About 3 million young Chinook Salmon were spawned and then released into the wild Monday.

Raised at the Nimbus Hatchery for 6 months these fish will swim 100 miles or so all the way to the San Francisco Bay. They will live for two or three years out in the ocean, and hopefully make their way right back to the Nimbus Hatchery.

Out of all the fish released today, it’s estimated that only 2% will make it back to spawn.
