Book excerpt: The dam is a compacted earthfill structure between earth abutments. The top width is 35 feet for a distance of 150 feet to the right of the spillway while the remainder of the top of dam has been disguised by the dumping of fill material over the downstream face. The total length of the dam is 410 feet between the right abutment and the spillway. The spillway is an earthcut, uncontrolled, open channel and is cut into the left abutment of the dam. No low level outlets or outlet works were provided for this dam. The inspection and evaluation by the consultant's inspection team indicate that the spillway of Smith Lake Dam does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. It was determined that the reservoir/spillway system can accommodate approximately 65 percent of the Probable Maximum Flood without overtopping the dam. The evaluation also indicates that the reservoir/spillway system can accommodate the one-percent chance flood (100-year flood) without overtopping.
