Dubois Hatchery Fun Facts

  • The Dubois Hatchery produces around 170,000 fish annually.
  • The Dubois Hatchery incubates up to five million fish eggs annually for use at the hatchery and other hatcheries in Wyoming.
  • The Dubois Hatchery uses a water chiller that allows the hatchery to use water temperature to speed up or slow down the incubation of fish eggs so large groups of eggs collected on different dates can all hatch at the same time.

Where does Dubois Fish Hatchery Get Its Water?


A comprehensive remodel of Dubois Fish Hatchery in 2006 transformed an aging facility into a state-of-the-art high production facility utilizing a partial reuse water recirculation system, maximizing use of a limited water supply. In 2023, due to reduced water flows from the artesian well that provides water to the facility, the hatchery once again started utilizing water from the Jakey's Fork. The creek water is filtered before being disinfected using ultraviolet light.
