Clark's Fork Fish Hatchery

Clark's Fork Fish Hatchery is the second-largest hatchery in the state. This hatchery focuses on hatching and rearing fish for stocking into waters that allow public fishing. Clark's Fork produces millions of fish each year to bolster populations and support fisheries management in Wyoming.

Hatchery information


The Clark's Fork Fish Hatchery is 29 miles north of Cody, a few miles off Wyoming Highway 120, along the Clark's Fork River in the shadow of the Beartooth Mountains. Yellowstone National Park, Shoshone National Forest and Bureau of Land Management lands are nearby to enjoy. The fish hatchery sits on 195 acres of deeded, Wyoming Game and Fish Department land that includes many public fishing access points.

Clark's Fork Hatchery water


Natural underground springs provide a constant supply of cold, disease-free water to the hatchery. The 12 springs furnishing water to the facility vary from a low of 4,000 gallons per minute in April to a high of 8,000 gallons per minute in October. During peak months, the springs provide approximately 11.5 million gallons of water daily at an average temperature of 52 degrees Fahrenheit. Because the water constantly flows through the hatchery, raceways do not become covered with ice, even on the coldest winter days. After passing through the facility the water returns to the Clark's Fork River.
