National Dam Inspection Program. Koenigs Creek Dam (NDI-PA-00668), (DER-54-169), (SCS-PA-425), Delaware River Basin, Schuylkill County, Pennsylvania. Phase I Inspection Report.
Abstract
The Koenigs Creek Dam is a zoned earthfill dam designed by the U.S.D.A. Soil Conservation Service for flood control purposes. The principal features of the dam include the embankment, a concrete drop inlet type primary spillway and an emergency spillway section at the right abutment. The emergency spillway is constructed as an earth structure with the overflow section about 4.8 feet lower than the crest of the main embankment. A cutoff trench, with a ten foot bottom width and 1H and 1V side slopes, is located on centerline beneath the main embankment. Its depth varies to ten feet. The embankment crest design elevation is 735.6 and its length is 1,180 feet. The height of the dam is 25 feet above the streambed. A seepage drain is located under the downstream slope of the embankment. This drain consists of a 6 inch diameter perforated pipe in a filter bed. The drain discharges to the outlet channel of the principal spillway. The principal spillway is a reinforced concrete riser located at the upstream toe of the embankment near the right abutment of the dam. A pond drain is located 18.5 feet upstream of the spillway structure. A 15-inch cast iron pipe connects the submerged drain intake to the spillway unit. The plans indicate that a 1/4-inch plate is bolted onto a flange at the downstream end of this pipe at its terminus in the inlet structure.
