The Des Moines Metro area saw epic flash flooding on the night of June 30 into the early hours of July 1, 2018 as thunderstorms stalled over the city and dropped significant heavy rain. A widespread swath of 5 to 10 inches fell over the northern half of Polk County and obliterated many creeks. Record stages were set on the Walnut and Fourmile Creeks in Clive and Ankeny, respectively. Dozens of vehicles were stalled or swept away by the rapid currents and multiple homes throughout much of Polk County were impacted by the heavy rain.
