California Approves Contested Delta Water Plan

The California State Water Resources Control Board voted 4-1 on October 29 to adopt a plan that changes how water agencies can draw from the Sacramento-San Joaquin Delta and waterways that flow into it. The Delta supplies water to about 30 million people and 4 million acres of farmland, while its native fish populations have declined. The previous major update for much of the watershed dated to 1995.

Under the eight-year plan, agencies can make voluntary agreements to provide river flows and fund habitat restoration. Officials say participating agencies have pledged $2.9 billion and work covering more than 20,000 acres of floodplain and 5,000 acres of tidal wetlands. The board will assess progress annually, and can apply traditional mandatory rules if an agency fails to meet its commitments.

The plan’s supporters, including the Metropolitan Water District of Southern California, say it can support reliable water supplies while helping wildlife. California Natural Resources Secretary Wade Crowfoot described the approach as a major shift in how the state manages the Delta.

Opponents from environmental, fishing and tribal groups argue the agreements will allow excessive pumping and put threatened fish at greater risk. Some water agencies also say the adopted terms are more restrictive than the deal they originally supported.

The Trump administration has said the federal Bureau of Reclamation will not participate unless the plan changes, putting federal aid worth several hundred million dollars at risk. Westlands Water District has also said it plans to leave the program. The board’s approval leaves the state facing questions about whether the voluntary approach can proceed without those participants.
