This report provides information and analysis on the physical condition of the dam as of the report date. Information and analysis are based on visual inspection of the dam by the performing organization. Examination of available documents and visual inspection of the dam did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some serious deficiencies which require further investigation and remedial work. Hydrologic and hydraulic analysis indicates that maximum spillway discharge capacity is only about 21 of the PMF peak out-flow. The 12 PMF would overtop the concrete and stone masonry dam. Structural stability analysis, indicates that overtopping due to 12 PMF would probably cause failure of the dam. It is judged that failure due to overtopping would significantly increase the hazard to loss of life downstream from that which would exist just prior to failure. Therefore, in accordance with Corps of Engineers screening criteria for review of spillway adequacy, spillway capacity is considered seriously inadequate and the dam is assessed as unsafe, non-emergency.
