Swan Falls Dam is on the Snake River about 40 miles south of Boise. It was built in 1901 to provide electricity to nearby mines in the Owyhee Mountains. Swan Falls is the oldest hydroelectric generating site on the Snake River. Idaho Power built a new power plant in the mid-1990s. The old plant is now a museum. The museum is open to the public, from 10 a.m. to 4 p.m. every Saturday between April 15 and Labor Day. Tours at other times may be arranged in advance by contacting Idaho Power by email…
