First described by Pierre-Jean De Smet, a Jesuit priest, in a letter dated August 24, 1851, it was a highly saline lake capable of housing only limited aquatic life in its early years. Throughout its history, it changed hands multiple times, with its owners including Levi Leiter, Reynolds Mining, and Texaco. In 1865, the Powder River Expedition passed by the lake during its military operations against various Native American people, including the Lakota Sioux, the Cheyenne, and the Arapaho. The Lake Desmet Segment of the Bozeman Trail is located around a mile west to the lake.
