The struggle over management of water supplied through the Sacramento-San Joaquin Delta continues as the Biden administration seeks a reversal of rules put in place by agencies under the Trump administration.

Last week, the U.S. Bureau of Reclamation sent a letter to federal fisheries agencies and announced it is reinitiating consultation of the U.S. Fish and Wildlife Service and National Marine Fisheries Service 2019 biological opinions related to the coordinated, long-term operation of the Central Valley Project and State Water Project.

The two water projects are California’s primary water-delivery systems that guide pumping of water through the Sacramento-San Joaquin Delta, sending water south to tens of millions of people and to millions of acres of farmland.
