National Dam Safety Program. East Canada Lake Dam (Inventory Number NY 201), Mohawk River Basin, Herkimer and Montgomery Counties, New York. Phase I Inspection Report,
Abstract
The examination of documents and visual inspection of the East Canada Lake Dam did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some deficiencies which require remedial work. The hydrologic/hydraulic analysis indicates that the dam will be overtopped by flows in excess of 48 percent of the Probable Maximum Flood (PMF). The dam will be overtopped by 4.9 feet and 0.09 feet by the PMF and 1/2 PMF respectively. Failure of the dam during the 1/2 PMF event would significantly increase the downstream hazard from that which would exist just prior to failure of the dam. The spillway capacity, therefore, is assessed as seriously inadequate and the dam is assessed as unsafe, non-emergency. The structural analysis for the concrete spillway section indicates satisfactory stability for all loading conditions investigated.
