Harris Pond Dam is a combination earth, concrete and masonry structure approximately 10 feet high and 135 feet long, including spillway. It is located on Roaring Brook Creek in Ross Township, Luzerne County, Pennsylvania. The overall appearance of the facility suggests it to be in good condition. The only deficiency noted by the inspection team that requires immediate remedial attention was the areas exhibiting concrete deterioration. Flashboards (reportedly removed during significant storms) were observed in-place across the service spillway. Although generally considered undesirable, they appear, in this particular case, to be of little significance relative to the safe operation of Harris Pond Dam.

Bryant Pond Dam is an earthfill and rockfill dam with a concrete core-wall. The earthfill extends along the upstream side of the core-wall and the rockfill extends along the downstream side. The dam, including the main and auxiliary spillways, is 425 feet long. The design height is 19 feet. The main spillway is located near the left abutment of the dam. It is a series of concrete slabs forming a cascade to the natural stream. Other than its exterior lines and grades, details of the main spillway are unknown. The main spillway crest is 40 feet long and 5 feet below the design top of the dam. The auxiliary spillway was designed to be a 175-foot long by 2-foot deep notch in the concrete core-wall. It was constructed 200 feet long. The auxiliary spillway was designed to allow water to flow over the rockfill on the downstream slope of the embankment. The outlet works is located directly to the right of the main spillway. It consists of two 2-foot square concrete conduits with concrete sluice gates at the upstream end. The various features of the dam, as designed, are shown on the Plates at the end of the report. The existing features are shown in Appendix D. (Author).

Lake Jean Dam is a zoned earth embankment approximately 26 feet high and 780 long, including spillway. The emergency spillway is an uncontrolled, rectangular, concrete and rock cut chute channel located at the right abutment. The crest of the spillway is 20 feet long and is spanned by a concrete bridge which supports a portion of the bituminous roadway that covers the embankment crest. Drawdown capability is provided by means of a 30-inch diameter cast iron blowoff pipe controlled at the inlet by a 30-inch diameter sluice gate. The facility consists of a main dam (Lake Jean Dam) and two appurtenant saddle dams (east and west dikes). Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store about 73 percent of the PMF prior to overtopping the east dike. Thus, based on the screening criteria contained in the recommended guidelines, the spillway is considered to be inadequate, but not seriously inadequate. Should the saddle dams be regraded to their design elevation, the spillway would then pass floods in excess of the PMF and would be considered adequate.

Hathaway Pond Dam is located in Ararat Township, Susquehanna County, Pennsylvania. The reservoir was originally created to provide water for power purposes. The reservoir slopes are moderate with a good cover of vegetation. There are three ponds upstream from Hathaway Pond Dam on two tributary streams. The western stream contains Romobe Lake (PennDER I.D. No. 58-10) which is 1750 feet upstream from Hathaway Pond Dam. The eastern tributary contains Ball Lake and an unnamed smaller pond in series. Ball Lake is 2450 feet upstream and will retain considerable storage while the smaller unnamed pond was considered to have no effect on Hathaway Pond Dam. Two homes, a trailer, and township road are located 1800 feet downstream from Hathaway Pond Dam. These could suffer economic damage in the event of a dam failure.
