Under a new order issued by the State Water Resources Control Board (State Water Board), persons claiming senior water rights in the Sacramento-San Joaquin Delta watershed will be required to provide detailed information on the water rights they claim and diversions associated with those rights. The order comes after the State Water Board received complaints from the California Department of Water Resources and the U.S. Bureau of Reclamation, both holding junior water rights, that some riparian and pre-1914 water right holders may be illegally diverting stored water in the Sacramento and San Joaquin watersheds and the Delta.
The order applies to 1,061 water rights claims held by about 450 individuals in the Delta and the Sacramento and San Joaquin watersheds. The order can be accessed here.
