National Dam Safety Program. Lake Placid Village Dam. (Inventory Number NY 781), Lake Champlain River Basin, Essex County, New York. Phase I Inspection Report
The examination of documents and visual inspection of the dam and appurtenant structures did not reveal conditions which constitute an immediate hazard to human life or property. The dam, however, has a number of problem areas which require further investigation and remedial work. The structural stability analysis indicates that the dam is unstable when subjected to forces which could occur under the Probable Maximum Flood (PMF) loading condition. Unsatisfactory stability is indicated for the dam when subject to forces which could occur during the normal winter operations and the 1/2 PMF loading condition. A structural stability investigation should be started within six months to determine the characteristics of the uplift forces acting on the dam and to determine whether the foundation acts integrally with the dam section to resist overturning. Remedial work should be completed, depending on the results of the investigation, within two years. The hydrologic/hydraulic analysis establishes the spillway capacity as 10.7% of the Probable Maximum Flood (PMF). The dam will be overtopped by 10.0 feet and 4.8 feet during the PMF and 1/2 PMF respectively. The spillway is inadequate since failure of the dam during the 1/2 PMF event will not significantly increase the downstream hazard from that which would occur just prior to the dam failure.
