The Ohio Department of Transportation proposes to relocate an 8-mile segment of State Route 151 between Bowerston and Scio, Harrison County, Ohio. About 3.1 miles of this relocated highway will be within the flood plain of Conotton Creek or its tributaries.
Water-surface profiles of the 100-year flood along Conotton Creek before and after the highway relocation are virtually the same between Bowerston and the western corporation limit of Scio. Upstream from that point to the upper end of the study reach, the modified profile would be about 1 foot lower than for existing conditions. Design-flood profiles on the three studied tributaries showed that Dining Fork profiles will be unaffected, Irish Creek profiles will be 0.7 to 0.9 foot lower, and Scott Run profiles will be 0.1 to 0.5 foot lower.
