McNenny State Fish Hatchery produces trout and salmon for stocking across South Dakota. Trout and salmon are not native to South Dakota. High fishing pressure, low natural reproduction, and limited food supplies create the need for stocking.
The hatchery produces approximately 90,000 pounds of fish each year. Three artesian wells and numerous springs provide nearly 4,000,000 gallons of 52-degree water daily. After being used at the hatchery, the water flows into Crow Creek.
Open for visitors Monday-Friday, 10 a.m. to 2 p.m.
No fish are visible for public viewing.
Interpretive signs at the hatchery allow for self-guided tours.
Tours are available only for large groups and must be scheduled well in advance.
