Episode Narrative Major to near record flooding occurred during the month of April 2008. Flooding continued at some locations from events that began in March, and also continued into May. This particular flood event for most of the region was the worst since 1997. Although the Flood of 2001 saw higher crests on the Mississippi River, that flood affected primarily the Mississippi River itself and only a few of its tributaries. This year's flood event affected the Mississippi River as well as many of its tributaries.

A series of moderate to record high rainfall events continued the flooding at many locations that set flooding in motion at other locations. The most notable heavy rainfall event occurred from April 24-25 when 5 or more inches of rain fell from north central Iowa into southern Wisconsin. The Iowa, Cedar, Wapsipinicon and Maquoketa River basins received the heaviest rainfall. With soil moisture at or above the 95th percentile for that time of year, much of the rainfall became runoff and quickly ran into streams and creeks. The initial result was flash flooding especially across northeast Iowa. The event then transitioned to a river flood event, with major to near record crests experienced on the Cedar, Wapsipinicon and Maquoketa Rivers. The Mississippi River also experienced major flooding. All forecast points on the Mississippi River from Dubuque to Keokuk topped flood stage.

As of April 30th many forecast points continued seeing stages above flood stage. Affected rivers included the Mississippi, Cedar, Iowa, Wapsipinicon and the Maquoketa.
