Repairs have started to levee’s along the Missouri River but concerns continue over when the may be finished.

The Corps of Engineers estimate repairs along the river system at more than $600 million from last years flooding.

Winter weather and damage not yet found by the Corps could hinder the timeline of repairs, Corps of Engineers General John McMahon said.

The future also remains uncertain as to flood control.  A study by an independent group says the Missouri Basin rainfall variability is becoming more extreme. There’s a limit to how prepare the Corps can be extremes, McMahon said.  Prepping for extreme events is difficult, he said.
