National Dam Safety Program. Robert G. Struble Dam (NDI-PA 00621, PA DER 15-298, SCS PA-431), Delaware River Basin, East Branch Brandywine Creek, Chester County, Pennsylvania. Phase I Inspection Report
Struble Dam is a zoned earth embankment, approximately 1,500 feet in length with a maximum height of 31 feet. The dam, a multiple purpose structure, was constructed as a portion of the Brandywine Creek Watershed Project. The reservoir has a normal pool storage capacity of 1,025 acre-feet for sediment accumulation and fish and wildlife. The normal pool surface area is 146 acres. An additional storage capacity of 596 acre-feet is utilized for flood water control. The top of dam elevation is 625.5, the crest width is 14 feet, and the side slopes are 3 horizontal to 1 vertical (3H:1V) upstream and 2.5H:1V downstream. A 12-foot wide berm is provided on the upstream face at Elevation 612.8 and the slope is lined with 18-inch thick riprap from the berm to Elevation 618.8. According to the 'As-Built' plans, the upstream and central portions of the embankment are composed of Zone I material, which is classified as a clayey silt. The central portion includes a cutoff trench with a 12-foot bottom width. The downstream shell (to Elevation 615.8) of Zone II material is classified as silty sand. The two zones are separated by a four-foot wide chimney drain which terminates in a drain trench at the downstream toe of the Zone I material.
