Storms during June 26-30, 1998, resulted in flooding and widespread damage throughout much of central, east-central, and southeastern Ohio. A total of 23 Ohio counties were declared Federal and State disaster areas, thousands of people were evacuated, more than 100 roads were closed because of flooding, and tens of thousands of people were without power. Twelve people died in Ohio as a result of the storms and flooding; six of the deaths occurred in Noble County alone. Several of the communities that were severely affected by the June 1998 floods had endured severe flooding only 18 months earlier (Jackson and others, 1997).This report describes the meteorologic factors contributing to the floods and provides information on the resulting damages. Peak stream flows, estimated recurrence intervals, and high-water elevation or stage data are reported for selected locations in the State.
