Janklow condemns the corps with a flood of allegations, arguing that it failed to anticipate the problems this spring that seemed logical to expect.

"The important thing is how slow-witted does somebody have to be not to have known that we were going to have a heck of a spring?" Janklow said. "Now, we had worse than anticipated ... then it was too late, once the rain came in the spring."

Janklow joined another former governor, Mike Rounds, in that argument. Rounds is personally invested since he is among the evacuees along the Missouri in Fort Pierre. And he wants an inquiry into corps river management and clarification on why more water wasn't moved downstream before above-average snowmelt and gully-washer rains swamped the system.

The corps is expected to do its own review. But Sen. John Thune and Rep. Kristi Noem, both Republicans, had said that after the flood crisis is past, it might be necessary for members of Congress to look at corps water management. Sen. Tim Johnson, a Democrat, has been less critical of the corps, and in fact complimented them last week for their helpful reaction to South Dakota in advance of and during the high flows.

Noem was much less complimentary.
