National Program of Inspection of Non-Federal Dams Tennessee. Cumberland Springs Lake Dam (Inventory Number TN 12701), Elk River Basin, near Lynchburg, Moore County, Tennessee. Phase I Investigation Report
Cumberland Springs Dam has an 8.3 acre lake and is located near the head of Hurricane Creek in Moore County, Tennessee. The concrete gravity structure has a maximum constructed height of 33 feet and a length of 192 feet, including a 36 foot long ogee spillway. The spillway section also includes a drawdown pipe that is gated on the upstream face. The concrete dam is reinforced with six buttresses on the downstream face. The exposed surfaces of the buttresses are badly weathered with horizontal cracks 6 inches deep on the vertical faces. A horizontal crack was observed on the downstream face of the dam approximately 10 feet above the foundation sill. This crack appears to be in a construction 'cold' joint. Seeps were found in the east end wall and along the foundation sill between buttresses 1 and 2 and 2 and 3. Numerous springs were flowing immediately below the dam and both abutments. Cumberland Springs Dam is in the small size category and has a downstream hazard potential classification of high by the Corps of Engineers and 'I' by the State of Tennessee. On the basis of hydraulic analysis. Cumberland Springs Dam flood storage (15.8 acre-feet) and emergency spillway are inadequate to safely pass the 1/2 Probable Maximum Flood (PMF), which Office of the Chief of Engineers (O.C.E.) Guidelines specify to be the design flood for a dam in the small size and high hazard potential categories. At this time, the dam is considered 'unsafe-nonemergency'.
