Visual inspection of Otisco Lake Dam did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some deficiencies which require further investigation and remedial action. Analysis performed indicated that the structure is only marginally stable under normal conditions and is unstable when subjected to severe loading conditions. The spillway has sufficient capacity to discharge the Probable Maximum Flood PMF, therefore, it has been assessed as Adequate according to the Corps of Engineers screening criteria. The dam has several problem areas which if left uncorrected, have the potential of hazardous conditions. These areas are 1 Repair the deteriorated portions of the concrete on the downstream edges of the concrete paving 2 Repair the undermining of the concrete paving 3 Provide a program of periodic inspection and maintenance of the dam and appurtenances and 4 An emergency action plan must be developed and maintained.
