McNENNY INFORMATION & HISTORY


INFORMATION

Protecting and improving habitat in South Dakota’s lake, stream and marsh systems is a high priority of the South Dakota Department of Game, Fish and Parks. Good habitat is the most important factor leading to good fishing.

The raising and stocking of fish is a secondary tool. It is used with a limited number of sportfish species in situations where natural reproduction of the fish is lacking. This hatchery and other state fisheries stations provide suitable sizes and numbers of fish in these situations.

McNenny State Fish Hatchery is operated by the South Dakota Department of Game, Fish and Parks.  Trout and salmon, not native to South Dakota, are raised here for stocking the state's public fishing waters.

Trout were first introduced into the Black Hills in 1886.  They are now common in many state waters, and do reproduce naturally in some locations.  McNenny supplies trout to waters where natural reproduction does not occur or is too low to provide suitable numbers of fish for anglers.

Chinook salmon were introduced into Lake Oahe, a large Missouri River reservoir, in 1982.  Since natural reproduction of salmon is not possible in Oahe, the population is maintained entirely by stocking hatchery-raised fish.

HISTORY

McNenny Hatchery was originally built and operated by the U.S. Fish and Wildlife Service. The site was formerly owned by James McNenny, who sold it to the State of South Dakota in 1943. The U.S. Fish and Wildlife Service leased the land from the state and constructed the hatchery in 1951.

The hatchery was transferred to the South Dakota Game, Fish and Parks Department on July 1, 1983, and was remodeled to improve the water supply, incubation, and indoor rearing tank system. McNenny Hatchery is one of three state fish hatcheries and is an important part of the Black Hills trout management and Missouri River salmon programs.
