Notes
Survey number HAER MT-97-A
Significance: The Great Falls Hydroelectric Facilities Historic District is significant for its association with the industrial development of Montana and the consolidation of most of Montana's electric industry into the Montana Power Company. The district is also associated with John D. Ryan, the promoter of hydroelectric development at Great Falls. The powerhouse contributes to the significance of the district as a well-preserved example of industrial architecture typical to the hydroelectric industry during the late 1910s to 1920s. The hydroelectric generating equipment installed in the powerhouse is also representative of hydroelectric plant technologies of the period.
