Based on the visual inspection, available records, calculations and past operational performance, Lackawanna Dam is judged to be in good condition. The spillway will pass the Probable Maximum Flood PMF without overtopping the dam. Based on criteria established for these studies by the Department of the Army, Office of the Chief of Engineers OCE, the spillway capacity is rated as adequate. The existing spillway can accommodate a flood with a peak inflow of 117 percent of the PMF peak flow. If the low area of the top of the embankment were brought up to design grade, the spillway could accommodate a flood with a peak inflow of 121 percent of the PMF peak inflow. Author
