbasin” by the California Department of Water Resources, and the Agencies are required to work together to address groundwater problems in the Subbasin. Groundwater conditions that are not sustainable will be subject to a range of future solutions and if these local Agencies are not successful addressing these challenges, the State of California can take over groundwater management in the Subbasin. The Boards of the Agencies are committed to maintain local control of groundwater and regularly update stakeholders about Subbasin conditions and future Agency decisions.

The workshops will provide a brief overview of SGMA and Groundwater Sustainability Plan  requirements. Each will then focus on up-to-date, technical information about groundwater conditions and related topics with a focus on sustainability issues in the Colusa Subbasin. Stakeholders will have time to ask questions to Agency Directors, staff, and the technical consulting team. The public is encouraged to attend to learn more about SGMA and the Agencies’ next steps. The public will also learn about the importance of Stakeholder participation during Groundwater Sustainability Plan development, and how they can be involved in the process. 

“We will have some tough decisions to make in the future” said Supervisor Denise Carter, Chair of the CGA. “We are committed to share everything we know about this Subbasin’s groundwater and then develop a program to protect this critical resource”.

Similarly, Leslie Nerli representing Glide Water District on the GGA said “We have to hear from our neighbors. This is a big deal.  We’re going to make decisions soon that will affect groundwater management for the next 20 years.  We may not like it but we have some tough challenges in this basin and we need folks to come to the meeting and help provide information to make some of these decisions”.
