National Dam Safety Program. Clinton Reservoir Dam (Inventory Number NY 212), Mohawk River Basin, Oneida County, New York. Phase I Inspection Report
This inspection did not indicate conditions which would constitute an immediate hazard to human life or property. However, the dam has some deficiencies which require further investigations and remedial work. The structural analysis indicates unsatisfactory stability against overturning for the conditions of the reservoir at spillway crest plus ice loading and the 1/2 PMF and PMF conditions. A stability investigation of the spillway section should be undertaken to determine the factors of safety during extreme loading conditions. A structural stability investigation should be commenced within 3 to 6 months to determine the characteristics of the uplift forces acting on the dam, the properties of the existing dam and foundation, and the effect of these conditions on the stability of the dam. Remedial work should be undertaken depending on the results of this investigation and completed within 18 to 24 months. The hydrologic/hydraulic analysis establishes the spillway capacity as 35 percent of the Probable Maximum Flood (PMF). The dam will be overtopped by 0.7 feet by the PMF and 0.25 feet under the 1/2 PMF. However, a dam break analysis indicates that a dam failure would not significantly increase the downstream hazard to loss of life from that which would occur just prior to the failure. Therefore, the spillway is assessed as inadequate according to the Corps of Engineers' screening criteria.
