Old Canyon Ferry Dam and power plant

No reviews yetUSA, Montana

The old Canyon Ferry Dam was built in 1896 and formed a reservoir known as Lake Sewell. The old 7,500-kilowatt power plant was completed in 1898. It was dismantled prior to the completion of the new Canyon Ferry Dam and power plant with the remnants having been inundated and Lake Sewell becoming part of the new reservoir. This is a difficult, deep dive, and should not be attempted without local, knowledgeable guidance. The dam and power plant are located about 1-1/2 miles upstream from the existing Canyon Ferry Dam.
