Kooskia National Fish Hatchery, authorized by Congress in August 1961, was established to rear spring chinook salmon for release into the Clearwater River basin. Construction of the hatchery was started in 1966. Fish production, begun in 1969, established runs of adult spring chinook salmon returning to Clear Creek. Smolts released from the hatchery return 2-3 years later as 7-20 pound adults. The hatchery is located 1.5 miles southeast of Kooskia, Idaho near the confluence of Clear Creek and the Middle Fork Clearwater River.
In 2007, the certification of the Snake River Basin Adjudication settlement included transfer of hatchery management to the Nez Perce Tribe, who are responsible for day-to-day fish production, supporting the goal to raise and release up to 600,000 juvenile Spring Chinook salmon annually.
