National Dam Inspection Program. Lloydell Dam (ID Number PA 500), Ohio River Basin, South Fork Little Conemaugh, Cambria County, Pennsylvania. Phase I Inspection Report
The Lloydell dam is a masonry-gravity structure approximately 700 feet long with a maximum height of 43 feet from the downstream toe. Based on the evaluation of the conditions as they existed on the dates of inspection (May 18 and 30, 1978) and as revealed by visual observations, the condition of Lloydell Dam is assessed to be good. The spillway does not have the recommended capacity to pass the probable maximum flood without overtopping. However, the dam is a masonry structure, and overtopping by the probable maximum flood would not significantly affect the stability of the dam. Therefore, the spillway capacity is considered to be adequate. However, during unusually heavy runoff, when overtopping might occur, an around-the-clock surveillance plan should be implemented to detect possible problems, such as rapid erosion of the abutments. It is recommended that the owner should develop a formal warning system to alert the downstream residents in the event of emergencies. It is also recommended that the owner should take necessary measures to improve the accessibility of the site during high flows.
