The fast-moving Missouri River is making for spectacular displays at the dams that control its flow (see video below).
Hundreds of sightseers are turning out at Oahe Dam near Pierre, Garrison Dam near Bismarck, N.D., and other locations to see the thundering torrents as the Army Corps of Engineers releases water downstream. All the water must be moved along to make room for heavy rains in western states and snowmelt from the Rocky Mountains.
