Organization of Indian Lake Township was approved by the Nobles County Board on April 22, 1871. The township was named for the lake within its borders. The lake was named Indian Lake due to the fact that settlers found Native Americans encamped along the lake's shores when they first arrived in 1869. A dozen years earlier, a band of Indians led by Inkpaduta, the group responsible for the 1857 Spirit Lake Massacre, lived along the shores of the lake. Indeed, the women and children of Inkpaduta's band were camped at Indian Lake when the massacre was taking place. Inkpaduta later fled westward, joining up with the Lakotas. He became a close friend of Sitting Bull, and participated in the Battle of the Little Bighorn and the defeat of George Armstrong Custer. It is believed that Inkpaduta died in Canada in 1881 or 1882. Issac Horton, a pioneer settler, was the first to take up permanent residence along the shores of Indian Lake. He had been renting a farm near Spirit Lake, Iowa and frequently came to the Indian Lake region to hunt elk. On May 6, 1869, he filed a preemption claim to the eastern half of section 34 of Indian Lake Township. His claim included the eastern shore of Indian Lake. He erected a cabin of logs cut from his claim, and resided there for 17 years. Horton eventually sold his claim and purchased the southwest quarter of Indian Lake Township section 22 where he resided until his death in 1892. Other early settlers in Indian Lake Township included Ole Fauskee and his family. Ole migrated from Norway to the United States in 1867 when he was 25 years old. He was travelling through southwest Minnesota with his brother when his ox team gave out. He liked the country he saw, and on June 8, 1870, he and his brother walked all the way to Jackson, Minnesota, to file claims. Ole Fauskee claimed the northwest quarter of section 6 of Indian Lake Township, and his brother made an adjacent claim. Fauskee erected a sod hut on the banks of East Lake Ocheda and lived there for five years. He also claimed the northeast quarter of section 12 of Bigelow Township. Fauskee eventually built a home of lumber there, and prospered as a farmer.
