Visitors in October or late March to early April can see salmon jumping the fish ladder. You can also watch the spawning process, where eggs are taken from female fish and fertilized by male fish. Each year, this hatchery produces more than 2 million fingerlings (young fish 3-5 inches long) and close to 1 million yearlings (fish one year old or over).
