This book was released on 1981 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marshall Lake Dam is an earthfill embankment approximately 9 feet high and 305 feet long, including spillway. The spillway is located at the right abutment, consisting of an 80 foot long and 1.5 foot wide concrete weir. The weir intersects the slope of the right abutment and terminates at a vertical concrete endwall on the earthfill dam embankment. The outlet works consist of a 24-inch diameter steel pipe with no visible upstream or downstream controls. Based on visual inspection, Marshall Lake Dam is judged to be in poor condition. Under the present conditions, the spillway will pass approximately 4 percent of the PMF without overtopping the dam.

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 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 1981 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on available records, visual inspection, calculations, and past operational performance, Lake Paupackan Dam is judged to be in fair condition. Considering the size and hazard classification of the dam, the recommended Spillway Design Flood (SDF) varies between the 1/2 Probable Maximum Flood (PMF) and the PMF. The 1/2 PMF was, in this case, selected as the SDF. The spillway and reservoir, under existing conditions, will pass approximately 19 percent of the PMF before overtopping of the dam occurs. The spillway is, therefore, rated as inadequate.

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 1981 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and hydrologic and hydraulic analysis, the dam is considered to be in fair 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. Since the facility is classified near the upper bounds of the small category with regard to available storage capacity, the SDF is considered to be the PMF. Results of the hydrologic and hydraulic analysis indicate that under existing conditions the facility will pass and/or store only about 17 percent of the PMF prior to embankment overtopping at the low area adjacent the left abutment. If the low area were regraded to the design top of dam, the spillway system would then pass about 28 percent of the PMF prior to embankment overtopping. Under existing conditions, spillway discharges are controlled by the existence of a township-owned roadway embankment and culvert that is situated about 100 feet downstream of the spillway weir.

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 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).

This book was released on 1981 with total page 75 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, Wildwood Lake Dam is judged to be in fair condition. Based on the size and hazard classification of the dam, the Spillway Design Flood (SDF) at the dam varies between 1/2 the Probable Maximum Flood (PMF) and the PMF. Based on the downstream conditions, the selected SDF is the PMF. Under existing conditions, the spillway will pass about 48 percent of the PMF without overtopping of the dam. It is judged that the dam could withstand the depth and duration of overtopping that would occur during 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 62 percent of the PMF without any overtopping. For either condition, the spillway capacity is rated as inadequate.

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 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).
