Lake Andes, SD, is a natural prairie pothole formed by a glacier, located on the Yankton Sioux Reservation. Historically, it was an important camping and tanning site for the Yankton Sioux, who used its resources for centuries before it became a popular tourist destination in the early 1900s. Due to a history of cyclical drought, the Bureau of Indian Affairs (BIA) commissioned artesian wells starting in 1896 to keep the lake full. The lakebed is now protected for wildlife conservation as the Lake Andes National Wildlife Refuge, established in 1936. [google ai summary, accessed October 2025].
