California is considering the first major rewrite of Bay-Delta water rules in decades, with proposed changes to how much water must remain in rivers and giving regional water agencies more flexibility in how they comply with those limits. The plan has divided stakeholders, with environmental and tribal groups calling for stronger safeguards, while water agencies welcome the added flexibility but want looser flow rules.

Why it matters

The Bay-Delta is a crucial water source for California, supplying drinking water to millions and supporting important ecosystems. How the state manages water flows and quality in the region has major implications for the environment, agriculture, and urban water supplies across the state.

The details

The proposed plan would let water agencies opt into a new 'Healthy Rivers and Landscapes' program, under which they would follow a negotiated package of timed water releases, habitat restoration, and monitoring, rather than just meeting fixed flow targets. Critics argue this could weaken enforceable safeguards, while agencies say the proposed flow rules would drain reservoirs too early and increase river temperatures, harming fish. The state water board is holding hearings this week but will not take final action until a later date.

  • The State Water Resources Control Board is holding a three-day hearing on the proposed Bay-Delta plan this week, concluding on Friday, January 31, 2026.
  • The board will accept written comments through Monday, February 3, 2026 before considering final action on the plan at a later, publicly noticed meeting.

What they’re saying

“We need better benchmarks so that if (the plan) fails, you can act expeditiously.”

— John McManus, Golden State Salmon Association

“The proposed update prioritizes water districts and wealthy agricultural interests over the Board's obligations to uphold the Public Trust Doctrine and protect water quality for the Tribes and communities that depend upon Delta waterways.”

— Morgen Snyder, Director of policy and programs, Restore the Delta

“Not only does the staff proposal significantly impact Sacramento region's water supply, but it's actually detrimental in the long term to threatened species on the lower American River like steelhead and for all salmonoids.”

— Andy Fecko, General manager, Placer County Water Agency

What’s next

The State Water Resources Control Board will consider final action on the Bay-Delta plan update at a later, publicly noticed meeting after reviewing written comments submitted by February 3, 2026.

The takeaway

The proposed update to California's Bay-Delta water rules has sparked a divisive debate, with environmental groups and tribes calling for stronger protections, while water agencies seek more flexibility. The outcome will have far-reaching impacts on the state's water supply, ecosystems, and the communities that depend on this crucial water source.
