I know it's a lot to ask, but this graphic published in today's Omaha World Herald might give you a clue:
Somewhere on this flood zone map you will find, in addition to many homes and millions of acres of prime farmland:
- An interstate highway, miles of which may be under 4-6 feet of water
- A nuclear power plant
- One of Cargill's largest facilities in North America (in Blair, NE)
- A major airport ot two
- An airforce base
The good news is that this will not take a lot of lives, it will merely disrupt the Hell out of them.
The bad news is that a lot of real estate in this part of the world may, literally, be under water for the rest of the summer.

Omaha World Herald: Even tamed, river a threat
GAVINS POINT DAM, S.D. — For centuries, the Missouri River flooded. Every year there was a spring and a summer rise. About every other year the flooding spread bluff to bluff.

Human efforts are no match for nature.
“We dammed the river, and we thought it was safe — it became a playground. We had no idea we could get this much,” Yankton resident Judy Christensen said as she watched record amounts of water roar out of the Gavins Point Dam last week.
