Several fishing and conservation organizations brought a federal complaint Monday over the harm they expect to befall an already threatened species of fish from the Trump administration’s efforts to set new rules for the operation of major California water projects.

Led by the Pacific Coast Federation of Fishermen’s Associations, the groups claim that the government’s biological assessments of the Central Valley Project and State Water Project were politically motivated and failed to consider proper environmental protection standards. They filed their suit in U.S. District Court for the Northern District of California.
