The Iowa flood of 2008 was a hydrological event involving most of the rivers in eastern Iowa beginning around June 8, 2008 and ending about July 1.
Flooding continued on the Upper Mississippi River in the southeastern portion of the state for several more days. The flooding included (from north to south, east to west), the Upper Iowa River, the Turkey, and the Maquoketa Rivers; outside of the Driftless Area, they include the catchments of the Wapsipinicon River and that of the Iowa River, to include the latter's major tributary, the Cedar River (and its significant tributaries); and the Skunk River in its various forks.
Amtrak service was rerouted, away from Iowa; a number of trains had their passengers put onto buses.
A study performed by Mark Burton at the University of Tennessee and Michael J.
Hicks at Ball State University was based on post 1993 flood data.
However, the Burton & Hicks study did identify crop damages at roughly billion, which turned out to be very close to the actual damages.
Flooding also forced the closure of an extensive number of roads throughout the eastern half of the state, a situation that affected far more people than those who directly experienced the floods; in particular, portions of Interstate 80 and I-380 were closed.
The closure of bridges in Waterloo, Cedar Rapids and Iowa City disrupted normal traffic patterns, and led to extensive detours. The Iowa, Chicago and Eastern Railroad (IC&E Railroad) had a washout between Mason City and Nora Springs. (CRANDIC/CIC) was particularly affected; its bridge in Cedar Rapids was destroyed by the flooding while an embankment downriver near Coralville was also washed out.
The Keokuk Junction Railway (KJRY) also reported disruptions.However, the 2008 floods damaged key infrastructure outside of the model (e.g.the University of Iowa library) due both to changes in population and flood protection measures.The Des Moines River had some minor flooding, but floodwalls and levees for the most part held fast.The Upper Mississippi River which receives the outflow from all these rivers remained at flood stage.The water flooded parts of the lower campus of Luther College, damaging athletic fields and the Regents Center.
