Salmon seen in California's North Yuba River for first time in almost a century
Several months after the start of a pilot program aiming to restore salmon runs in California’s Sierra County, Chinook salmon can be found in the North Yuba River “for the first time in close to a century,” the California Department of Fish and Wildlife announced on Thursday.
The salmon are a result of a project studying the return of spring-run Chinook salmon to their native spawning habitat in the Sierra Nevada, the department said. The eggs that the fish hatched from were deposited in October along a 12-mile stretch of gravel riverbed in the North Yuba River east of Downieville in an effort to mimic the spawning behaviors of wild salmon.
Young fish were first seen on Feb. 11 in a rotary screw trap installed several miles downstream from where the eggs were implanted, according to CDFW. The fish are being trucked downstream to the lower Yuba River, where they will then continue their migration to the ocean.
