Sustainable Groundwater Management Act (SGMA) Groundwater Sustainability Planning
The State of California under the Sustainable Groundwater Management Act (SGMA) law requires all groundwater well users to live under a Groundwater Sustainability Plan developed by Groundwater Sustainability Agencies that must be completed by January 31, 2022. This Plan will require all groundwater well use to be sustainable for all parts of the basins throughout California, and will potentially require meters and records on groundwater use. Also required will be a plan for recharging the aquifers if groundwater falls into an overdraft situation.
Development of the Groundwater Sustainability Plans by Groundwater Sustainability Agencies is just getting underway in Colusa and Glenn Counties.  Each groundwater user has the opportunity to help develop these Plans which all users will have to live by. It would behoove all groundwater users to get involved in this process.
Please attend Groundwater Sustainability Agency meetings and other local water management meetings including the Colusa Groundwater Authority, Glenn Groundwater Authority, and Colusa County Groundwater Commission meetings, and add your name to email notification lists. You can find more information and sign up for the email lists on the websites at:
