National Dam Safety Program. Leatherwood Creek Number 5 (Inventory Number VA 08902), Roanoke River Basin, Henry County, Virginia. Phase I Inspection Report
The purpose of a Phase I inspection is to identify expeditiously those dams which may pose hazards to human life or property. The assessment of the general conditions of the dam is based upon available data and visual inspection. Based upon the field conditions at the time of the field inspection and all available engineering data, the Phase I report addresses the hydraulic, hydrologic, geologic, geotechnic, and structural aspects of the dam. Phase I reports include project information of the dam appurtenances, all existing engineering data, operational procedures, hydraulic/hydrologic data of the watershed, dam stability, visual inspection report and on assessment including required remedial measures. The spillways will pass 30 percent of the Probable Maximum Flood (PMF) or 60 percent of the SDF without overtopping the dam. During the SDF, the dam will be overtopped for a period of 5.5 hours up to a maximum of 1.8 feet and reach a maximum velocity of 5.9 fps. Flows overtopping the dam during the SDF are not considered detrimental to the embankment with respect to erosion. The spillway is judged inadequate, but not seriously inadequate. The visual inspection did not reveal any problems which would require immediate attention. A summary of the design stability analyses for the upstream slope under drawdown conditions and the downstream slope under steady seepage conditions were reviewed and found to be acceptable.
