• Hatchery infrastructure rapidly developed into the 1900’s

• By 1910, over 550 million salmon and steelhead had been released into the Columbia Basin

• Over 8.3 Billion S&S released since 60’s

• YKFP- one of few programs evaluating how a production scale salmon program affects other fish species
