The historic Swan Falls Powerhouse is open for free self-guided tours for two more Saturdays — Aug. 26 and Sept. 2 — before closing for the season.
Swan Falls Dam, 20 miles south of Kuna, Idaho, was built in 1901 to provide electricity to nearby mines. It’s the oldest hydroelectric dam on the Snake River. Idaho Power built a new power plant in the 1990s, which generates up to 27 megawatts of electricity. The old plant was turned into a museum where visitors can see a lot of the equipment dating to the early part of the 20th century.
The museum is open Saturdays through Sept. 2, from 10 a.m. to 4 p.m. Visitors can also check out the exterior of the boarding house once used as a residence for workers at the dam. Interpretive signs in the adjacent park outline the geologic and cultural history of the area.
