In the Early 1900s the southern area of Idaho went was part of a massive reclamation project and many irrigation projects were completed. This made the region livable for growing crops and ranching. In 1905 the Milner Damn was completed, along with a canal network supplying water to 200,000 acres of land, on the south side of Snake River Canyon. This attracted large numbers of settlers to the region.
The community was initially settled around 1910 by Dutch immigrants from Iowa. The town's post office was established in 1912.
