National Dam Inspection Program. Brussell and Brunner Dam (NDI-PA 00162, PA DER 64-186), Delaware River Basin, Beaverdam Creek, Wayne County, Pennsylvania. Phase I Inspection Report
The Brussell and Brunner Dam, which impounds a 32 acre lake at normal pool elevation, consists of an earth embankment and concrete lined spillway. The dam is privately owned and the reservoir is used for recreational purposes. Based on visual observations made during the date of inspection, the dam is considered to be in fair condition. However, the uneven nature of the surface along the top of the dam is indicative of settlement or poor construction methods. Standing water along the downstream slope at the left abutment, and overgrown weeds and grass cover are other problems concerning the earth embankment that require maintenance and further study. The spillway approach channel constricts the overflow weir and significantly reduces the hydraulic capacity of the spillway. The outlet channel of the spillway shows signs of erosion and requires remedial work and protection. The spillway is now able to pass approximately 55% of the probable maximum flood (PMF), and is therefore considered adequate. A program for installing piezometers should be developed to determine the position of the phreatic surface at selected sections along the embankment, and to detect the source of the wet area. In conjunction with the establishment of piezometers, drilling data should be evaluated to determine if soft or low density zones are prevalent. A line of monuments should be established on the downstream edge of the top of dam to monitor future movement.
