Johnson and published by . This book was released on 1981 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silver Lake Dam is an earth embankment about 350 feet long and 15 feet high at its maximum section. An ungated overflow masonry spillway is located at the approximate midpoint of the embankment. Silver Lake Dam has a maximum storage capacity of 51 acre feet and a maximum height of 15 feet. The dam is therefore classified as 'Small' size structure. Because of the potential for the possible loss of a few lives and appreciable property losses in the damage area, located about 0.6 miles downstream, the dam is considered to be a 'Significant' hazard structure. The selected Spillway Design Flood (SDF) for Silver Lake Dam ('Small' size, 'Significant' hazard) is the one hundred year storm. An examination of the hydrologic and hydraulic analyses indicates that the spillway is not capable of passing the SDF without the dam being overtopped. The spillway is classified as 'Inadequate'. Based on visual observations and a review of the information obtained from the Pennsylvania Department of Environmental Resources, Silver Lake Dam appears to be in fair condition.

This book was released on 1981 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual inspection and review of available design and construction information indicate that Lake Quinn Dam is in fair condition. Deficiencies noted during the inspection included the lack of functional drawdown facilities and minor seepage through the masonry near the right abutment. Based on the size and hazard classification of the dam, the recommended Spillway Design Flood (SDF) varies between 1/2 the Probable Maximum Flood (PMF) and the PMF. The 1/2 PMF has been selected as the SDF due to the size of the dam and reservoir, and the downstream conditions. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and spillway discharge capacity will pass only 3 percent of the PMF without overtopping the dam. Overtopping the dam could cause failure, which would lead to a significant increase in downstream loss of life and property damage. Therefore, the spillway for Lake Quinn Dam is considered to be seriously inadequate, and the dam is judged to be unsafe, non-emergency.

This book was released on 1981 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arlington Lake Dam is an earth and concrete structure approximately 240 feet long with a maximum height of about 13 feet. A two stage, ungated overflow spillway system is located at the left abutment of the dam. A drop inlet spillway is located at the approximate midpoint of the embankment. Arlington Lake Dam has a drainage area of approximately 1.7 square miles and impounds a reservoir with a maximum storage capacity of about 51 acre-feet at the low point of the top of the dam. The spillway system is classified as 'seriously inadequate'. The dam is classified as 'unsafe, non-emergency'. Based on the visual observations, discussions with the owner, and information obtained from the pennsylvania Department of Environmental Resources, Division of Dam Safety, Arlington Lake Dam is considered to be in poor condition.

This book was released on 1979 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bear Creek Lake Dam is a rock filled timber crib structure approximately 325 feet long and 17 feet high at its maximum section. An ungated drop spillway with an 158-foot long sharp crested weir is located approximately 60 feet from the right abutment (looking downstream). The 80 acre lake is used for recreation by the residents of Bear Creek Village. It is unknown when the dam was constructed. In the state inspection report of April, 1915 it is stated, 'This dam was constructed a great many years ago, but it has been repaired from time to time, so that more than likely none of the original structure is now in existence.' Examination of the results of the hydrologic and hydraulic analysis indicate that the drop spillway is capable of passing 11 percent of the Probable Maximum Flood (PMF) without overtopping of the embankment. Failure of the dam would significantly increase the hazard to loss of life downstream of the dam. Therefore, the capacity of the drop spillway is classified as 'seriously inadequate.' The dam is considered to be 'unsafe (non-emergency).'

Johnson and published by . This book was released on 1981 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ingham Creek Dam, which impounds a private recreational lake, consists of an earth embankment approximately 645 feet long with a maximum height of 24 feet. The embankment has a variable top width averaging about 13 feet, a downstream slope averaging about 1.5H:1V and an unknown upstream slope below the water surface. The dam impounds a reservoir with a normal pool surface area of 12.4 acres and a storage capacity of 93 acre-feet. The spillway, located about 95 feet from the left abutment, consists of a rockfill covered with a concrete slab. It is 25 feet long at the crest, 21 feet long at the downstream end, and 25 feet wide. The spillway crest (Elev. 149.8) is one foot below the concrete spillway sidewalls. A wooden sluiceway structure with stoplogs, which is located about 50 feet left of the spillway sidewall, is 5 feet wide by 3 feet deep. It was once used to direct water to a mill downstream of the dam and is now in poor condition. The spillway Design Flood (SDF) chosen for this 'Small' size, 'Significant' hazard dam is the 100 year flood. The spillway is capable of discharging approximately 17 percent of the SDF prior to overtopping the low point of the top of the dam; therefore, it is classified as 'Inadequate'.

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 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to criteria established for these studies, Lake Henry Dam is classified as unsafe, nonemergency, because of the seriously inadequate spillway capacity, the significant seepage, and the whirlpools that have reportedly developed previously in the lake. The recommended Spillway design Flood (SDF) for the size and hazard category of the dam is the Probable Maximum Flood (PMF). The existing spillways can pass about 19 percent of the PMF before overtopping of the dam occurs. It is judged that the dam would fail during the 1.2 PMF. Failure of the dam would increase the hazard to loss of life downstream. As a whole, the dam is judged to be in poor condition.

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.

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.
