Ryan Dam is a hydroelectric dam on the Missouri River, downstream from the city of Great Falls, Montana, Great Falls in the U.S. state of Montana. The dam is long and high; its reservoir is long and has a storage capacity of . It is a Run-of-the-river hydroelectricity, run-of-river dam. The dam is built on the largest of the five Great Falls (Missouri River), Great Falls of the Missouri, the "Big Falls (Missouri River waterfall), 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 high waterfall. The dam, built in 1915 just upstream of the falls and a small island named Ryan Island, is divided into two parts. On the right side of the dam is a concrete-arch spillway structure, that when functioning, releases water over the remains of the waterfall.

Big Falls (Missouri River Waterfall)
Big Falls (also called Great Falls or Roar of Steam) is a major waterfall located on the Missouri River in western Montana in the United States. It is the lowermost and largest of the Great Falls of the Missouri, at high and up to wide at peak flow. Although the falls used to flow powerfully year-round, most of the water is now diverted to the 60 megawatt hydroelectricity, hydroelectric plant of upstream Ryan Dam, reducing it to a trickle in the summer months. The dam raised the total height of the water to 177 feet. The Mandan Indians knew of the group of the falls and called them by a descriptive (but not formal) name: ''Minni-Soze-Tanka-Kun-Ya'',McEneaney, Terry. ''The Birder's Guide to Montana.''
