Every five years, the Sustainable Groundwater Management Act requires the GSAs to evaluate groundwater conditions, review whether the Groundwater Sustainability Plan is working as intended, and make changes as needed.

This workshop is an opportunity to hear what five years of monitoring show, understand the changes being considered, ask questions, and provide input. The Boards have not acted on the draft documents. Comments received will be considered before any Board decision.
