Barber Dam

Barber Dam is an embankment dam across the Boise River that generates hydroelectric power for the surrounding region. The structure operates continuously to supply electricity using turbine generators housed within its powerhouse.

The Barber Lumber Company built this dam between 1904 and 1906 to support timber processing operations. Over time, its function shifted to serve residential communities with electrical power.

The National Register of Historic Places recognized the dam in 1978 for its role in local industrial development and engineering achievement.

The dam is easily accessible from several viewpoints along the riverbank where you can see the structure up close. The area is suitable for walks at any time of day, making it convenient to visit.

The dam features an unusual timber-crib design that reflects early engineering approaches to dam building. This construction method was common in that era but is rarely seen in modern structures.
