This book was released on 1979 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grahamville Reservoir Dam is classified as a 'Small' size-'Significant' hazard dam. The structure consists of a zoned, earthfill embankment approximately 29 feet high and 400 feet long. Based on observations made during the visual inspection, data available from the Pennsylvania Department of Environmental Resources' (PennDER) files, and information obtained from interviewing North East Borough personnel and representatives from Hill and Hill Engineers, North East; the dam is considered to be in poor overall condition. Hydraulic/hydrologic evaluations, performed in accordance with procedures established by the Baltimore District of the U.S. Army Corps of Engineers for Phase I Inspection Reports, revealed that the spillway will pass the 100-year flood without overtopping the dam. Therefore, the spillway is considered 'adequate'. It is recommended that the owner initiate a feasibility study to determine if the reservoir is necessary for meeting the water requirements of the borough or whether the effort could be better spent upgrading one of its other reservoirs to meet the requirement for potable water.

Y. Chen and published by . This book was released on 1979 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eaton Dam (also known as Bull Reservoir) is an earth embankment, straight in plan, with a spillway channel in excavation around its right end. The embankment has a maximum height of 22 feet and a length of 840 feet. The upstream slope is 3H:IV (Horizontal to Vertical), the downstream slope is 2H:IV, and the crest is 20 feet wide. The 14-inch cast-iron pipe outlet was laid in an excavation on a concrete cradle provided with concrete cutoffs. The control valve is located in a tower in the upstream slope is provided with riprap and the downstream slope is grass covered. The 20-foot wide clay core of the dam extends throughout the entire length of the embankment. Eaton Dam is located in a small drainage area tributary to French Creek, approximately 4.5 miles southeast of the Borough of North East, Erie County, Pennsylvania, less than 0.5 mile from the Pennsylvania-New York border.

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.

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 1981 with total page 99 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 good condition. In accordance with the Corps of Engineers' evaluation guidelines, the size classification of this dam is intermediate and the hazard classification is high. These classifications indicate that the Spillway Design Flood (SDF) should be the Probable Maximum Flood (PMF). The spillway capacity is adequate for passing 43 percent of the PMF peak inflow without overtopping the dam. The spillway, therefore, is considered to be inadequate, but not seriously inadequate. Some recommendations presented for immediate action by the owner are: (1) that measures shall be taken to provide an adequate spillway capacity, which shall include the raising of the embankment profile uniformly to at least its design crest elevation; (2) that the downstream toe and an area 20 feet beyond the toe be cleared on a regular basis of all brush, weeds and trees, permitting close observation of the seepage; and (3) that the slab joints in the spillway channel be filled with a joint material.

Book excerpt: The purpose is to determine if the dam constitutes a hazard to human life or property. Beaver Lake Lodge Dam is located on Raymondskill Creek in Milford Township, Pike County, Pennsylvania. The visual inspection of the facility suggested that the dam and its appurtenances are in poor condition. The overall appearance of the facility suggests it to be in poor condition. Remedial measures are necessary to: (1) repair to deteriorated concrete spillways, (2) remove the trees and overgrowth from the embankment crest and slopes, (3) provide adequate erosion protection along the downstream embankment toe, and (4) restore the operability of the outlet conduit, or provide an alternate means of reservoir drawdown.

Hannan and published by . This book was released on 1980 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a review of available design information and visual observations of conditions as they existed on the date of the field inspection, the general condition of the Breskin Dam No. 2 is considered to be good. The structure is classified as an 'intermediate' size, 'high' hazard dam and the Spillway Design Flood is the Probable Maximum Flood. The spillway capacity was found to be 'inadequate' because the non-overtopping flood discharge capacity, as estimated using the HEC-1 computer program, was found to be 42 percent of the PMF. The spillway is not 'seriously inadequate', because in the opinion of the evaluating engineer, the dam will not fail at 50 percent of the PMF.

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 1980 with total page 85 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 about 77 percent of the PMF prior to embankment overtopping. Consequently the spillway is assessed as being inadequate, but not seriously inadequate. Deficiencies noted by the inspection team included the following: (1) large trees rooted within the downstream embankment face; (2) a damaged and inadequate spillway discharge channel; and (3) a bent gate stem and partially obstructed outlet associated with the blowoff conduit.

Dziubek and published by . This book was released on 1980 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Jo-Ann Dam, formerly known as Bracco Dam, is classified as a 'High' hazard - 'Small' size dam. The dam and reservoir, owned by Mr. Daniel Carapellucci, Sr., are used for recreational purposes. The dam was found to be in fair overall condition at the time of the 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 spillway will pass 27.5 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 Lake Jo-Ann Dam. Because the dam is on the low end of the 'Small' size category, the 1/2 PMF was selected as the SDF. It was determined that during the 1/2 PMF the embankment would be overtopped by a maximum depth of 0.89 foot and a total duration of 5.00 hours. Because a limiting criteria of one foot or greater of overtopping and duration in excess of 2 hours was estimated for this dam, it was concluded that a dam failure during the 1/2 PMF is unlikely to occur.
