National Dam Inspection Program. Morris Run Mine Dam Number 3 (NDI number PA01027, PennDER Number 59-8), Susquehanna River Basin, Morris Run, Tioga County, Pennsylvania. Phase I Inspection Report
Abstract
Morris Run Mine Dam No. 3 is owned by the Borough of Morris Run, Pennsylvania, and is classified as a 'Significant' hazard - 'Small' size dam. The dam was found to be in fair overall condition at the time of inspection. Hydraulic/hydrologic evaluations, performed in accordance with procedures established by the Baltimore District Corps of Engineers, for Phase I Inspection Reports, revealed that the spillway will pass the 100-year flood without overtopping the dam. A spillway design flood (SDF) in the range of the 100-year flood to the 1/2 Probable Maximum Flood (1/2 PMF) is required for Morris Run Mine Dam No. 3. Since the dam is on the low end of the 'Small' size category in terms of storage capacity, the 100-year flood was chosen as the SDF. The spillway capacity is greater than the inflow to the impoundment during the 100- year flood. The spillway is therefore considered 'Adequate'. Several items of remedial work should be immediately initiated by the owner.
