Missouri River flood, Nebraska

In the spring and summer of 2011, the Missouri River experienced extreme flooding. Record snowfall in the Rocky Mountains of Montana and Wyoming, along with near-record spring rainfall in central and eastern Montana, triggered dangerously high reservoir levels in Montana and the Dakotas. A record amount of water was released into the river to prevent overtopping of dams, which contributed to flooding downstream. Warm, dry weather has allowed the river to return to its banks, while cleanup continues on the highways and areas along the entire Missouri River. See also Flooding, Iowa.
