Railroad Creek Dam (NDS ID Number 01062, DER ID Number 9-175, SCS Number PA 615), Delaware River Basin, Tributary to West Branch Neshaming Creek, Bucks County, Pennsylvania. Phase I Inspection Report written by Mary F. Beck and published by . This book was released on 1980 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Railroad Creek Dam is a 34-foot-high zoned earth embankment about 1,170 feet long with an emergency spillway at the left end of the embankment. The embankment contains an impervious core constructed over a cutoff trench under the dam centerline. The principal spillway consists of a concrete drop inlet riser, 202 feet of 30 inch diameter reinforced concrete, steel cylinder pressure pipe, with seven anti-seep collars and an impact basin at the downstream toe. The reservoir drain is located at the base of the riser. Because of high pressure gas lines which cross the reservoir area, the pond drain gate is not closed and water is not normally impounded behind the dam. The emergency spillway is a trapezoidal channel excavated around the left end of the embankment. The dam and its appurtenant facilities are considered to be in good condition. Calculations indicate that the existing spillway systems are capable of passing the Probable Maximum Flood (PMF) without overtopping. Therefore, the spillway system is considered to be adequate.

Phase I Inspection Report written by John Henry Frederick (Jr) and published by . This book was released on 1980 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: SCS PA 477 is a 52-foot-high, 1,550-foot-long dam. The embankment contains an impervious core constructed over a cutoff trench under the dam centerline. About 1,270 feet of the embankment is roughly parallel to U.S. Route 22/Interstate 78. The remaining 280 feet of the embankment forms an angle of about 60 degrees with the highway. The shorter leg contains the maximum section and the principal spillway. The principal spillway consists of a concrete drop inlet riser, a 222 foot long, 30 inch reinforced concrete pipe with eight anti-seep collars, and an impact basin. The emergency spillway was excavated through rock at the right abutment. The grass-lined trapezoidal channel is approximately 150 feet wide and 30 feet wide. The dam and its appurtenant facilities are considered to be in good condition. Calculations indicate that the existing spillway systems are capable of passing the Probable Maximum Flood (PMF) without overtopping. Therefore, the spillway system is considered to be adequate.

Phase I Inspection Report written by Mary F. Buck and published by . This book was released on 1980 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Newtown Dam is owned by the Neshaminy Water Resources Authority and maintained by Bucks County. The dam and reservoir are used as a flood control structure for the downstream town of Newtown, Pennsylvania. The impoundment was designed by the United States Department of Agriculture, Soil Conservation Service, in 1976-77 and the structure was officially completed in 1980. The dam and its appurtenant facilities are considered to be in good condition. The dam is classified as an 'Intermediate' size structure with a 'High' hazard classification, consistent with its potential in the event of failure for extensive property damage and loss of life downstream of the dam and in Chalfont, Pennsylvania. In accordance with criteria established by Federal (OCE) Guidelines, the recommended spillway design flood for this 'Intermediate' size dam and 'High' hazard classification is the Probable Maximum Flood (PMF). The Soil Conservation Service designed this dam as a Class C structure, which requires that the spillway systems be designed to pass the PMF. The hydrologic and hydraulic computations presented in Appendix D indicate that the spillway structures are capable of discharging the PMF without overtopping the embankment. Therefore, the structure is considered to have an 'Adequate' spillway system.

Phase I Inspection Report written by Mary F. Beck and published by . This book was released on 1980 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual inspection indicates that the dam and spillway structures of Broomalls Dam are in poor conditon. In 1970, the original spillway capacity was supplemented by the installation of three 27 inch by 43 inch corrugated metal pipe arches, with an entrance invert about five inches above the spillway and discharging at the downstream toe. The November inspection disclosed that surface erosion above the pipes had occurred, probably as a result of surface runoff over the downstream parapet wall. Some erosion below the culvert outlets was evident. Subsequent inspection in February 1980, disclosed considerable erosion and apparent piping at the downstream end of the culverts. One culvert was filled with ice at its outlet and had a column of ice reaching from the outlet to the ground surface. Ice was also visible at the junction of the culverts and embankment. There appears to be a small, constant, undetermined source of water for ice formation. At the requests of local Department of Environmental Resources officials, the Reservoir has been lowered about 2.5 feet through the upper drain. As a result of the rapid deterioration in the condition of the dam since November, the dam is considered to be in an 'Unsafe, nonemergency' condition.

