National Dam Inspection Program. Beaver Run Dam, NDI Number PA-484. Ohio River Basin, Beaver Run, Westmoreland County, Pennsylvania. Phase I Inspection Report.
Abstract
Based on a visual examination, as well as available engineering data, the dam is considered to be in good condition. Hydrologic and hydraulic calculations indicate that the facility can pass and/or store the flow resulting from the PMF. Additional calculations, however, indicated that if not properly vented, the morning glory spillway may pass through a period when a make and break siphoning action would attend flow. This action would be accompanied by surges at the inlet and outlet ends and by thumping and vibrations within the outlet. Since no design reports are available for the appurtenances, it is not known if this condition was considered during the design. Discussions with owners representatives and local residents also indicated that remedial repair to the outlet works was required at least once and possibly twice since construction. Consequently, it is recommended that a detailed hydraulic and hydrologic analysis be performed to accurately assess the present condition of the outlet and to make any modifications deemed necessary to insure that the outlet will perform adequately under all possible operating conditions.
