National Dam Inspection Program. Core Creek Dam (PA00802), Delaware River Basin, Core Creek, Bucks County, Pennsylvania. Phase 1 Inspection Report.
Abstract
Core Creek Dam is a zoned rolled earth dam with an interior inclined downstream (chimney) drain. The dam is approximately 860 feet long and 47 feet high as measured from the streambed to the crest. The dam was designed to use locally available borrow materials and contains two primary soil zones. The interior zone (Zone 1) is composed of clays and silty clays derived from local borrow sources. The exterior section (Zone 2) consists of silty sand, also from local sources. The dam contains a cut off trench and a triple line grout curtain. On the downstream side between Zone 1 and 2, the embankment has a two layer chimney drain connecting to a drain trench. The upstream slope is riprapped. Water is normally released from the dam through a principal spillway consisting of reinforced concrete drop inlet structure with water supply gates below the weir crest, a 60-inch diameter prestressed concrete conduit and a reinforced concrete, 82-feet long, SAF type stilling basin.
