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.

This book was released on 1979 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Naomi Dam originally built in 1895, is owned by the Pocono Pines Corp. and serves as a recreation lake for the organization. The dam is classified as a 'Significant' hazard structure based on its potential to cause extensive property damage downstream and the remote chance for loss of life in the event of failure. The dam is also classified as an 'Intermediate' size dam by virtue of its 1,492 acre-foot normal storage capacity. On the basis of the visual inspection on 10 May 1979, and available documentation, the dam and its appurtenant structures are considered to be in good condition. Specifically, the inspection of the dam detected no significant problems with the embankment. The main spillway was assessed to be in fair condition. The auxiliary spillway, although not used very often, showed signs of leakage through the downstream toe and appears highly susceptible to erosion based on the visual inspection. Since the very limited design documentation and visual inspection was insufficient to evaluate the stability of the dam and its appurtenant structures, additional investigations are required for a comprehensive evaluation.

This book was released on 1979 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bradys Lake Dam is owned by the Pennsylvania Game Commission. The dam was built in 1914 over a preexisting dam, Lower Dorney Dam, and was reconstructed in 1961 by the Pennsylvania Fish Commission. The facility is considered to be in fair condition. The dam is classified as a 'High' hazard structure consistent with its potential in the event of failure to cause extensive property damage and possible loss of life to residents in the Arrowhead Lake development. The dam is classified as an 'Intermediate' size dam by virtue of its 1,213 acre-foot normal storage capacity. Design documentation was extremely limited. There were no as-built drawings and records indicate that, by today's standards, compaction of the embankment would have been considered, at best, marginal. However, the embankment slopes appear to be reasonable; there were no observed signs of slope instability and the embankment has performed satisfactorily for 65 years. Therefore, the embankment is at least marginally stable.

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.

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.

This book was released on 1980 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on available records, visual inspection, calculations, and past operational performance, Lake Jamie Dam is judged to be in fair condition. The recommended Spillway Design Flood (SDF) for the size and hazard classification of the dam varies between the 1/2 Probable Maximum Flood (PMF) and the PMF. Based on the criteria and the downstream conditions, the selected SDF at the dam is the PMF. Based on existing conditions, the spillways will pass about 46 percent of the PMF before overtopping of the dam occurs. However, it is judged that the dam could just withstand the depth and duration of overtopping that would occur for the 1/2 PMF. If the low areas on the top of the embankment were filled to the design elevation, the spillways would pass about 77 percent of the PMF. For either condition, the spillway capacity is rated as inadequate, but not seriously inadequate. The steep downstream slope and the seepage at the dam indicate that the embankment stability may be marginal for the normal operating condition. The main spillway weir is judged to be stable. The ability of the emergency drawdown facility to function is uncertain. The dam has significant deviations from the design data. Maintenance at the dam needs to be improved. (Author).

This book was released on 1979 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trout Lake Dam is an earth embankment dam with a concrete overflow spillway. The dam is approximately 390 feet long and has a maximum height of about 24 feet. The dam is located along Pennsylvania Route 715, about 1 mile south of Reeders, Pennsylvania. The spillway is capable of discharging 25 percent of the Probable Maximum Flood (PMF) without overtoppong of the earth embankment. Failure of the dam would significantly increase the hazard to loss of life downstream of the dam. Therefore, the spillway is classified as 'seriously inadequate' and the dam is classified as 'unsafe(non-emergency)'. The spillway capacity should be increased. Further detailed hydrologic and hydraulic studies should be performed prior to the design of additional spillway capacity. Based on visual observations and review of the information obtained from the Pennsylvania Department of Environmental Resources, Dam Safety Section, Trout Lake Dam is considered to be in poor condition.

This book was released on 1980 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Tobyhanna Lake No. 2 Dam 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. The inspection and review of data of Tobyhanna Lake No. 2 Dam did not reveal any problems which would require emergency action. The dam and spillway appear to be in good condition and are adequately maintained. Tobyhanna Lake No. 2 Dam is a high hazard-intermediate size dam. The spillway design flood (SDF) for a dam of this size and classification is the PMF. The spillway and reservoir are capable of controlling approximately 58% of the PMF. Based on criteria established by the Corps of Engineers, the spillway is termed inadequate.

