The federal government has proposed mandatory water reductions on the Colorado River for California, Arizona and Nevada, a move that would reshape water use across the West. The U.S. Bureau of Reclamation unveiled the plan Friday after years of stalled negotiations. The proposal marks the largest mandatory cuts in the river's modern history.
Under the proposal, the Lower Basin states could face collective cuts of up to 3 million acre-feet through 2036, "subject to hydrology," according to the Department of the Interior. That is roughly equivalent to the annual water consumption of more than 25 million people.
The 10-year federal framework would also permit annual releases from Lake Powell between 5 million and 12 million acre-feet. Water management decisions would be reviewed every two years, giving federal officials flexibility to adjust as conditions change.
Secretary of the Interior Doug Burgum called the framework a balance between flexibility and long-term negotiation. "This framework provides the flexibility to respond to changing hydrologic conditions while preserving the opportunity for the Basin States to continue working toward durable, consensus-based solutions," he said in a press release.
Lake Powell and Lake Mead, the nation's two largest reservoirs, have fallen to record levels this year after a record-dry winter across the West. The Colorado River supplies approximately 40 million people in seven states, tribal nations, Mexico, farms and industries.
Federal forecasts show Lake Powell could drop so low by the end of the year that turbines at Glen Canyon Dam would stop spinning. Those turbines generate electricity for homes, businesses and irrigation systems across the region.
The proposed cuts are the largest ever imposed on the Lower Basin. Urban water agencies would face higher prices, stricter conservation mandates and a greater need for groundwater. Agricultural producers would likely reduce output, idling land and potentially raising food prices.
Conservation measures that once seemed optional would become mandatory in many communities.
San Diego County depends on the Colorado River for a significant portion of its imported supply. The San Diego County Water Authority has invested in desalination, recycling and conservation, but the proposed cuts could still push water rates higher for residents in Del Mar and across the region.
The Colorado River stretches 1,450 miles and supports more than 40 million people. For decades, demand has exceeded supply. Climate change and rising temperatures have accelerated the decline, shrinking the river's flow well below historical averages. Negotiations among the seven basin states have stalled for years, prompting federal officials to step in.
The federal plan is expected to be finalized in the coming days. It offers a temporary fix, not a permanent solution. California, Arizona and Nevada must continue negotiating a long-term water-sharing agreement or face repeated federal intervention. For water users in Del Mar and across California, the message is clear: the era of abundant Colorado River water is over.
