how deep is the missouri river

The Missouri River has an average channel depth typically ranging from 10 to 20 feet. However, the depth varies significantly along its course. In some areas, especially in navigation channels that are dredged, depths can reach up to 150 feet, and in some specially maintained sections, depths can be as much as 200 feet. Reservoirs formed by dams on the river can also reach depths around 175 feet. The riverbed's composition with sand bars, gravel, and boulders causes shallower depths outside the main channel, and the depth fluctuates due to seasonal changes and inflows from tributaries.
