The Missouri River, fed by record runoffs from a massive snowpack and heavier-than-normal spring rains in seven states, is in overflow mode and will continue that way through most of August.

The U.S. Army Corps of Engineers is managing the river with releases from six mainstream dams, five of them discharging or ramping up to discharge 150,000 cubic feet per second and the sixth churning through 65,000 cfs.
