Phase I Inspection Report written by O'BRIEN AND GERE ENGINEERS INC PHILADELPHIA PA JUSTIN AND COURTNEY DIV. and published by . This book was released on 1979 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scott's Run Dam is a zoned earth embankment, approximately 625 feet in length with a maximum height of 34 feet. The dam was constructed for recreational purposes and impounds a reservoir with a surface area of 21.9 acres and a storage capacity of 200 acre-feet at normal pool. The top of the dam is 14 feet wide and the side slopes are 3H:1V upstream and 2H:1V downstream. A cofferdam is incorporated into the upstream face of the embankment, forming a 28-foot wide berm from Elevation 582.0 to 584.0. The upstream slope is 2.5H:1V below the berm elevation. According to the information obtained from DER, the embankment is constructed in 3 zones. A central core section with 0.6H:1V side slopes is composed of selected impervious material (class 'A' material). A cutoff trench with 1H:1V side slopes and a 16-foot bottom width is excavated into impervious foundation material below the central core and is also composed of Class 'A' material. The upstream shell of the embankment consists of less impervious material (class 'B' material) and the downstream shell is composed of pervious material consisting of sand and some stones (class 'C' material). According to available information, a concrete cutoff wall extends through the cutoff trench and into the foundation material below the cutoff along the axis of the dam. Seepage control is provided by a downstream toe drain composed of gravel and small stone and an upstream impervious blanket (class 'A' material) which extends approximately 500 feet beyond the upstream toe.

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 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sand Spring Run Dam is a recreational structure located in Hickory Run State Park and owned by the Commonwealth of Pennsylvania. The visual inspection and review of design and construction documentation indicate that the embankment and outlet structure are in good condition, the concrete weir is in fair condition, and the vegetation is in poor condition. The overall assessment is considered to be fairly good at the present time. In accordance with criteria established by Federal (OCE) Guidelines, the recommended spillway design flood for this 'Small' size dam and 'Significant' hazard potential classification is the 100 Year Flood to one-half the Probable Maximum Flood (PMF). As the dam's total capacity in nearer the lower limit of the size classification and because of the limited number of occupied structures downstream, the 100 Year Event would be an adequate spillway design flood. However, one-half the PMF has been used in this case because of the actual spillway capacity. Hydrologic and hydraulic computations presented in Appendix D indicate the spillway is capable of passing the full PMF without overtopping the embankment, resulting in an 'Adequate' spillway classification for this dam.

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 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 WOODWARD-CLYDE CONSULTANTS PLYMOUTH MEETING PA. and published by . This book was released on 1979 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Saw Mill Dam is a zoned earth embankment with an impervious core, an outer previous shell, a cutoff trench and drainage blanket and rock toe. These features are shown on Plate 3, entitled 'Typical Embankment Sections'. The dam is approximately 1,335 feet long and the height, measured from the crest to the principal spillway discharge pipe inlet, is 47 feet. Borrow materials were obtained from the spillway excavation and within the reservoir area. The core of the dam is composed of clayey materials derived from the borrow areas, and the shell is composed of more previous materials selectively excavated from the borrow pits. The 10 foot wide cutoff trench has 1H:1V side slopes and a grout cap at the base of the trench. The foundation was grouted using a single line grout curtain with six foot hole spacings. The average hole depth is 15 feet and the maximum hole depth is 30 feet. The upstream slope is 3H:1V, the lower two-thirds of the slope is protected with 18 inches of riprap over a 12-inch filter blanket and the upper portion is protected with grass. The downstream slope is 2.5H:1V and protected with grass.

Phase I Inspection Report written by John Boschuk (Jr) and published by . This book was released on 1979 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pocono Lake Dam is a concrete ogee spillway with concrete non-overflow sections keyed on each side into a zoned earth embankment. The embankment contains an upstream impervious fill protected with three feet of dumped riprap over a one foot filter bed. The facility is considered to be in good condition and well maintained. Hydrologic and hydraulic calculations indicate the dam will pass the Probable Maximum Flood without overtopping. Therefore, the spillway system is considered to be 'Adequate'. Visual inspection of the dam and reservoir detected no significant problems with the structure. There was some leakage noted around the stilling basin walls, which was assessed to be drainage from the rock toe. Some minor cracking of the spillway walls was noted and the loss of some joint sealer was noted in the bride. These conditions are not considered to be critical.

