Colter Falls

Colter Falls, also called Coulter Falls, is a waterfall on the Missouri River in north-central Montana, and part of the Great Falls of the Missouri. Downstream of Colter Falls lies Rainbow Falls, and upstream is Black Eagle Falls. The falls is now flooded in the impoundment behind Rainbow Dam. As Rainbow Dam's reservoir is a run-of-the-river reservoir, it rarely is emptied, so the falls are rarely seen even in extreme drought.^[2]: 156
