Holter Hydroelectric Facility, Dam & Power House, End of Holter Dam Road, Wolf Creek, Lewis and Clark County, MT

Significance: The Holter Hydroelectric Facility is significant for its association with the industrial development of Montana and the consolidation of most of the state's electric industry into The Montana Power Company in the early twentieth century. It also stands as one of the most intact hydroelectric generating plants and operators' camps on the Missoui-Madison Project. The dam and powerhouse structure contributes to the significance of the district as a tangible illustration of Neoclassical industrial architecture typical to the hydroelectric industry in the late 1910s and 1920s. In addition, it represents an important example of the design work of Henry A. Herrick, one of Montana's most noted hydroelectric engineers. The hydraulic and generating equipment in the powerhouse are reflective of hydroelectric plant technologies of the period.
