National Dam Inspection Program. Sweet Arrow Lake Dam (NDI-PA-00680, DER-54-102), Susquenhanna River Basin, Schuylkill County, Pennsylvania. Phase I Inspection Report.

Abstract

Sweet Arrow Lake Dam is an earthfill embankment with a maximum height of 35.5 feet. The length of the dam crest is about 480 feet. The ends of the embankment tie into the remains of an older and higher dam which failed, due to overtopping, in 1862. A cutoff trench was excavated to solid rock and a grout curtain was installed. The spillway, which has a crest elevation of 14.5 feet below the top of the dam is located in the west (left) abutment, and is separated by a high ridge from the embankment. The 50 feet wide spillway was excavated in rock and is unlined. An intake tower is located at the toe of the upstream slope. The intake is controlled by two 18-inch gate valves and the discharge is through a concrete conduit beyond the downstream toe of the dam.
