National Dam Safety Program. Churchtown Dam (Inventory Number NY. 79), Lower Hudson River Basin, Columbia County, New York. Phase I Inspection Report,
Abstract
Visual inspection of this dam and engineering analyses which have been performed revealed that several serious deficiencies exist with this structure. Structural stability analyses, based on available information, indicate that this dam is marginally stable under normal loading conditions and is unstable when subjected to severe loading conditions (such as flood flows or ice loading). Seepage noted under and through the structure, creating wet, soft areas along the downstream toe along both ends of the dam, 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. An emergency action plan for the notification of downstream residents should also be developed. It is recommended that within 3 months of the data of notification of the owner, investigations into the deficiencies on this structure should be commenced. Studies of the structural stability and seepage problems, including subsurface and structural explorations are necessary. Information obtained should be incorporated into a detailed stability evaluation.
