National Dam Inspection Program. Ingham Creek (Aquetong Lake) Dam (NDI ID PA 00224, PA DER 9-49) Delaware River Basin, Ingham Creek, Pennsylvania. Phase I Inspection Report,
Abstract
Ingham Creek Dam, which impounds a private recreational lake, consists of an earth embankment approximately 645 feet long with a maximum height of 24 feet. The embankment has a variable top width averaging about 13 feet, a downstream slope averaging about 1.5H:1V and an unknown upstream slope below the water surface. The dam impounds a reservoir with a normal pool surface area of 12.4 acres and a storage capacity of 93 acre-feet. The spillway, located about 95 feet from the left abutment, consists of a rockfill covered with a concrete slab. It is 25 feet long at the crest, 21 feet long at the downstream end, and 25 feet wide. The spillway crest (Elev. 149.8) is one foot below the concrete spillway sidewalls. A wooden sluiceway structure with stoplogs, which is located about 50 feet left of the spillway sidewall, is 5 feet wide by 3 feet deep. It was once used to direct water to a mill downstream of the dam and is now in poor condition. The spillway Design Flood (SDF) chosen for this 'Small' size, 'Significant' hazard dam is the 100 year flood. The spillway is capable of discharging approximately 17 percent of the SDF prior to overtopping the low point of the top of the dam; therefore, it is classified as 'Inadequate'.
