National Dam Safety Program. Swan Lake Dam (Inventory Number NY 333), Delaware River Basin, Sullivan County, New York. Phase I Inspection Report,
Abstract
The Swan Lake Dam was constructed in 1894 and consists of a 112 feel long earth embankment with rockfill core and a 23 feet wide drop spillway located on the eastern side of the embankment. The dam is 31 feet high. There is a bridge over the spillway channel and a mill immediately downstream of the dam. The bridge was abandoned after completion of a new road and bridge located 39 feet upstream of the dam. The mill has also been abandoned and only the foundation and parts of the walls remain. The lake level was raised 4 feet by the installation of stoplogs and concrete support piers which are located at the upstream face of the spillway. The examination of the documents and visual inspection of Swan Lake Dam and appurtenant structures did not reveal conditions which constitute an immediate hazard to life or property. The dam however, has a number of deficiencies which if not remedied may have the potential for developing into hazardous conditions.
