Sallet reports that by 1920, there were 4,500 Evangelical and 266 Catholic Volga German immigrants of the first and second generation settled in Montana. They had come there following the development of the Huntley Project, an irrigation project in southern Montana that was established by the United States Bureau of Reclamation in 1907. This irrigation brought water to vast areas of the Yellowstone Valley and spirited development of the sugar beet industry there.
