Brought before the Inyo County Superior Court against LADWP by the Mammoth Fly Rodders in 1984 and later joined by the MLC, NAS, and California Trout (Cal Trout). The suit charged that LADWP's diversions violated the Public Trust Doctrine, California Fish and Game codes, and the California Environmental Quality Act (CEQA). In 1984 the court issued a temporary restraining order requiring LADWP to release 19 cubic feet per second (cfs) into lower Rush Creek. In 1985, the Mono County Superior Court issued a preliminary injunction that required LADWP to continue to release a flow of 19 cfs into Rush Creek to protect public trust resources.
