National Dam Safety Program. Marcy Reservoir Dam Number 11 (Inventory Number N.Y. 193), Mohawk River Basin, Oneida County, New York. Phase I Inspection Report,

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 Phase I inspection of the Marcy Reservoir Dam No. 11 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. A large area of seepage exists on the southwest slope of the embankment. This seepage extends approximately 250 feet along the embankment, and reaches are elevations of 17 feet below the crest of the dam. A detailed investigation should be commenced within three months to determine the source and quantity of flow in the area of seepage. The hydrologic/hydraulic analysis indicates that the spillway system is capable of passing the 1/2 PMF with 1.25 feet of freeboard. But, the PMF will overtop the concrete box at the downstream end of the spillway and run down along the embankment toe. Therefore, the spillway is assessed as inadequate according to the Corps of Engineers' screening criteria.
