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, the condition of Beebe Lake Dam is considered to be good. The examination of documents and visual observations did not reveal conditions which constitute a hazard to human life or property. The spillway capacity was evaluated according to the recommended procedure and it was found that the dam can probably pass the required spillway design floods of 50 percent to 100 percent of the Probable Maximum Flood PMF without significantly affecting the stability of the main dam, if the dam behaves as an arch structure. Therefore, the spillway capacity is rated as adequate. Available documents, including a report by the owner, classifies the dam to be a gravity structure. Assuming behavior as a gravity structure, it was found that the factor of safety against overturning, even under normal pool loading conditions, is marginal. No design and construction information is available to document the precise geometry of the dam and whether it was constructed to function as an arch dam. Therefore, it is considered advisable that the owner undertake further investigations to evaluate the stability of the dam. Author
