Dziubek and published by . This book was released on 1980 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parker Dam is classified as a 'Significant' hazard - 'Small' size dam. The dam and reservoir, owned by the Commonwealth of Pennsylvania, Department of Environmental Resources, are used for recreational purposes. The dam and appurtenant structures were found to be in good overall condition at the time of the inspection. A spillway design flood (SDF) in the range of the 100-year flood to the 1/2 Probable Maximum Flood (1/2 PMF) is required for Parker Dam. Since the dam is in the middle of the 'Small' size category according to storage capacity, the 1/2 PMF was selected as the SDF. Hydrologic/hydraulic evaluations, performed in accordance with procedures established by the Baltimore District of the U.S. Army Corps of Engineers, revealed that the available spillway capacity is much greater than the maximum flow expected during the SDF. Therefore, the dam will not be overtopped during the SDF and the spillways are considered to be 'adequate'.

Mihalcin and published by . This book was released on 1980 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and available engineering data, the dam is considered to be in good condition. The size classification of the facility is small and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Due to the high potential for damage to downstream structures and possibly loss of life, the SDF is considered to be the PMF. Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store approximately 92 percent of the PMF prior to embankment overtopping. Based on screening criteria contained in the recommended guidelines, the spillway is considered to be inadequate, but not seriously inadequate. Deficiencies noted by the inspection team included a seepage condition along a portion of the downstream embankment toe approximately 160 feet to the right of the left abutment hillside and a minor vertical crack in the concrete spillway overflow wall.

Dziubek and published by . This book was released on 1980 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: PA 483 is a 74-foot high, zoned-earthfill floodwater retarding dam designed by the U.S. Department of Agriculture, Soil Conservation Service (SCS). The dam is owned and operated by the Washington County Commissioners. The dam consists of a 360 foot long embankment, a vegetated earth side channel emergency spillway, and an intake riser and outlet conduit (principal spillway). The dam and appurtenant structures were found to be in good overall condition at the time of the inspection. Hydraulic/hydrologic evaluations revealed that the spillway will pass the Probable Maximum Flood (PMF) without overtopping the dam. PA 483 is a 'High' hazard, 'Intermediate' size dam requiring evaluation for a spillway design flood (SDF) equal to the PMF. Therefore, the spillway is assessed as 'adequate.' The inspection revealed certain items of remedial work which should be performed immediately by the owner.

This book was released on 1980 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Upper and Lower Dams consist of two dams in series designed by the U.S. Department of Agriculture, Soil Conservation Service (SCS) for floodwater detention and waterfowl habitat enhancement. Lower Dam is the primary structure upon which this report focuses because the majority of Upper Dam becomes inundated by backwater from Lower Dam before the emergency spillways at Lower Dam are activated. Hydraulic/hydrologic evaluations revealed that the spillways will pass the Probable Maximum Flood (PMF) without overtopping Lower Dam. A spillway design flood (SDF) equal to the PMF is required for Lower Dam. Therefore, the spillways are considered 'adequate.' The inspection revealed only one deficiency which should be corrected immediately, namely, the repair of the chipped concrete on the impact basin of Upper Dam.

Dziubek and published by . This book was released on 1980 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: PA 485 is a zoned earthfill embankment with a total length of 630 feet, including the emergency spillway on the left abutment. The height and crest width of the embankment are 78 feet and 14 feet, respectively. The embankment was constructed using three zones of fill material. The principal spillway is a drop-inlet structure consisting of a two stage reinforced concrete riser connected to a 30 inch diameter reinforced concrete outlet pipe. The emergency spillway for the dam is located at the left abutment. It consists of a vegetated trapezoidal channel with a bottom width of 50 feet and 2H:1V side slopes. Hydrologic/hydraulic evaluations revealed that the spillway will pass the Probable Maximum Flood (PMF) without overtopping the dam. A spillway design flood (SDF) equal to the PMF is required for PA 485. The spillway is therefore considered to be 'adequate'. The visual inspection revealed several minor deficiencies which require remedial action by the owners of the dam.

This book was released on 1980 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: The general condition of the Treated Water Pond is considered to be fair. This assessment is based primarily on visual observations of embankment conditions and lack of information on the structural capacity of conduits through the embankment. The structure is classified as an 'intermediate' size, 'high' hazard dam. Corps of Engineers guidelines recommend the Probable Maximum Flood (PMF) as the Spillway Design Flood for an 'intermediate' size, 'high' hazard dam. The Treated Water Pond's Spillway Design Flood is the Probable Maximum Flood. Spillway capacity is 'adequate' because the non-overtopping flood discharge was found, by using the HEC-1 computer program, to be in excess of 100 percent of the PMF. The visual inspection indicates several minor deficiencies in addition to those requiring further investigation. The deficiencies can be corrected or improved through implementation of the following recommended evaluation, remedial, monitoring and/or maintenance efforts.

This book was released on 1980 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Martindale Dam, owned and operated by the Borough of Portage Water Authority, is classified as a 'Small' size - 'High' hazard dam. The dam was found to be in fair overall condition at the time of inspection. Hydraulic/hydrologic evaluations, performed in accordance with procedures established by the Baltimore District, Corps of Engineers, for Phase I Inspection Reports, revealed that the dam, reservoir, and spillway will pass 16 percent of the Probable Maximum Flood (PMF) before overtopping of the dam occurs. A spillway design flood (SDF) in the range of the 1/2 Probable Maximum Flood (1/2 PMF) to the PMF is required for Martindale Dam. The 1/2 PMF was chosen as the SDF because the dam is on the low end of the 'Small' size category in terms of its storage and height. During the 1/2 PMF, the maximum depth and total duration of overtopping are 0.83 feet and 8.5 hours, respectively. Due to the relatively narrow crest width of the dam and the long duration of overtopping, it was judged that failure of the dam is likely during the 1/2 PMF. To assess the increase in damages downstream from the non-failure cases, the 1/2 PMF was routed through the dam and downstream for both conditions. It was determined that there would be a significant increase in economic damages and possible loss of life if the dam failed. The spillway is therefore categorized as being 'seriously inadequate.'

This book was released on 1979 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam consists of a zoned, earthfill embankment that is 590 feet long and 52 feet high at its maximum section. The main spillway is a drop spillway located near the right abutment of the dam. It consists of a concrete riser connected to a 30-inch diameter reinforced concrete pipe under the embankment. The auxiliary spillway is an excavated channel along the left abutment of the dam. It is a grass-linked excavation in earth. Based on visual inspection, available records, calculations and past operational performance, PA-467 Dam is judged to be in good condition. The existing spillway can pass the Probable Maximum Flood(PMF) without overtopping of the dam. The spillway capacity is rated as adequate. There is a slope stability analysis for the embankment, and it indicates that the embankment has adequate factors of safety. There is no evidence of significant problems threatening the embankment.