Phase I Inspection Report written by WOODWARD-CLYDE CONSULTANTS PLYMOUTH MEETING PA. and published by . This book was released on 1979 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Warrington Dam is a 45 foot high zoned earth embankment, 1,600 feet long, with an emergency spillway at each end of the embankment. The embankment contains an impervious core constructed over a cutoff trench under the dam centerline. The core and cutoff trench are composed of materials classified as silty clays and clayey silts (Zone 1) and encompassed by less permeable materials classified as silty gravels (Zone 2). The upstream slope is 3H:1V with a 10 foot berm at approximately elevation 241.5, normal pool level. The downstream slope is 2.5H:1V with a 12 foot wide berm that serves as an access road along the downstream face of the embankment. The impervious Zone 1 core upstream slope is 2H:1V and the downstream slope is 1.5H:1V. The 14 foot wide embankment crest is at a design elevation of 272.9. Both upstream and downstream slopes are protected with grass. Embankment seepage is controlled by a drain trench near the downstream toe, which contains a 12-inch perforated drain pipe which discharges through the impact basin at the downstream toe.

Phase I Inspection Report written by WOODWARD-CLYDE CONSULTANTS PLYMOUTH MEETING PA. and published by . This book was released on 1979 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pine Run Dam is a homogeneous embankment with an impervious cutoff trench beneath the centerline of the embankment. The dam is approximately 2,700 feet long and the height, measured from the stream bed to the crest, is 31.8 feet. Embankment fill was obtained from emergency spillway excavation and borrow areas within the reservoir. Zone I materials used in the cutoff trench are classified as low plastic silts, and Zone 2 materials are slightly less plastic but still classified as low plastic silts. The embankment internal drainage system discharges through the sidewalls of Saint Anthony's Falls (SAF) stilling basin at the downstream toe. The upstream slope is 3H:1V and the downstream slope is 2.5H:1V. The crest is 14 feet wide at elevation 287.8. The upstream slope has a 15 foot wide berm at approximately elevation 265, the normal sediment pool level.

Phase I Inspection Report written by Mary F. Beck and published by . This book was released on 1980 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Christman Dam is owned and maintained by Mr. Carl W. Christman. The dam was built for recreational purpose. Visual inspection and review of design documentation indicate that the spillway is in fair condition, but the overall evaluation of Christman Dam is poor. The dam is classified as a small size structure with a high hazard classification, consistent with its potential in the event of failure, for extensive property damage and loss of life in the downstream town of Virginville. In accordance with criteria established by Federal (OCE) Guidelines, the spillway design flood is 0.5 to 1.0 PMF (Probable Maximum Flood). As the height of this dam is near the lower limit for small size dams, and the existing total capacity is about one-third of the upper limit, the selected spillway design flood is 0.5 PMF. Hydrologic and hydraulic computations presented in Appendix D indicate that, under existing conditions, the spillway can pass about 0.59 PMF without overtopping the embankment. Under design conditions, the spillway can pass about 0.88 PMF without overtopping. Therefore, the spillway system of this structure is considered to be adequate.

Pleasant Valley West Property Owners Association. Phase I Inspection Report written by KIMBALL (L ROBERT) AND ASSOCIATES EBENSBURG PA. and published by . This book was released on 1980 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: YMCA Dam is an earthfill dam, 42 feet high and 608 feet long. The crest width is 9 feet. The upstream slope is 2.5H:1V and grass covered. The downstream slope was measured to be 2H:1V and grass covered. The reservoir drain consists of a 24 inch corrugated metal pipe with a concrete endwall located 270 feet from the left abutment. The spillway consists of a 42 foot long ogee section, 150 feet from the left abutment. The inspection and review of data of the YMCA Dam did not reveal any problems which require emergency action. The dam appears to be in fair condition. The seepage which was noted along the toe of dam should be monitored and evaluated by a professional engineer knowledgeable in earth dams. The evaluation should be implemented immediately. The spillway and reservoir are capable of controlling approximately 81% of the PMF. Based on criteria established by the Corps of Engineers, the spillway is termed adequate.

Phase I Inspection Report written by WOODWARD-CLYDE CONSULTANTS PLYMOUTH MEETING PA. and published by . This book was released on 1980 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxford Valley Mall Dam is a homogeneous earth embankment about 1,200 feet long. The height, measured from the top of the embankment to the toe of the impervious fill, is about 27 feet. However, fill extending from the embankment to U.S. Route 1, a distance of about 850 feet, has reduced the apparent height of the embankment to about 13 feet. The eight acre reservoir was formed by excavation to the elevation of the reservoir drain inlet. The spillway consists of an octagonal reinforced concrete intake tower, 851 feet of an eight foot wide by eight foot high conduit and a transition section at the outlet. The dam and reservoir are used to control storm water runoff from the adjacent Oxford Valley Mall. The dam and its appurtenant facilities are considered to be in generally good condition. Calculations indicate that the existing spillway system discharges about 46 percent of the Probable Maximum Flood (PMF) without overtopping. It is assessed that the embankment would probably withstand overtopping for a limited period. Therefore, the spillway system of this structure is considered to be inadequate but not seriously inadequate.

