New Groundwater Sustainability Agency Websites!

The three Groundwater Sustainability Agencies (GSAs) in Sonoma County continue to work hard to make sure the community has access to GSA documents, information, and meeting materials. We want to make sure you are informed and have the best information possible – and, of course, we want to make it easy for you to share your thoughts, concerns, and feedback with your GSA.

To make this happen, staff have set up individual websites for the three GSAs. We hope that these reorganized, basin-focused websites will help you find exactly the information you need. Click your basin on the map or one of the buttons below to visit the website for your GSA.
