Tacoma Power operates two large fish hatcheries on the Cowlitz River, the Cowlitz Salmon Hatchery and the Cowlitz Trout Hatchery. Tacoma Power’s Cowlitz Salmon Hatchery includes an award-winning education center. Inside the visitor center, interactive displays show a salmon’s journey through life, exploring the 5 “Hs” of a salmon’s life cycle – hatchery, hydropower, harvest, habitat, and high seas. The salmon hatchery produces nearly 13 million fish each year, including about 1.3 million spring Chinook, 5.0 million fall Chinook, and 2.4 million coho salmon.