Book excerpt: Suydam Dam is a 24 foot high homogeneous earth embankment, 508 feet long and impounds a 12.1-acre reservoir. The embankment contains a downstream crushed rock trench drain discharging through a 6-inch diameter corrugated metal drain. This pipe discharges at the downstream toe. The upstream slope to elevation 1,285.0 is protected with a 12-inch riprap layer over a 12-inch filter course. The upstream and downstream slopes are 3H:1V and 2H:1V, respectively. Except for riprapped surfaces, both slopes are covered with grass and Crownvetch. The crest is 12 feet wide with a settled design elevation of 1,298.0.

Number 15-301) Delaware River Basin, Beaver Creek, Chester County, Pennsylvania. Phase I Inspection Report written by Mary F. Beck and published by . This book was released on 1980 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is prepared under guidance contained in the Recommended Guidelines for Safety Inspection of Dams for Phase I Investigations. The purpose of a Phase I investigation is to expeditiously identify those dams which may pose hazards to human life or property. The assessment of the general condition of the dam is based upon available data and visual inspections. Detailed investigations, testing and detailed computational evaluations are beyond the scope of a Phase I investigation; however, the investigation is intended to identify the need for more detailed studies. In reviewing this report, it should be realized that the reported condition of the dam is based on observations of field conditions at the time of inspection along with data available to the inspection team. In cases where the reservoir was lowered or drained prior to inspection, such action, while improving the stability and safety of the dam, removes the normal load on the structure and may obscure certain conditions which might otherwise be detectable if inspected under the normal operating environment of the structure.

Phase I Inspection Report written by Mary F. Beck and published by . This book was released on 1980 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep Creek Dam is owned by the Montgomery County Commissioners and maintained by the Parks Department. The dam and reservoir are used for recreational purposes. The dam and its appurtenant facilities are considered to be in fair condition. The dam is classified as a Small size structure with a High hazard classification consistent with its potential in the event of sudden failure for extensive property and loss of life downstream along Perkiomen Creek. In accordance with criteria established by Federal (OCE) Guidelines, the spillway design flood for this 'Small' size dam and 'High' hazard classification is 0.5 to the full Probable Maximum Flood (PMF). As the total storage capacity is nearer the lower limited for the Small size classification, and as the watershed controlled by Deep Creek Dam is small compared to the watershed controlled by downstream knight Dam, the selected spillway design flood is 0.5 PMF. Hydrologic and hydraulic calculations indicate that the spillway structure is capable of discharging about 0.21 PMF without overtopping the embankment at the right abutment. If the right abutment and embankment were raised to the original design elevation, the spillway would be capable of discharging about 0.38 PMF without overtopping. The 0.4 PMF is judged to cause failure of the embankment by overtopping, but failure does not significantly increase the danger to human life or property; thus, the spillway rating for this structure is considered to be Inadequate but not Seriously Inadequate.

Phase I Inspection Report written by Gideon Yachin and published by . This book was released on 1981 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Starlight Lake Dam is located on an unnamed tributary of Shehawken Creek in Buckingham Township, Wayne County, 0.2 mile north west of Starlight, Pennsylvania. The original purpose of the impounded water was for ice harvesting and recreation. Presently, the lake is being used for recreation. The overall appearance of the dam is poor. Locations of observed deficiencies are shown on the General Plan. The profile and typical sections of the dam are presented and are based on field survey made on the days of inspection. The survey datum for this inspection is elevation 1355 feet above mean sea level for the normal water surface of the lake at the top of the spillway flashboard. On the inspection date (12/11/1980), the lake level was approximately at elevation 1355.5 or 0.5 foot above the spillway flashboard. Deficiencies observed during the field inspection are described, visible features are depicted in photographs.

This book was released on 1978 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, available records, calculations and past operational performance, Silver Creek Dam is judged to be in fair condition. The spillway and the low overbanks adjacent to the spillway have sufficient capacity to the Probable Maximum Flood (PMF) without overtopping the dam. Based on criteria established for these studies by the Department of the Army, Office of the Chief of Engineers (OCE), the spillway capacity is rated as adequate. The existing spillway and the adjacent overbanks can accommodate a flood with a peak inflow of 115 percent of the PMF peak flow. (Author).
