National Dam Inspection Program. Star Junction Number 2 Dam. (NDI Number PA-00212 PennDER Number 26-31) Ohio River Basin. Fayette County, Commonwealth of Pennsylvania. Phase I Inspection Report,

Abstract

Star Junction No. 2 Dam consists of an earthfill embankment and masonry spillway on the left abutment. The dam has a crest length of 341 feet, a maximum height of 30 feet and a storage volume of 31 acre-feet at the spillway crest level. The dam is classified by Corps of Engineers guidelines to be a small size, high hazard structure. Star Junction No. 2 Dam's embankment is assessed to be in poor condition. This is based on visual observations of the non-uniform slope, wet zones and state inspection reports. The downstream control was observed to be damaged and probably is not operable. No control or mechanism was observed to permit upstream flow control. The principal spillway is assessed to be in very poor condition. This is based on visual observations of the weir wall and training dike retaining wall. Both structures are partially collapsed and badly deteriorated and safe performance is questionable in the event of long-term, high discharge conditions.
