National Dam Inspection Program. Nesquehoning 4th Hollow Reservoir, (NDI-PA-00806), (DER-13-104), Delaware River Basin, Carbon County, Pennsylvania. Phase I Inspection Report.
Abstract
The Nesquehoning 4th Hollow Reservoir Dam originally known as the Broad Run Dam is a homogeneous earthfill dam with a maximum height of 51 feet above the downstream toe. The length of the earthfill is 300 feet. A 50-foot wide spillway is located in the right abutment. This spillway is an ogee type weir having a crest elevation 8.5 feet below the top of the spillway abutment walls. The forebay walls, spillway chute and stilling basin are all formed with concrete walls and slabs. An intake structure is located at the toe of the upstream slope of the embankment and has 4 sluice gates; three for water supply intake and one for drawdown purposes. The conduit through the embankment is horseshoe shaped and has a well defined riprap protected downstream channel. At the exit of the conduit is a small basin with energy dissipators. The water supply intake is through a 16-inch C.I. pipe encased in concrete. (Author)
