Abstract:

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. The examination of the available documents and the visual inspection of the Findley Lake Dam did not reveal conditions which constitute an immediate hazard to human life or property. However, this dam has deficiencies which require further investigation and remedial action. Using the Corps of Engineers screening criteria for review of spillway adequacy, it has been determined that the dam would be overtopped for all storms exceeding approximately 20 percent of the PMF. The overtopping of the dam could cause the erosion of the embankment, especially around the outlet conduit, which would result in dam failure, thus significantly increasing the hazard to the loss of life, especially on the New York State highway which traverses its crest. To a lesser degree, there is also a potential loss of life by overtopping or breaching a downstream village street which is the only other connection between 2 halves of the Village. The spillway is, therefore, adjudged as seriously inadequate and the dam is assessed as unsafe, non-emergency.
