The D.C. Booth Historic National Fish Hatchery and Archives, also known as the Spearfish Fisheries Center or Spearfish Fisheries Complex and formerly known as the Spearfish National Fish Hatchery, is one of 70 fish hatcheries that were opened by the U.S. Fish and Wildlife Service as part of the National Fish Hatchery System. The hatchery was established near Spearfish, South Dakota in 1896, with the purpose of introducing and establishing populations of trout in the Black Hills of South Dakota and Wyoming. It is one of the oldest fish hatcheries in the United States[1] and is the second-oldest in the American West.[2] The hatchery spawns and releases about 20,000 to 30,000 rainbow trout each year.[2] The hatchery doubles as a fisheries archive with the purpose of preserving records and early historical artifacts.[3] It is listed on the National Register of Historic Places.[4][5]
