The current mission of the Hatchery is to provide four million Lewis Lake lake trout eggs to the Great Lakes restoration effort, and to provide 3.5 million Plymouth Rock brown trout eggs to other Federal, state and tribal programs. The Hatchery maintains the back-up broodstock for the McConaughy rainbow trout. We are also involved in rearing and breeding the endangered Wyoming toad for reintroduction into the wild.

They are open year round, seven days a week, from 8:00 a.m. until 4:00 p.m. and provide guided group tours upon advanced request. Fish spawning activities can be observed from the end of September through October.
