Visual inspection of this dam and engineering analyses which have been performed revealed that several serious deficiencies exist on this structure. The worst of these deficiencies was the substantial amount of leakage through the dam. There were several areas of concentrated leakage along the interface between the dam and its foundation. Concentrated leakage such as this could adversely affect the stability of the structure. Immediately upon receipt of this notification, a system for providing around-the-clock surveillance of the dam during periods of unusually heavy precipitation should be developed and implemented. Structural stability analyses, based on available information, indicate that factors of safety against sliding are less than desireable for all conditions analyzed. When the dam is subjected to severe loading conditions such as an ice load or a water level at the top of the dam, the factors of safety fall to critical levels. It is recommended that within 3 months of the date of notification of the owner, investigations into the deficiencies on this structure should be commenced. An investigation into the leakage problem is required to determine a means of eliminating or controlling the leakage. Further studies of the structural stability of this structure are also required. Additional hydrologic and hydraulic investigations are required due to the seriously inadequate spillway. Remedial measures deemed necessary as a result of these studies should be completed within 18 months.
