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. 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.

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 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.

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 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mill Water Pond Dam is owned by the Bethlehem Mines Corporation. The dam was originally built as an industrial water supply dam for the Grace Mine. As the mine is no longer in operation, water from the reservoir is no longer used. The dam and its appurtenant facilities are considered to be in good condition. The dam is classified as a Small size structure with a High hazard classification, consistent with the dam's location immediately above an occupied dwelling and above commercial buildings and other residences farther downstream on Conestoga Creek. In accordance with criteria established by Federal (OCE) Guidelines, the spillway design flood for this Small size dam and High hazard classification is one-half to the full Probable Maximum Flood (PMF). As the dam height and total capacity are near the lower limit of the size classification, the selected spillway design flood is one-half the PMF. Mining of the deep iron ore body has caused extensive subsidence. The mine waste rock is disposed of downstream of the subsidence area. Therefore, currently, Mill Water Pond intercepts surface runoff only from about 0.31 square mile immediately above the dam. Hydrologic and hydraulic computations presented in Appendix D indicate the maximum spillway capacity is greater than the peak PMF inflow from the reduced watershed. Therefore, the spillway system of this structure is considered to be Adequate.

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 and published by . This book was released on 1980 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: This flood control dam consists of a 1000-foot-long earthfill embankment with a maximum height of 25 feet. Seven hundred fifty feet of the embankment crosses the valley, the other 250 feet ties the embankment to higher ground in the left abutment. The principal spillway is a drop inlet structure with an orifice opening and discharges through a 30-inch diameter pipe. This spillway is designed to handle a 100 year flood. For any larger floods the emergency spillway is required. This grassed earth spillway is located in the right abutment and has its design crest elevation 4.6 feet below the top of embankment. The emergency spillway has a channel bottom width of about 60 feet. Based on the visual inspection, past performance and the available engineering data, the dam and its appurtenant structures appear to be in good condition. The spillway capacity is adequate to pass the PMF peak inflow without overtopping the dam.
