Thompson Falls Dam, Hydroelectric dam in Sanders County, Montana.
Thompson Falls Dam is a hydroelectric facility on the Clark Fork River made up of four separate structures that work together to harness the river's flow for power. The complex spans a considerable length along the river and creates multiple water levels across the landscape.
Construction began in 1915 under the Montana Power Company and marked a turning point for industrial development in the region. The completion of the facility demonstrated how local rivers could be engineered to power growing communities.
The Thompson Falls Hydroelectric Dam Historic District represents the early industrial development of Montana through its preserved engineering structures and techniques.
Visitors can walk along trails on an island between the structures to view all four dams and take photographs from multiple vantage points. The walking paths offer the best views and are accessible during daylight hours year-round.
The island separating the dams sits where the natural waterfall once flowed before the structures were built. Few visitors realize they are standing on what was once part of the river's most dramatic feature.
