Swan Falls Dam and Park

Oldest hydroelectric generating dam on the Snake River!

Swan Falls is located along the Snake River about 20 miles south of Kuna, Idaho and is another great daytrip in the Treasure Valley. There are outstanding canyon views and good smallmouth bass fishing along the riverbank. Bird watching is also amazing in this area within the Morley Nelson Snake River Birds of Prey National Conservation Area (NCA). You may see owls, osprey, eagles, hawks and falcons!

Swan Falls is also part of the Western Heritage Historic Byway, which includes Celebration Park, Swan Falls Dam, Snake River Canyon Overlook, Dedication Point, Initial Point, Silver Trail, Birds of Prey National Conservation Area, Pioneer Cemetary, and Historic Kuna.


Swan Falls Dam is about 40 miles south of Boise on the Snake River. The dam was built in 1901 to provide electricity to mines in the Owyhee Mountains and is the oldest hydroelectric generating dam on the Snake River. The old plant became a museum when Idaho Power built a new power plant in the mid-1990s.

The Owyhee Avalanche newspaper reported news to Silver City and surrounding areas about the construction of the Swam Falls Dam, and on April 5, 1901, informed residents when electricity was first being brought to the area:

"Poor old useless, treacherous Snake River which has glided for ages between its frowning walls of lava. . . Man’s ingenuity! A dam is thrown across a useless stream, dynamoes are revolved by the weight of imprisoned water, a line of poles and wires is run over the hills and through the canyons thirty miles to the mines, touch a button and the river does the rest. Such is the story. Wonderful, isn’t it?"

On April 10, 1901, the Owyhee Avalanche reported that:

"Trade Dollar superintendent Joseph H. Hutchinson dedicated the big electric motor at the Blaine mill. He shouted, "Electricity! May she be a success! Here’s luck, boys!” About that time, thirty miles away, Miss Nellie Hutchinson set the generating plant in motion. Mrs. Joseph Hutchinson threw the mill motor switch, and within three minutes the mill was in full operation."

The museum is open to the public, from 10AM to 4PM on Saturdays between April 15 and Labor Day. Tours outside those times may be arranged by contacting Idaho Power at least one week in advance.

Also, check out the interpretive signs in the adjacent park that outline the geologic and cultural history of the area.

Pedestrian access across the dam is open during daylight hours.
