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 hydrologichydraulic 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 12 PMF respectively. Failure of the dam during the 12 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.
