Floods of June 28-29, 1998 in Ohio

During a 96-hour period extending from June 26 to June 30, 1998, a stalled frontal system produced a series of storms that dumped 10 inches or more of rain on parts of Ohio. The storms occurred at the end of a relatively wet month, resulting in flooding and widespread damage throughout much of central, east-central, and southeastern Ohio. Twenty-three Ohio counties were declared Federal and State disaster areas as a result of the storms and flooding with an estimated economic impact of nearly $178 million. Twelve storm or flood-related fatalities were reported. Flooding was most severe in the Ohio counties of Guernsey, Noble, and Washington, which lie roughly along a north-south line coincident with the band of heaviest rainfall. Some streams in those counties had peak streamflows with estimated recurrence intervals in excess of 100 years.

This report describes the meteorologic factors contributing to the floods and provides information on the resulting damages. Peak-streamflows, estimated recurrence intervals, and high-water elevation or stage data are reported for selected locations in the State.
