National Dam Inspection Program. Pottsgrove Dam (NDI I.D. Number PA-00527, Pennder I.D. Number 7-19) Susquehanna River Basin, Kettle Creek, Blair County, Pennsylvania. Phase I Inspection Report.
Abstract
Pottsgrove Dam is a 37-foot high earth embankment approximately 900 feet long. The embankment is comprised of three sections of which the center section is about 560 feet long. The left and right sections are approximately 90 and 250 feet long (including spillway), respectively, and each form an angle of about 60 degrees with the center section. The facility is served by a concrete and masonry chute channel spillway with an uncontrolled concrete, ogee-shaped weir located within the right embankment section. The spillway has a crest length of 64 feet and is 4.6 feet deep (below wingwall level). In addition, the facility is equipped with a 16-inch diameter cast iron pipe (C.I.P.) blowoff line, and 10- and 12-inch diameter C.I.P. supply lines controlled by gate valves housed within a structure located at the downstream toe of the embankment.
