Missouri River Flooding 2011: Responding to a Climate Extreme

Transcript

Doug Kluck, Central Region Climate Services Director, NOAA

This was a very complex situation from a weather, climate, water, and human decision-making point of view. The soils were already wet across most of the Missouri River basin before the heavy snows and rainfall fell this last winter and spring. What made this year a little bit different was that the heavy snow kept accumulating much later in the spring.

Kevin Low, Missouri Basin River Forecast Center Hydrologist

National Weather Service projections during the early spring regarding the plains snowmelt were going well, and then we received something that no one could predict: nearly a year's worth of rain occurred in the latter part of May in eastern Montana, bringing the Missouri headwaters and the Yellowstone into major and record-setting river levels.

People may think that water moving downhill is simple, but when you're dealing with a large watershed, understanding how much-- and where-- river rises will occur is a complex business. May was just the beginning of a summer-long effort to mitigate damages from this historic volume of water as it was routed through the remainder of the Missouri system to the mouth at St. Louis.

People in the Missouri River Basin know that climate extremes can occur.

Although the flood damage from the 2011 event was severe, the coordination by the National Weather Service with her federal, state, and local partners undoubtedly saved lives and protected property.
