Overview

Widespread rainfall between 1 and 2 inches fell over frozen and saturated ground during the 19th and 20th of February.  Much of the rain became runoff and went into area streams and rivers.  Melting snow from the 2nd week of February and ice jams, also contributed to the rises.  The Rock and Pecatonica rivers in IL were hardest hit, with both reaching major flood stage.
