National Dam Inspection Program. Oneida Mining Co. Dam (NDI PA-830), Ohio River Basin, Unnamed Tributary to Brush Creek, Indiana County, Pennsylvania. Phase I Inspection Report
The Oneida Mining Company Dam is a zoned earthfill embankment approximately 900 feet in length with a maximum height of 50 feet. The structure is provided with a tapered clay core founded on alluvial materials in a 10-foot deep cut-off trench. The facility is served by an emergency spillway, principal spillway, and a pumping system. The emergency spillway is cut into natural materials on the right abutment and lined with riprap to a height of five feet above the spillway floor. The principal spillway is composed of a 30-inch diameter steel riser set on the upstream left abutment at normal pool elevation 1735. A 24-inch diameter blow-off pipe provides for emergency drawdown. The blow-off pipe is valved at the bottom of a manhole accessible from the embankment crest. By-pass piping is also provided on the blow-off line in order to maintain minimum required downstream flow. The water supply system consists of two 12-inch diameter steel pipes with intake elevations at 1720 and 1725, respectively. This system supplies water for use in the preparation plant and related facilities.
