It’s one of the first adult salmon to return in more than 65 years. By Before the construction of Friant Dam and creation of Millerton Lake in 1942, the San Joaquin River was a historic spawning habitat for spring-run Chinook salmon. But it’s been more than 65 years since adult salmon returned from the Pacific Ocean to the river – until this month, that is.
