National Dam Safety Program. Dover Lake Dam (Inventory Number VA 07503), James River Basin, Goochland County, Virginia. Phase I Inspection Report.
Abstract
Dover Lake Dam is a homogeneous earthfill structure about 530 ft long and 36 ft high. The principal spillway consists of twin 48 inch diameter concrete riser pipes and a 48 inch diameter pipe which extends through the structure. The structure is classified small in size and is assigned a significant hazard classification. Based on Corps of Engineers criteria, the appropriate Spillway Design Flood (SDF) is the 1/2 PMF. The spillways will pass 30 percent of the Probable Maximum Flood (PMF) or 60 percent of the SDF without overtopping the dam. The spillway is judged inadequate, but not seriously inadequate. The visual inspection revealed no apparent problems. It is recommended that the owner implement an emergency action plan measure to warn the downstream dwelling of any dangers which may be imminent. Routine maintenance and observation functions which should be initiated within the next twelve months are provided.
