Although most hatchery lands and outdoor spaces have remained open for the public to enjoy, we ask that you Recreate Responsibly.

  • Check local conditions on this website and called for current information. Operations vary based on local public health conditions.
  • • The CDC recommends all individuals wear a mask indoors in public in areas of substantial or high transmission. Recognizing that most of the United States is currently in substantial or high transmission categories and to best protect visitors and our staff, we've implemented a nationwide mask requirement. Masks are now required inside all U.S. Fish and Wildlife Service buildings, regardless of vaccination status or location. All people, regardless of vaccination status, are required to wear a mask on all forms of public transportation and in healthcare settings on DOI lands.
  • Most importantly, stay home if you feel sick and continue to watch for symptoms of COVID-19 and follow CDC guidance on how to protect yourself and others.

  • Dworshak National Fish Hatchery is currently closed to the public.

Dworshak NFH Transition Update

Since 2005, Dworshak National Fish Hatchery has been jointly managed and operated by the Nez Perce Tribe and the U.S. Fish and Wildlife Service, pursuant to Congressional authorization. The Hatchery is located on the Nez Perce Reservation, is owned by the U.S. Army Corps of Engineers, and was built to mitigate for the construction of Dworshak Dam on the North Fork Clearwater River. As joint managers, the Tribe and the Service have successfully raised fish together at the Hatchery for over 16 years. The Tribe and Service, in collaboration with the Corps, are now evaluating the transition of all fish production responsibilities and associated staffing at the Hatchery to the Tribe. The Service would continue to provide administration services, public outreach, fishery research, and fish health monitoring at the Hatchery. These changes would not affect the Congressionally authorized fish mitigation production targets and requirements and would be budget neutral.


Destroy! Don’t Dump! Invasive zebra mussels were recently found in "moss balls,” an aquarium plant product sold at aquarium and pet supply stores.

Zebra mussels are regarded as one of the most destructive invasive species in North America.

If you have moss balls in your aquarium, follow these Disposal Instructions to keep our waterways safe.
