The historic Swan Falls powerhouse museum is open Saturdays through Sept. 2, from 10 a.m. to 4 p.m. for free self-guided tours. Located along the Snake River about 20 miles south of Kuna, Idaho, Swan Falls Dam became the first hydroelectric project built on the Snake River when it was completed in 1901, and it still generates electricity through a power plant built by Idaho Power in the mid-1990s.
In addition to the museum, visitors can enjoy the adjacent day-use park and picnic area, which includes interpretive signs that outline the geologic and cultural history of the area. Fishing docks, restrooms, boat launches and campsites are also available at Swan Falls.
Pedestrian access across the dam is open during daylight hours.
