The ruling in a Fresno federal court Friday ultimately could force regulators to change the way they move and use water to help endangered salmon spawn in the state's rivers and swim downstream into the Pacific Ocean.
Environmentalists and fishermen had asked the judge to order immediate protections for the fishes' habitat, arguing that the collapse of one of the West Coast's biggest wild salmon runs earlier this spring foretold the extinction of related species.
U.S. District Judge Oliver Wanger denied the groups' request to release more water from a federal reservoir to help young endangered winter-run Chinook salmon reach the ocean. That could have left hundreds of acres of almonds, walnuts and tomatoes without irrigation supplies next month, at the height of California's drought.
"I'm on cloud nine here," said Jeff Sutton, who manages a canal system that delivers water to farms from near Redding to just north of Sacramento. "We're obviously ecstatic that the service area is going to continue to finish the irrigation season and be able to harvest the crops."
Still, the battle is far from over.
The judge's ruling established that the canals and pumps that deliver water to 23 million Californians are causing "irreparable harm" to two salmon species, as well as the threatened Central Valley steelhead. The second salmon population, the Central Valley spring-run Chinook, is on the federal list of threatened species.
On Wednesday, attorneys for federal and state regulators, farmers, environmentalists and fishermen are scheduled to meet in Wanger's courtroom to discuss how to protect the fish for the next nine months, while federal biologists rewrite their plan to operate water projects tied to the Sacramento-San Joaquin Delta.
