The Trinity River Hatchery was built to make up for hundreds of miles of salmon and steelhead spawning habitat that was lost as a result of the Trinity and Lewiston Dam projects. Species raised are fall and spring Chinook salmon, coho salmon and winter steelhead trout. Brown trout were raised in the late 1960's but stocking was discontinued.
