National Dam Inspection Program. Lake Catalpa Dam (NDS-ID Number PA-560), (DER-ID Number 40-57) Susquehanna River Basin, Falls Creek, Luzerne County, Pennsylvania. Phase I Inspection Report
Lake Catalpa Dam is an earthen embankment with dry masonry walls on both the upstream and downstream sides. Portions of the downstream slope have been replaced with concrete walls. The maximum height is 23 feet. The crest width ranges from 27.5 feet to 30 feet, the crest length is 160 feet. A paved road passes over the crest of the dam. Parapet walls are present both upstream and downstream above the roadway elevation. The reservoir drain is operated by a sluice gate located in the valve house and consists of a 30 in. pipe of unknown material. The spillway is a three sided weir structure placed against the upstream wall with a total crest length of 26 feet. The weir crest is formed by an ogee crest with fish screens along the entire length. The ogee slopes to the entrance of a tunnel through the dam. The tunnel is 6 feet wide and 8.1 feet to 12.7 feet high. The tunnel discharges into an open rectangular shaped channel, at the downstream end of the structure. This rectangular channel continues for about 20 feet where it discharges into a tributary of Leonard Creek. The spillway and reservoir are capable of controlling approximately 33% of the PMF. Based on criteria established by the Corps of Engineers, the spillway is termed inadequate.
