A California tribe has signed agreements with state and federal agencies to work together on efforts to return endangered Chinook salmon to their traditional spawning areas upstream of Shasta Dam, a deal that could advance the long-standing goal of tribal leaders to reintroduce fish that were transplanted from California to New Zealand more than a century ago and still thrive there.
Weeks after powerful storms dumped 32 trillion gallons of rain and snow on California, state officials and environmental groups in the drought-ravaged state are grappling with what to do with all of that water.
State rules say when it rains and snows a lot in California, much of that water must stay in the rivers to act as a conveyer belt to carry tens of thousands of endangered baby salmon into the Pacific Ocean.
Fishing groups and water suppliers fighting the Biden administration’s proposed drought rules for California’s water system told a federal judge Friday the emergency plans won’t stop the demise of endangered salmon.
With California trudging through another disappointingly dry winter, the federal government and state officials have agreed upon a set of temporary rules they claim are necessary to preserve enough cold water on the Sacramento River for Chinook salmon this spring and summer. The rules call for new water temperature targets and improved collaboration between federal and state officials on the management of California’s two main water conveyance systems.
Alarmingly low numbers of baby salmon are surviving their journey down the Sacramento River to the sea, confirming conservationists’ fears that low flows and high river temperatures during the drought would wipe out most of the endangered winter-run salmon born last year.
The California water board has approved a plan for water releases into the Sacramento River that could kill off an entire run of endangered chinook salmon and put at risk another population that is part of the commercial salmon fishery.
The State Water Resources Control Board has informed the federal Bureau of Reclamation it would accept its final plan for managing water flows from Shasta Lake into the Sacramento River, which is both the main source of water for Central Valley farms and the spawning habitat for chinook salmon. Because the bureau’s plan involves releasing water to irrigation districts earlier in the season, the river will be lower and warmer during salmon spawning season and could result in killing as many as 88% of endangered winter-run chinook eggs and young fish.
California’s salmon populations have been dangerously close to extinction for decades. A new partnership may help tip the scales toward recovery.
