Coronavirus Update

Stocking Update September 18, 2020:  During the COVID19 pandemic, the Willow Beach National Fish Hatchery will continue to stock rainbow trout in the and around the Willow Beach National Recreational Area on a weekly basis.  In order to protect the health and safety of the angling public and U.S. Fish and Wildlife Service staff these weekly stockings will now occur on random days of the week.  For more information on our rainbow trout stocking program please contact hatchery personnel at 928-767-3456.

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

  • Check the refuge or hatchery website and call ahead for current information. Operations vary based on local public health conditions.
  • Consistent with CDC recommendations, all visitors (age 2 and older), who are fully vaccinated are required to wear a mask inside of federal buildings in areas of substantial or high community transmission. All visitors who are not fully vaccinated must continue to wear masks indoors and in crowded outdoor spaces.
  • 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.

Current Policies
The Department of the Interior’s current COVID-19 policy incorporates CDC guidance. As CDC science-based guidance changes, our policy will adapt. Visitors have always been encouraged by DOI to review CDC guidance when making their plans to recreate responsibly. CDC guidance indicates that fully vaccinated people are required to wear a mask inside of federal buildings in areas of substantial or high community transmission. Unvaccinated people must wear a mask indoors in DOI buildings at all times and outdoors when physical distancing cannot be maintained. 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. We will continue to ask visitors to follow CDC guidance to recreate responsibly.

We look forward to seeing you soon!

Willow Beach National Fish Hatchery is located on the Arizona side of the Colorado River eleven miles below Hoover Dam, within Lake Mead National Recreation Area. The hatchery works with two endangered species, bonytail chub and razorback sucker, and one candidate species, the relict leopard frog.

Achii Hanyo Native Fish Rearing Facility, a satellite facility for Willow Beach National Fish Hatchery is located on lands of the Colorado River Indian Tribes (CRIT), approximately five miles southwest of the town of Parker, Arizona. The primary focus of this facility is to raise the endangered bonytail chub and razorback sucker.


Willow Beach National Fish Hatchery was established by a Memorandum of Understanding between the Bureau of Reclamation, National Park Service and the U.S. Fish & Wildlife Service on April 24, 1959. Construction began on Willow Beach National Fish Hatchery in 1959 and the first fish were stocked in 1962. The hatchery was established to use the cold water released from Hoover Dam to raise rainbow trout for sport fishing.

Historically, Willow Beach stocked rainbow trout from Lake Powell to Yuma, Arizona. Shortly after the Endangered Species Act was enacted in 1973 the hatchery began working with threatened and endangered fish native to the Colorado River. In the past the hatchery has worked with the endangered Colorado pikeminnow and humpback chub.

In 1996 a Memorandum of Understanding was signed with the CRIT to renovate and dedicate a former commercial aquaculture facility to the rearing and production of the endangered razorback suckers and bonytail chubs, which is now known as the Achii Hanyo Native Fish Rearing Facility. Fish culture operations began in 1998.
