National Dam Inspection Program. North Lake Dam (NDI I.D. Number PA-00268, PennDER I.D. Number 52-180), Delaware River Basin, Branch of Hornbecks Creek, Pike County, Pennsylvania. Phase I Inspection Report
North Lake Dam is located on a branch of Hornbecks Creek in Delaware Township, Pike County, Pennsylvania. The facility is located approximately 1,500 feet upstream and west of wild Acres Lake, and about five miles from U. S. Route 209 which parallels the Delaware River in this area. Observations made during the visual inspection indicate the embankment is in fair condition, but in need of general maintenance. No evidence of seepage through the downstream embankment face, sloughing, erosion or animal burrows was observed. The embankment crest is noticeably low (in excess of 1-foot) near the spillway relative to the remainder of the crest. About two-thirds of the embankment is overgrown along an area extending approximately 400 feet to the right of the spillway. The vegetation is characterized as primarily brush and high weeds with clumps of small trees strewn throughout. In contrast, much of the embankment crest and upstream face are bare and unprotected with only light vegetation visible. Several long tire ruts scar the crest near the spillway. A small area characterized by swamplike vegetation is located about 350 to 375 feet from the right abutment along the downstream embankment toe. Seepage was observed at the downstream embankment toe near the outlet conduit flowing at a rate of about two to three gpm. The flow is suspected of being either seepage through the embankment foundation, or perhaps drainage from a concealed toe drain. A precise assessment of the condition is difficult without adequate design data are drawings.
