National Dam Inspection Program. Grahamville Reservoir Dam (NDI Number PA-00020) (PennDer Number 25-2) Lake Erie Basin, Sixteen Mile Creek, Erie County, Pennsylvania. Phase I Inspection Report.
Abstract
Grahamville Reservoir Dam is classified as a 'Small' size-'Significant' hazard dam. The structure consists of a zoned, earthfill embankment approximately 29 feet high and 400 feet long. Based on observations made during the visual inspection, data available from the Pennsylvania Department of Environmental Resources' (PennDER) files, and information obtained from interviewing North East Borough personnel and representatives from Hill and Hill Engineers, North East; the dam is considered to be in poor overall condition. Hydraulic/hydrologic evaluations, performed in accordance with procedures established by the Baltimore District of the U.S. Army Corps of Engineers for Phase I Inspection Reports, revealed that the spillway will pass the 100-year flood without overtopping the dam. Therefore, the spillway is considered 'adequate'. It is recommended that the owner initiate a feasibility study to determine if the reservoir is necessary for meeting the water requirements of the borough or whether the effort could be better spent upgrading one of its other reservoirs to meet the requirement for potable water.
