Mar 30, 1998
Most of the precipitation in Iowa for the month fell in two storms. The first was mentioned above with the heavy snow event on the 8th. As the snow melted, snow melt and rainfall brought rivers to near or just slightly above flood stage. Heavy rainfall on the 29th and 30th brought up to 4 inches of rain over parts of southeast Iowa, with 1 to 2 inches elsewhere. Areas that were previously dry, mainly in the upper Des Moines and Raccoon Basins, became saturated. Some minor flooding occurred
