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.
California water projects have pushed winter-run chinook salmon into the single place that remains suitable for them to breed: the reservoir behind the Shasta Dam.
Even that sanctuary fails during drought years as the same pressures that drove salmon into the reservoir — too little water and too much heat — take hold in their only breeding ground. Climate change is making those pressures worse, and the chinook population is closer than ever to extinction, according to NOAA Fisheries.
