Glenburn Pond Dam is a composite earthfill and dry stone masonry structure, terminating with an earthfill embankment on the left abutment. The 16.3-foot high dam has a total length of 190 feet, including the spillway and the earthfill embankment section. The spillway, located at the middle of the dam, consists of a broad crested concrete weir with an effective length of 51 feet. The upstream approach to the spillway has an earthfill bottom with stone and mortar side walls. There are no other constructed outlets through the dam. Based on available records, past performance, visual inspection, field survey and calculations, the Glenburn Pond Dam is judged to be in poor condition. The present spillway capacity of 464 cfs cubic feet per second can pass approximately 2 of the PMF it is classified as seriously inadequate and the facility is rated unsafe, non-emergency. The bulging dry stone wall and the gradual loss of stone from the supporting buttress wall are of concern. The observed conditions suggest that additional investigations are required to determine the extent of remedial measures necessary to insure the structural integrity of the dam.
