A federal lawsuit claims California and federal water managers are harming several fish species with water allocations.
A coalition of four groups, including Restore the Delta, filed the lawsuit in federal court.
The lawsuit claims two federal agencies and the California State Water Resources Control Board and Department of Water Resources violated federal and state water laws.
It alleges several fish species in the Delta and Chinook salmon runs on the Sacramento River are near extinction.
Barbara Barrigan-Parrilla is with Restore the Delta.
