Floods of August 21-24, 2007, in Northwestern and North-Central Ohio

摘要

This report describes the meteorological and hydrologic conditions leading to the floods, magnitude and frequency estimates for selected rainfall and stream sites, and damage estimates for the affected communities. The USGS located 421 high-water marks along approximately 44.5 miles of streams through the nine communities affected by the floods. The affected communities, main flooding source, extent of the high-water marks, and number of high-water marks within each community are described herein. Peak-streamflow and recurrence-interval estimates were determined for the main flooding source within each of the nine communites. Peak gage-height, streamflow, and recurrence-interval estimates were determined at 22 streamgages in and around the flooded area, 3 of which are located within the 9 communites.
