Returning salmon to San Joaquin River will cost millions
Project includes $14.5M hatchery near Friant Dam

FRESNO -- Reviving chinook salmon on the San Joaquin River will cost more than $20 million — which may sound like a lot of money for 40,000 fish. But this rare project will take years of work, scientists say.
Three-quarters of those fish will be spring-run salmon, a threatened species already in danger of extinction in California. In the San Joaquin, the fish will have to survive in the southernmost salmon fishery on the continent — where the water sometimes gets a little too warm for them.
Scientists say they haven't found similar reintroductions of the threatened spring-run salmon in a river such as the San Joaquin, which had been dry in places for more than a half-century. Federal officials need to breed a resilient fish for this river.
Last month, federal officials began revealing details of the project that will include a $14.5 million hatchery near Friant Dam east of Fresno and more than $7 million to operate it for a decade.
The total is a small slice of the restoration cost, which could run as high as $1 billion.
Farm critics say it would be cheaper to skip the expense of salmon restoration and just allow other fish, such as trout and blue gill, to populate the river.
"I think the river should be restored, but not with salmon," said farmer Kole Upton.
The salmon runs — which died after Friant Dam was built in the 1940s — are required by the settlement, signed by farm officials, environmentalists and the federal government in 2006. Salmon played a central role in the environmental lawsuit to restore the San Joaquin River.
Federal officials say the hatchery will allow them to raise populations of federally protected spring-run salmon and protect the Northern California donor rivers providing the fish.
"You can't just collect 1,000 adult fish, so we will focus on getting small numbers of young and eggs from several places," said biologist Kim Webb with the U.S. Fish and Wildlife Service.
The project is part of a San Joaquin River restoration that began with experimental water releases from Friant Dam in October 2009. About 150 miles of the San Joaquin will be restored between Friant and the Merced River confluence.
In the next few years, federal officials will have to decide whether to run the restored river through flood bypasses or rebuild a section of river that has almost completely disappeared.
