Key takeaways

? The Trump administration plans to increase water deliveries from the Sacramento-San Joaquin Delta to Central Valley farmlands, aiming to support agriculture and communities, potentially adding 250,000–400,000 acre-feet annually.

? California officials warn the plan threatens fish populations, could reduce water for millions, and undermines decades of state-federal cooperation on water management.

? Critics highlight risks to Chinook salmon, steelhead trout, and Delta smelt, arguing the plan weakens protections and may compromise the ecosystem and sustainable water supply.

Acting on an order from President Trump, the federal government on Thursday announced plans to pump more water to Central Valley farmlands from the Sacramento-San Joaquin River Delta, a unilateral action that California officials warned could threaten fish and reduce the amount of water available for millions of people in other parts of the state.

The U.S. Bureau of Reclamation said in a statement that its update of the operation plan for the federally operated Central Valley Project aims to "maximize water deliveries across California while maintaining protections for endangered fish species." The revised plan will increase water deliveries to farmlands and communities across the San Joaquin Valley.
