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 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.

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 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 1981 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Dam is a 23.5-foot high, 1,100-foot long earth embankment, constructed in 1969 to impound water for recreational use. The dam has an average crest width of 14 feet and a typical downstream slope of 2.5H:1V. The upstream face of the dam slopes at approximately 3H:1V and is protected with random size loose riprap. The principal spillway, including the low level outlet system, is located near the center of the dam and consists of a 4-foot square drop inlet structure, an 18-inch square low level sluice gate, and a 30-inch diameter corrugated metal pipe, which conveys discharge from the intake structure to the principal spillway discharge channel. A 75-foot wide emergency spillway is located at the northeastern dam abutment. Based upon the visual inspection of the dam and review of the drawings, the dam is considered to be in poor condition.

This book was released on 1981 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the criteria established for these studies, Pocono Highland Dam is judged to be unsafe, nonemergency, because the spillway capacity is seriously inadequate. The recommended Spillway Design Flood (SDF) for the size and hazard classification of the dam varies between 1/2 of the Probable Maximum Flood (PMF) and the PMF. The selected SDF is the 1/2 PMF. The existing spillway will pass only about 6 percent of the 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. If the low areas on the top of the dam were filled to the design elevation, the spillway would pass about 11 percent of the PMF without any overtopping. For either condition, the spillway capacity is rated as seriously inadequate. Failure of Pocono Highland Dam would cause an increased hazard for loss of life downstream.

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.

This book was released on 1980 with total page 92 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, Shawnee Dam is judged to be unsafe, non-emergency, because the spillway capacity is rated as seriously inadequate. The existing spillway will pass only about 38 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. If the low area on the top of the dam were filled to the design elevation, the spillway would pass only about 41 percent of the PMF, and it would still be rated as seriously inadequate. 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 poor condition. No stability problems were evident for the embankment at the time of the visual inspection, but a potential hazard exists due to significant seepage at and near the toe of the dam. The spillway weir meets recommended guidelines for stability under the normal operating condition, but not under the assumed maximum loading condition. Under the assumed maximum loading, the ability of the weir to resist failure by sliding is questionable. Erosion of material that has occurred at the toe of the weir adversely affects the stability of the structure.

This book was released on 1981 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sun Valley Dam is owned by the Sun Valley Lake Corporation and is used for private recreational purposes. The spillway is in good condition and the embankment and emergency spillway are in poor condition. Internal piping may be acting to diminish the overall stability of the dam. In accordance with criteria established by Federal (OCE) Guidelines, the recommended spillway design flood for this 'Small' and 'Significant' hazard classification is the 100-year flood to one-half the Probable Maximum Flood. Based on the small capacity of the reservoir and the limited downstream development, the 100-year event has been selected as the spillway flood. Hydrologic and hydraulic computations indicate that the spillway structure is not capable of discharging the 100-year event. Thus, the spillway facilities of Sun Valley Dam are considered to be 'Inadequate'.

This book was released on 1981 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wigwam Lake Dam is located on Wigwam Run in Stroud Township, Monroe County, one mile east of Bartonsville, Pennsylvania. The original purpose of the impounded water was for ice making and recreation. Presently, the lake is being used for recreation. The overall appearance of the dam and its appurtenant structures is considered to be poor. The locations of observed deficiencies are shown on the Sketch Plan. The profile and typical sections of the dam are presented, and are based on field survey made on the day of inspection. The survey datum for this inspection was an approximate elevation obtained for the spillway crest from a USGS map. The construction drawings for the dam and appurtenant structures are shown. The elevations shown on the construction drawings are based on a different datum than that of the USGS map. Therefore, to convert the elevations shown on the appended construction drawings to the elevations used in this report, it is necessary to add 609 feet to the elevations shown on the appended drawings. On the inspection date (11/26/80), the lake level was 0.1 foot above the spillway crest (elevation 708 above mean sea level). Deficiencies observed during the field inspection are describes. Visible features of the dam are depicted in photographs.
