National Dam Inspection Program. Soil Conservation Service. DAM PA-463. NDS I.D. Number PA-00814 DER I.D. Number 45-250. Delaware River Basin, Leavitt Branch: Brodhead Creek. Monroe County, Pennsylvania. Phase I Inspection Report
Soil Conservation Service Dam PA 463 (Leavitt Branch Dam) is a homogeneous embankment composed predominantly of materials classified as sandy silts, Zone 1. The dam is approxmiately 850 feet long, has a crest width of 26 feet, a crest elevation of 1,223.4 and a maximum height at the centerline above the stream bed of 88 feet. The upstream slope is 3.75H:1V with 10-foot and 12-foot wide berms at elevations 1,190 and 1,159 feet, respectively. The slope between the berms is protected with Zone 2 material classified as cobbles and boulders, or other oversize material raked from the Zone 1 fill. The downstream slope is 3.5H:1V, and has two 10 foot wide berms at elevations 1,194 and 1,164 feet. The dam contains an unusual internal drainage system. Drain fill material was placed on the downstream slope of the cutoff trench excavation. In addition, a trench drain was placed about two-thirds of the distance from the centerline to the downstream toe and a blanket drain is under a portion of the dam. Seepage collected in the drains outlets in the impact basin at the downstream toe or through one of the three pipes discharging at the downstream toe.
