The story so far
Lake Andes, in brief
Wikipedia doesn’t have a history of Lake Andes yet. The photos, dates and memories neighbors add here are how it gets written.
Lake Andes is a city in, and the county seat of, Charles Mix County, South Dakota, United States. The population was 710 at the 2020 census. The town took its name from Lake Andes which some say derives its name from a pioneer hunter named Handy, while others believe was named after Edward Andes, a fur company official. The town and the lake names translate to Bde Ihaƞke in Dakota language of the native Yankton Sioux Tribe.
Its first post office opened in 1900. Between the 2010 and 2020 censuses its population fell from 879 to 710 (-19%).
