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 documents and the visual inspection of Glenmere 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. Using the Corps of Engineers screening Criteria for the initial review of spillway adequacy, it has been determined that the embankment would be overtopped for all storms in excess of 17 of the Probable Maximum Flood PMF. The spillway is, therefore, adjudged as seriously inadequate and the dam is assessed as unsafe, non-emergency. The classification of unsafe applied to a dam because of a seriously inadequate spillway is not meant to connote the same degree of emergency as would be associated with an unsafe classification applied for a structural deficiency. It does not mean that there appears to be a serious deficiency in spillway capacity and if a severe storm were to occur, overtopping and failure of the dam could take place significantly increasing the hazard to loss of life downstream of the dam.
