This book was released on 1980 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hallowood Lake Dam is a homogeneous, earthfill embankment. It is 31 feet high at its maximum section and 595 feet long. The spillway is located at the right abutment. The spillway consists of an approach channel, a concrete weir, an outlet channel, and a stilling basin. The crest length of the spillway is 55.0 feet. Based on visual inspection, available records, calculations, past operational performance, and according to criteria established for these studies, Hallowood Lake Dam is judged to be in good condition. The spillway will pass about 82 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. No stability problems were evident for the embankment or the appurtenant structures at the time of the visual inspection. The ability of the outlet works to function is unknown because it has not been recently operated. Maintenance of the dam and appurtenant structures is considered inadequate.

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 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lynchwood Lake Dam is 1,685 feet long and 20 feet high at its maximum section. The dam has an irregular alignment and consists of a rock-filled, timber crib dam about 1,275 feet in length, flanked on each end with reaches of embankment. A dry, stone masonry wall is located along the downstream side of the timber crib section, and there is an earthfill section upstream from the timber crib. The main spillway is located in the timber crib section of the dam near the original stream bed location. It is a broad crested weir with three concrete steps. The auxiliary spillway consists of a reach of earthen embankment lined with concrete on its downstream side and with riprap on its upstream side. The crest is protected by vegetation. Based on visual inspection, available records, calculations, past operational performance, and according to criteria established for these studies, Lynchwood Lake Dam is judged to be unsafe, non-emergency, because the spillway capacity is rated as seriously inadequate. The existing spillways can pass only 14 percent of the Probable Maximum Flood (PMF) before general overtopping of the dam occurs.

This book was released on 1980 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on avaliable records, visual inspection, calculations, and past operational performance, Brown's Lake Dam is judged to be in poor condition. Based on the size and hazard classification of the dam, the recommended Spillway Design Flood is the Probalble Maximum Flood (PMF). The spillway can pass about 82 percent of the PMF. Since the dam cannot pass the PMF but can pass the 1/2 PMF, the spillway capacity is rated as inadequate. Deficiencies exist that are considered to be pertinent to the stability of the dam. The deficiencies include the following: seepage, steep slopes, a depression on the top of the dam, growth of trees on the dam, and holes and a depression on the downstream slope of the dam. The type of design and methods of construction increase the concern for the deficiencies. The condition of the outlet works is unsatisfatory. There are no upstream closure facilities. Maintenance of the dam is inadequate. (Author).

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.

Rader and published by . This book was released on 1980 with total page 81 pages. Available in PDF, EPUB and Kindle. 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.

This book was released on 1980 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maple Lake Dam is a homogeneous, earthfill embankment. It is 35 feet high at its maximum section and 685 feet long. The main spillway is located at the maximum section of the dam. It consists of a reinforced concrete riser structure near the upstream toe of the dam, a 24-inch diameter conduit, and a concrete outlet structure at the downstream toe of the dam. The auxiliary spillway is an excavated, trapezoidal channel at the left abutment of the dam. Based on visual inspection, available records, calculations, past operational performance, and according to criteria established for these studies, Maple Lake Dam is judged to be in good condition. Based on existing conditions, the main and auxiliary spillways will pass an approximate minimum of 48 percent of the Probable Maximum Flood (PMF before overtopping of the dam occurs. No stability problems were evident for the embankment at the time of the visual inspection, but a potential hazard to stability exists due to erosion that might occur when there is flow in the auxiliary spillway.

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 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.

This book was released on 1980 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, past performance and the available engineering data, the dam and its appurtenant structures appear to be in fair condition. In accordance with the Corps of Engineers' evaluation guidelines, the size classification of this dam is small and the hazard classification is high. These classifications indicate that the Spillway Design Flood (SDF) should be in the range of one-half the Probable Maximum Flood (PMF) to the full PMF. The recommended SDF for this flood control structure is the PMF. The spillway capacity is adequate for passing 71 percent of the PMF peak inflow without overtopping the dam. The spillway, therefore, is considered to be inadequate, but not seriously inadequate.

This book was released on 1980 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, available records, calculations, and past operational performance, Indian Mountain Lake Dam is judged to be in fair condition. The existing spillway can pass the Probable Maximum Flood (PMF) with 0.6 foot of freeboard. The spillway capacity is rated as adequate. This analysis is predicted upon the proper functioning (failure) of the flashboards on the spillway crest. If the low areas at the top of the embankment were raised, the freeboard would increase to 1.2 feet. Needed repairs have been made to some features of the dam. There is no functional outlet works at the dam.
