The fish ladder at the California Department of Fish and Wildlife’s Feather River Hatchery in Oroville opened on September 19, heralding the start of the spawning season on the Feather River.
As the hatchery spawns spring-run Chinooks, anglers are experiencing increasing salmon success on the section of river open to fishing.
The hatchery spawns both spring-run and fall-run Chinook salmon. The staff will take more than 3 million spring-run eggs and 12 million fall-run eggs over the next two months in order to produce Chinook salmon for release next spring, according to Penny Crenshaw at the hatchery.
The hatchery has trapped around 1,000 spring-run Chinooks and has taken 2.8 million eggs to date, according to a preliminary estimate. They will begin spawning the fall-run Chinooks around October 10.
Once the young salmon reach 2 to 4 inches in length, 100 percent of the spring-run stock and 25 percent of the fall-run stock will be adipose fin clipped and implanted with coded wire tags prior to release, according to Crenshaw. CDFW biologists use the information from the tags to chart the survival, catch and return rates of the fish.
Visitors can observe the salmon through the viewing windows and from the observation deck located at the base of the fish barrier dam. At the main side of the hatchery, visitors can observe CDFW technicians performing the spawning process.

There are eight state-run salmon and steelhead hatcheries, all of which will participate in the salmon spawning effort, according to the CDFW. Those hatcheries, along with federally run hatcheries, will be responsible for the release of 40 million juvenile salmon into California waters this season. These massive spawning efforts were put in place over the last 50 years to offset fish losses caused by dams that block salmon from historic spawning habitat.
