Abstract
Edinboro Lake Dam is an earthfill dam with a concrete gravity spillway, approximately 200 feet long and 17.5 feet high. A concrete bridge spans the spillway crest. An 7.7 foot wide by 9.5 foot high concrete conduit exists through the earthen embankment with the entrance to the conduit located approximately 40 feet left of the left abutment of the spillway gravity section. The outlet of the conduit consists of a 36 in. corrugated metal pipe located approximately 70 feet from downstream toe of the left embankment section. The spillway is a concrete gravity structure having a length between abutments of 83 feet. There are 6 piers, each 12 in wide projecting above the crest. Between the 6 piers there exists iron supports which allow the insertion of flashboards. The spillway and reservoir are capable of controlling approximately 39% oft he PMF. Based on criteria established by the Corps of Engineers, the spillway is termed seriously inadequate due to downstream conditions associated with a failure of the gravity spillway section. Edinboro Lake Dam is Classified as an unsafe nonemergency dam.
