Solano County cities warn of water supply crisis due to state flow management changes

The State Water Resources Control Board convened on December 12, 2024, to discuss critical updates regarding the Bay-Delta water management strategies. The meeting focused on the implications of unimpaired flow regulations on municipal water supply systems, particularly for cities reliant on the Solano project.

The discussion began with concerns raised about how the proposed regulatory framework could significantly reduce water supply and reliability for municipalities such as Vallejo, Benicia, Fairfield, Vacaville, and Suisun City. Stakeholders emphasized that the staff's approach could lead to drastic cuts in water availability, impacting urban water management plans, especially during dry and drought years.

Key points of contention included the level of authority granted to State Board staff, which critics argue could lead to unilateral decisions affecting water rights without adequate oversight or public participation. Specific regulatory provisions were highlighted, including the ability of staff to modify deadlines for unimpaired flow objectives, compliance points, and various management plans related to temperature and reservoir storage. These actions, stakeholders warned, could occur without proper notice or due process, further jeopardizing municipal water supplies.

Additionally, the meeting addressed the potential effects of unimpaired flows on Puna Creek, noting that the current regulatory approach fails to consider existing adjudicated rights and the structures established by the Pouda Creek Accord. This oversight raises concerns about compliance with water quality objectives outlined in California's water code.

In conclusion, the meeting underscored the urgent need for a balanced approach to water management that considers both regulatory objectives and the practical needs of municipalities. Stakeholders called for greater transparency and involvement in decision-making processes to ensure that water supply reliability is maintained for urban areas in Solano County. The board is expected to continue discussions on these issues in future meetings, with a focus on finding solutions that align regulatory goals with community water needs.
