The Missouri and Mississippi are both so heavily dammed and engineered, a single dam failure wouldn't propagate very far. It'd be an exciting exercise for the hydrologists, I'm sure. But comparing just the capacity of Fort Peck reservoir versus the total Missouri resevoir system: Fort Peck Lake is the 5th-largest man-made reservoir in the United States. The lake is 134 miles long, has 1520 miles of shoreline, and has a maximum depth of 220 feet. Water is stored at Fort Peck Lake for the production of hydroelectric power. In addition, the water is managed for flood damage reduction, downstream navigation, fish and wildlife, recreation, irrigation, public water supply, and improved water quality. The total storage capacity of the reservoir is approximately 18.7 million acre-feet. The lake drains an area of approximately 10,200 square miles.

The six dams built in Montana, Nebraska, North Dakota and South Dakota transformed one-third of the Missouri River ecosystem into lake environments. web.bryant.edu The flow capacity and engineering of the lower Mississippi is truly phenomenal.
