National Dam Inspection Program. Ilion Reservoir Number 1 Dam (NY 00186), Mohawk River Basin, Town of German Flatts Herkimer County, New York. Phase I Inspection Report
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. Examination of available documents and visual inspection of the dam did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some deficiencies which require further investigation and remedial work. The downstream slope of the dam is about 1.5H:1V, which is considerably steeper than that of similar dams designed in accordance with modern standards of practice. Therefore, it is recommended that a stability investigation of the embankment, with particular attention to the steepness of the downstream slope, be started within 6 months after receipt of this report by the Owner. Any necessary remedial work should be completed within 18 months after receipt of this report by the Owner. The investigation and the design and construction observation of any remedial work should be done by a qualified, registered professional engineer. Hydrologic and hydraulic analysis indicates that the PMF overtops the embankment. The 1/2 PMF, however, does not overtop the embankment. Therefore, in accordance with Corps of Engineers' screening criteria for review of spillway adequacy, spillway capacity is considered 'inadequate', but not seriously inadequate.
