Book excerpt: Saul Run Dam, a flood water retarding dam designed by the U.S. Department of Agriculture, Soil Conservation Service (SCS), is also known by its SCS number PA-458. The homogeneous earth embankment has a crest length of approximately 1700 feet and a miximum hength///eight of about 40 feet. The dam crest at El. 1113.6 feet has a width of 16 feet. The upstream slope has an inclination of 3H:1V (horizontal:vertical) and an 8-foot wide berm at El. 1085 feet. The downstream slope with an inclination of 2.5H:1V also has an 8-foot wide berm at El. 1084 feet. A foundation cutoff trench with a base width of 12 feet, 1H:1V side slopes, a length of about 100 feet, and a depth of about 5 feet to bedrock was constructed in the valley bottom (Plate 5). Cutoff trenches of similiar cross-section were also constructed in the soil abutments (Plate 5). The outlet works (principal spillway in SCS terminology) consist of a reinforced concrete riser connected to a 24-inch diameter reinforced concrete pipe is located beneath the embankment in the valley bottom. The outlet pipe, with six reinforced concrete anti-seep collars, was installed on a concrete cradle founded on bedrock.