Book excerpt: Based on visual inspection, available records, calculations and past operational performance, and according to criteria established for these studies, Mountain Springs Lake Dam is judged to be unsafe, non-emergency, because the spillway capacity is rated as seriously inadequate. The existing spillway will pass only about 10 percent of the Probable Maximum Flood (PMF) before overtopping of the dam occurs. It is judged that the dam could not withstand the depth and duration of overtopping that would occur for the 1/2 PMF. Failure of the dam would cause an increased hazard for loss of life downstream. As a whole, the dam is judged to be in fair condition. No stability problems were evident for the dam or appurtenant structures. The ability of the outlet works to function is unknown. There are no known upstream closure facilities. Maintenance of the dam is not adequate. Both the dam and the dike are overgrown with trees.

Mihalcin and published by . This book was released on 1981 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monroe Lake Dam is located on Bear Swamp Run, a tributary to Marshall Creek, in Middle Smithfield Township, Monroe County, Pennsylvania. The facility is less than five miles north of the community of Marshalls Creek, Pennsylvania and approximately eight miles north of the city of East Stroudsburg, Pennsylvania. Observations made during the visual inspection indicate the embankment is in fair condition. The structure is characterized as very irregular and poorly aligned both horizontally and vertically. The downstream embankment toe is partially inundated by water that may be attributable to seepage through the embankment and/or leakage through or around the conduit. The water is trapped in a trough area between the embankments of the dam and the downstream roadway. The condition may be exaggerated because the drainage culvert under the road appears to be partially obstructed. Minor erosion was observed along both the upstream and downstream dam faces. Although particularly evident along the upstream slope adjacent the outlet riser and along the steepest portions of the downstream slope, the erosion is not considered to be significant at this time. Field measurements indicate low areas along the embankment crest between one-half and two feet below the elevation of the left spillway wingwall. The crest is covered with gravel and the slopes with weedlike vegetation.

This book was released on 1980 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, available records, calculations, and past operational performance, Pinetree Lake Dam is judged to be in good condition. The recommended Spillway Design Flood (SDF) for the size and the hazard classification of the dam varies between the 100-year flood and the 1/2 Probable Maximum Flood (PMF). Based on the criteria and the downstream conditions, the SDF is the 1/2 PMF. The spillway will pass the PMF with 0.5 foot of freeboard. The spillway capacity is rated as adequate. No stability problems were evident for the embankment. None of the observed deficiencies at the dam were considered an immediate hazard.

This book was released on 1980 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, available records, calculations, past operational performance, and according to criteria established for these studies, Middle Dam is judged to be unsafe, non-emergency because the spillway capacity is rated as seriously inadequate. Under existing conditions, the spillway can pass only about 22 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. If low areas on the top of the dam were filled to the design elevation for the top of the dam, the spillway would pass about 33 percent of the PMF. For either condition, it is judged that the dam could not withstand the depth and duration of overtopping that would occur for the 1/2 PMF. Failure of the dam would cause an increased hazard for loss of life downstream. As a whole, the dam is judged to be in fair condition.

This book was released on 1979 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Skytop Dam is a 19 foot high zoned embankment with an 18 foot high concrete core wall. The dam impounds a 68-acre reservoir. The embankment downstream of the core wall is composed of a porous gravelly material. The downstream slope is 2H:1V. Immediately upstream of the core wall is a triangle-shaped impervious zone. The remaining portion of the upstream zone is composed of a 'dirty' gravel and protected with hand-placed riprap. The upstream slope is 2H:1V. The crest is 24 feet wide. The structure has a gatehouse located at the upstream toe. The gatehouse tower contains a wooden sluice gate with a screened entrance, and a 'Wilcox' gate valve inside the tower, which allows water to enter a 24-inch cast iron pipe. The 24-inch blow off pipe discharges at the downstream toe into the middle of the three lakes, Skytop Dam being the upper and largest of the three lakes on this property.
