Flood in Chickasaw County, Iowa

Significant runoff from heavy rainfall upstream resulted in a rapid rise of water and minor flooding along the Little Cedar River near Nashua on May 16th. Minor flooding was initially realized during the early morning of May 16th, with the river cresting 0.94 feet above flood stage of 954.5 feet above sea level on the afternoon of May 16th. It then fell below flood stage late that night.

Four consecutive days of light to heavy rainfall events during the middle of May resulted in near 1.5 inches and some minor flooding along the more narrow, shallow rivers in northeast Iowa. Initial light to moderate rainfall on May 12th quenched soils from a drier than normal spring, while subsequent storms over the weekend of May 13th-14th resulted in rapid runoff and minor flooding along the Little Cedar and Turkey Rivers. Along the Little Cedar River, the highest realized height above flood stage occurred in Nashua (Chickasaw County) on May 16th with 0.94 feet. Along the Turkey River, the river gauge in Cresco (Howard County) crested 0.57 feet above flood stage on May 15th.
