摘要

Glades Dam is a homogeneous earthfill dam with a maximum height of 24 feet and a crest length of 960 feet. The dam, owned and operated by the Pennsylvania Game Commission, is used primarily for waterfowl protection. The spillway, consisting of a concrete ogee overflow with a slotted flip bucket energy dissipator, is located at the left abutment of the dam. The crest length is 100 feet. The discharge channel is lined with riprap for 130 feet downstream from the flip bucket. The intake tower and 54 inch outlet conduit are located 400 feet from the left abutment of the dam. Two 3 foot by 5 foot sluice gates (El. 1197.0 feet and El. 1190.0 feet) are used to control the pool elevation. The 54 inch reinforced concrete pressure pipe outlet conduit has four cut-off collars on 26 foot centers along the upstream portion. A discharge basin is located at the downstream end of the outlet conduit.
