About Big Falls
Big Falls — historically called Great Falls or the Roar of Steam — is the lowermost and largest of the Great Falls of the Missouri. The curtain of water plunges about 87 feet (27 m) and can spread as wide as 900 feet (270 m) at peak flow, a striking reminder of the Missouri River’s power. Today most of the river’s flow is diverted to the 60-megawatt hydroelectric plant at nearby Ryan Dam, so what once roared year-round can be reduced to a trickle during summer months, giving visitors a vivid view of how hydropower has reshaped the river. Big Falls makes for an easy, rewarding stop for day hikers, families, and photographers drawn to Montana’s river landscapes and industrial history. Short access and clear viewpoints let you quickly reach dramatic overlooks of the falls and the Missouri River; bring a camera and expect changing water levels that tell the story of natural drama and engineered change.
