National Dam Inspection Program. Lake Mokoma Dam (NDS-ID Number PA-359, DER ID Number 57-3) Mill Creek, Sullivan County, Pennsylvania. Phase I Inspection Report.
Abstract
Lake Mokoma Dam consists of an earth embankment constructed over a timber crib. The outlet works is located approximately 100 feet to the left of the emergency spillway and consists of a wet well, valve and pipe. The emergency spillway is located on the right abutment and consists of a concrete lined chute. The spillway is 68.5 feet long with a concrete pier in the middle of the spillway supporting a bridge over the spillway. The spillway exit channel is approximately 100 feet long and consists of a trapezoidal shaped concrete chute. The inspection and review of data of Lake Mokoma Dam did not reveal any problems of any emergency nature. The dam appears to be in fair condition with many deficiencies. The existing spillway and reservoir are capable of passing approximately 15% of the PMF (Probable Maximum Flood). Based upon criteria established by the Corps of Engineers, the spillway is termed seriously inadequate. As a result of the seriously inadequate spillway, the dam is considered an unsafe non-emergency dam.
