CA Water Plan Update at January 21st Water Commission Meeting

At the January 21, 2026, meeting of the California Water Commission, Department of Water Resources (DWR) staff will brief the Commission on the new era of the California Water Plan (Water Plan), which is being modernized following the passage of Senate Bill 72 in 2025. The final agenda and meeting materials are available on the Commission’s January 21, 2026 meeting webpage. Information on how to participate can be found here.

Senate Bill 72 (Caballero) directs DWR to consult with the Water Commission on the establishment of an advisory committee to inform the development of the 2028 update to the Water Plan. The 2028 update will usher in a new emphasis on setting and meeting quantifiable water supply goals. This builds on California’s Water Supply Strategy (2022), which outlined necessary actions for the state to adapt to a hotter, drier future where the changing climate leaves less water to meet California’s needs. The Water Supply Strategy included an interim statewide goal of increasing water supply by 9 million acre-feet by 2040. The 2028 update to the Water Plan will take that goal as a starting point.
