In 1887-88, the Colorado and Southern Railroad built a line and established a station they named Des Moines after Des Moines, Iowa. The St. Louis, Rocky Mountain & Pacific Railway arrived in 1907.
A post office has been in operation since 1906. In 1907, two settlement sites were surveyed. One retained the name Des Moines, and the other Saavedra after its founder. Initially, Saavedra was the more populous of the two places; however, the combined settlement was called Des Moines.
Des Moines initially consisted mostly of hastily constructed shacks. The maximum population of 800 was reached in 1920, but drought and the Great Depression caused a quick decline.
