Big Falls is a large waterfall found on the Missouri River in western Montana, United States. It is also known as Great Falls or Roar of Steam. This waterfall is the biggest and lowest of the group called the Great Falls of the Missouri.
Big Falls is about 87 feet (27 m) tall. It can be up to 900 feet (270 m) wide when a lot of water is flowing. In the past, the falls always had a powerful flow. Today, much of the water is sent away to make electricity. This happens at the Ryan Dam, which is upstream. Because of this, the falls might look like a small trickle during the summer. The dam has made the total height of the water at this spot 177 feet.
