The first river flooding in the Des Moines Hydrologic Service Area since July of 1999 developed as a result of heavy rains across northern and northeast Iowa on May 30 through 31. Beaver Creek at New Hartford was the only forecast point to reach flood stage as a result of these rains and crested about 1.3 feet above flood stage early on the 2nd. Several other forecast locations crested just below flood stage during this initial flood event.
