STOKE-111 Final Report
DAM HYDRAULIC CAPACITY ASSESSMENT REPORT (DRAFT) TOWN FORK CREEK WS DAM #7 STOKE-111 STOKES COUNTY, NC PREPARED BY: HDR Engineering Inc. of the Carolinas under contract with WOOD E&I Solutions 2020 EXECUTIVE SUMMARY A hydraulic capacity analysis was completed for the Town Fork Creek WS Dam #7 in Stokes County, North Carolina. The purpose of the study was to analyze the existing potential of the dam for overtopping during predetermined specified rainfall events using the North Carolina Dam Safety defined process and templates. The analyses were completed using the United States Army Corps of Engineers developed software Hydrologic Engineering Center – Hydrologic Modeling System (HEC-HMS) in combination with Arc-GIS to develop required input parameters. The rainfall events included in the analyses consist of 24-hour durations with return periods of 25 years, 50 years, 100 years, 200 years, 500 years and 1000 years. Results of the analyses indicate that this structure is hydraulically adequate for 25 years, 50 years, 100 years, 200 years, 500 years, and 1000 years rainfall events. Data, input parameters, and final results can be found on the attached summary sheets and in the appendices of this report as well as in the associated electronic file in which all program files are stored.
