National Dam Inspection Program. Mauch Chunk Lake Dam (PA00605), Delaware River Basin, Mauch Chunk Creek, Carbon County, Pennsylvania. Phase 1 Inspection Report
Mauch Chunk Creek Dam is a 50-foot high rolled earth dam, 1,710 feet long and impounds a 320 acre reservoir. The dam was constructed with local borrow materials and contains one primary material zone with a secondary zone concentrated around the discharge pipes. The primary zone, Zone 2, consists of clayey silty sands and sandy silts classified by the Unified Classification System as SC-SM and SM or ML. Zone 1 materials, classified as low plastic silts (ML), are located around the pond drain and principal spillway discharge pipes, and were placed to minimize seepage along the length of the pipe. The dam contains a rectangular drainage trench located downstream from the centerline. The embankment also contains a cutoff trench under the centerline of the dam. The upstream slope was constructed to 2.9H:IV with an 8-foot wide bench at elevation 1007.7. The crest is 17 feet wide at elevation 1019.8. The upstream slope is protected with riprap between elevations 1014.7 and the bench. The 18-inch thick riprap overlies a 6-inch thick filter bed. The downstream slope was constructed to 1.93H:IV, and is grass/Crownvetch covered.
