The Lake Fish Hatchery Historic District had a prominent role in Yellowstone National Park's fishery management program. The historic district is on the north shore of Yellowstone Lake, the largest mountain, high altitude lake in the United States at 7,733 feet above sea level. The lake is approximately 20 miles long and 14 miles wide. The lake harbors six fish species: cutthroat trout, longnose dace, redside shiners, lake chub, long nose suckers, and lake trout. The former two are native; the latter four were introduced in the mid-1900s.

The Lake Fish Hatchery Historic District consists of nine buildings, constructed for the Fish and Wildlife Service. The fish hatchery activities function was halted in the 1958. Shortly thereafter (during the Mission 66 project [a 10 year effort to upgrade facilities in the parks]), the Lake Hatchery site was adapted to use as headquarters for the southern Lake Maintenance district for Yellowstone National Park. - AsNotedIn
