The Lake Fish Hatchery Historic District is on the north shore of Yellowstone Lake. The District consists of nine buildings constructed between 1930 and 1932 by the U.S. Fish and Wildlife Service. Most buildings are owned by and under the control of the National Park Service, and are significant for their architecture and for their role in the conservation policies of the Park Service. The design of the buildings follow in whole or part the Rustic Architecture of the National Park Service and its policy of nonobtrusive design which flourished during the 1920s, 1930s, and early 1940s. The buildings are of wood with log framing and cedar shingle roofs. Most are painted a nonintrusive brown with dark green trim.
