Supplementation Hatcheries

Hatcheries have operated in Washington State for more than a century, beginning with one hatchery on the Kalama River in 1895. Originally built to compensate for land use decisions that permanently altered large areas of fish-producing habitat, state hatcheries have since become an important part of the state's economy, releasing millions of fish annually for harvest by recreational and commercial fisheries. Tagging studies indicate that more than 75% of the salmon caught in Puget Sound and 90% of the salmon caught in the Columbia River originate from hatcheries, as do 88% of all steelhead.
