About

Ryan Dam is a hydroelectric dam on the Missouri River, 10 miles (16 km) downstream from the city of Great Falls in the U.S. state of Montana. The dam is 1,336 feet (407 m) long and 61 feet (19 m) high; its reservoir is 7 miles (11 km) long and has a storage capacity of 5,000 acre-feet (6,200,000 m3). It is a run-of-river dam. The dam is built on the largest of the five Great Falls of the Missouri, the "Big Falls", also sometimes called "Great Falls". Since 1915, the six-unit powerhouse on the left side of the dam has occupied a significant portion of the 87-foot (27 m) high waterfall.
