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. Based on the evaluation of the existing conditions, Dansville Reservoir Dam is considered to be in fair condition. The examination of documents and visual observations did not reveal conditions which are considered to constitute a hazard to human life and property. The upstream face and portions of the downstream slope of the dam are covered with large trees, requiring clearing under the supervision of a professional engineer. The spillway apron slab was found to be undermined and the concrete is deteriorated, requiring repairs. The spillway capacity was evaluated according to the recommended procedure and was found to pass 70 percent of the Probable Maximum Flood PMF without overtopping the dam. Because the spillway capacity is less than the recommended spillway design flood of full PMF, the spillway capacity is rated to be inadequate. Author
