Late Sunday afternoon around 6 pm, the stage on the Little Sioux River at Cherokee, Iowa reached a record 27.30 feet. This eclipsed the former record of 27.20 feet which occurred on April 7, 1965. In comparison, the former record was a snowmelt flood, while the current levels are a result of heavy convective rainfall from Saturday evening and overnight which brought a widespread 4 to 8 inches rainfall to most of Cherokee county. The former record high stage which resulted from heavy convective rainfall was from July 18, 1993, when the river reached a stage of 27.08 feet.
