National Dam Safety Program. Main Mill Dam (Inventory Number N.Y. 262), Lake Champlain Basin, Clinton 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. Visual inspection of this dam did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some deficiencies which require further engineering investigations and remedial work. Structural stability analyses performed for this report indicate that the spillway section is unstable for all conditions studied. The analysis was based on the limited information available and so may not reflect existing conditions. However, the analysis does indicate that there is a serious question concerning the stability of this dam and further investigations are required. It is recommended that within 3 months of the date of notification of the owner, investigations into the structural stability deficiencies should be commenced. These studies should include developing accurate cross sections of the dam, progressing subsurface explorations, and coring the dam. This information should then be incorporated into a detailed stability evaluation and the need for modifications to the structure should be determined. Required changes of the structure should be completed within 18 months.