Phase I Inspection Report written by WOODWARD-CLYDE CONSULTANTS PLYMOUTH MEETING PA. and published by . This book was released on 1979 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Swiftwater Dam is a 31 + or - foot high zoned embankment containing an impervious core founded in hardpan. The embankment has upstream and downstream slopes of 2.5H:1V and a crest width of 10 feet. When the old spillway was relocated to the right abutment, the embankment section was reconstructed and is a homogeneous embankment with an eight foot wide cutoff trench founded on impervious materials. The upstream and downstream slopes were both constructed at 2.5H:1V with a 10 foot crest width. The upstream slope of the whole embankment is protected with riprap, minimum thickness being 18 inches on the new embankment and 12 inches on the old embankment. The embankment impounds a 21-acre reservoir. The embankment also contains a gatehouse tower located near the crest of the dam approximately midway along the length of the embankment. The gatehouse tower contains a steel sluice gate manufactured by the Caldwell-Wilcox Company. Documentation in the files indicates that the intake pipe is 42 inches in diameter, located at the base of the embankment, and encased in concrete with anti-seep collars.

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: East Stroudsburg Dam is a 47.5 foot high earth and rock fill embankment with a concrete core wall. The dam is located across Sambo Creek and is about 740 feet long. The structure impounds a 57-acre lake with a 914 acre-foot normal storage capacity. Available records indicate that the core wall is founded in clay or hardpan. Upstream of the core wall, embankment materials consist of compacted soils. The upstream slope is protected with hand placed riprap. The slope is 2H:1V above elevation 867 (USGS Datum) and below elevation 867 the slope increases to 2.5H:1V. The compacted fill section downstream of the core wall has a 1H:1V slope and the overlying hand placed rock section has a slope of 2H:1V with a six foot berm at approximately elevation 873. The crest elevation is 893 with a measured width of 12 feet. The gatehouse is located about 320 feet from the right abutment. The best available section of this gatehouse is shown to Plate 5, Appendix E. The sluice gates are inside the gatehouse, one for the 24-inch intake pipe and one for the 24-inch discharge pipe. The intake is located at the upstream toe and the outlet discharges at the downstream toe into a rocklined channel.

Phase I Inspection Report written by WOODWARD-CLYDE CONSULTANTS PLYMOUTH MEETING PA. and published by . This book was released on 1979 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pole Run Dam No. 4 is a 30 foot high earthen embankment across Pole Run, a tributary of North Mahanoy Creek. The 780 foot long dam impounds a nine acre reservoir within an 0.58 square mile drainage basin. Very limited data exists regarding the physical features of the dam. The average measured downstream slope is 2H:1V, and the slope is covered with stone and vegetation. Since the average freeboard of the structure is less than one foot at normal pool level, the upstream slope could not be measured. A portion of the upstream slope is covered with stone, and this stone could be seen to extend at least two feet below the water and it is probable that it extends several feet below that elevation. The crest width ranges from 15 feet to 27 feet. The spillway is located at the right abutment, and consists of an open concrete channel with concrete retaining walls. The water supply intakes could not be inspected as they are below water and the pipes are buried in the embankment. The outlet pipes were inspected and three pipes were found. Near the toe of the dam, valves were located which are presumably used to control flow through the pipes.

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 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Pine Run Dam No. 1 is based upon visual observations made at the time of inspection, review of available records and data, hydraulic and hydrologic computations and past operational performance. Pine Run Dam No. 1 appears to be in poor condition. Severe deterioration of the downstream slope, in particular, the overflow section, exists. The concrete has extensive cracks, and deteriorated portions. Seepage is passing through portions of the dam and under the spillway slabs. The mortar between the masonry blocks on the exposed downstream slope has eroded. The concrete buttresses have severely deteriorated and show stress cracks. The stability analysis conducted for this study which was based on assumed strength parameters indicates that the dam is unstable with water levels corresponding to the top of the non-overflow section (elevation 949.0). Pine Run Dam No. 1 is a high hazard-intermediate size dam. The recommended spillway design flood (SDF) for this dam is the PMF. The spillway and reservoir are capable of controlling approximately 30% of the PMF without overtopping the embankment. Based on criteria established by the Corps of Engineers, the spillway is termed seriously inadequate. If Pine Run Dam No. 1 fails due to overtopping, the hazard to loss of life and property immediately downstream of the dam would be significantly increased from that which would exist just prior to the overtopping. Pine Run Dam No. 1 is classified as an unsafe non-emergency dam. (Author).
