National Dam Inspection Program. Derry Rod and Gun Club Dam (NDI ID number PA-518, DER ID Number 65-143), Ohio River Basin, Miller Run, Westmoreland County, Pennsylvania. Phase I Inspection Report
Abstract
The Dam appears to be in fair condition, with the condition of the operating facilities being considered as poor. The maintenance of the dam and operating facilities is considered poor. The condition of the principal spillway discharge line is in a visibly deteriorating condition at the outlet. A wet area was observed on the downstream slope of the dam. The condition of the wet area did not appear to pose an immediate problem relative to the stability of the structure. Groundwater and surface runoff near the right abutment has caused erosion gullies along the toe of the dam, adjacent to the right abutment contact. The erosion could potentially erode the toe of the dam, and the runoff should be diverted away from the toe of the dam. A low spot was noted during the inspection, and the top of dam should be filled to an elevation consistent with the top of slope at the emergency spillway at the left abutment. The drainline valve has not been operated in several years. The control stem for the valve reportedly is located in the reservoir, but the stem was not visible during the inspection period.
