This book was released on 1981 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the criteria established for these studies, Elmcrest 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 100-year flood and 1/2 of the Probable Maximum flood (PMF). The selected SDF is the 1/2 PMF. The existing spillway will pass only about 40 percent of the PMF before overtopping of the dam occurs. The spillway capacity is rated as inadequate. The computed spillway capacity is, at best, a rough approximation. It is judged that there is a severe potential for collection of debris at the spillway which could reduce the spillway capacity considerably. The outlet works is only capable of discharging when the reservoir is above normal pool elevation. Access to the outlet works valve is judged to be unsuitable. No conditions of immediate concern were observed at the embankment.

This book was released on 1979 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, available records, calculations and past operational performance, Dunmore No. 1 Dam is judged to be in good condition. The spillway can pass 84 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. The spillway capacity is rated as inadequate. Two culverts, immediately downstream of the dam, may provide significant tailwater effects at the dam. If the top of the dam were raised 0.4 foot to its design elevation, the spillway can pass 90 percent of the PMF. The spillway capacity would still be rated as inadequate. Because there is no analysis available, the structural stability of the masonry gravity spillway is unknown. The spillway right training wall does not have any significant deviations from the guidelines for stability. There is no evidence of instability on the embankment.

This book was released on 1979 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marshwood Dam is two homogeneous earthfill embankments with masonry core-walls. The dam was built in a natural saddle. The embankments impound water within the saddle. The dam has a main spillway and an auxiliary spillway. The main spillway is located at the right abutment of the South Embankment. It has a sharp-crested concrete weir with a crest length of 100 feet. The auxiliary spillway is a canal about 300 feet left of the South Embankment. Based on visual inspection, available records, calculations and past operational performance, Marshwood Dam is judged to be in fair condition. The spillway can pass 65 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. The spillway capacity is rated as inadequate. This rating is dependent on implementation of some of the recommendations herein. If the low areas on the embankments were raised 0.6 foot to the design elevation, the spillway can pass 80 percent of the PMF. The spillway capacity would still be rated as inadequate.

This book was released on 1979 with total page 103 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, No. 5 Dam is judged to be unsafe, nonemergency, because the spillway capacity is rated as seriously inadequate. The spillway can pass 29 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. Failure of the dam would cause an increase hazard to loss of life downstream. As a whole, the dam is judged to be in fair condition. The spillway gravity weir does not have any significant deviations from the guidelines for stability, since the toe pressure is well below the allowable. There is no evidence of instability on the embankment.

This book was released on 1980 with total page 69 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 poor condition. The dam is considered to be unsafe, non-emergency. 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 dam is the full PMF. The spillway capacity is inadequate to pass the SDF peak inflow without overtopping the dam. The project is capable of passing 95 percent of the PMF and is considered to be inadequate, but not seriously inadequate.

This book was released on 1979 with total page 100 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, Curtis Dam is judged to be unsafe, nonemergency, because the spillway capacity is rated as seriously inadequate. The existing spillway can pass 17 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. The resulting outflows from the failure of Curtis Dam would probably overtop and cause the failure of Emlhurst Dam. This would result in the loss of life. As a whole, the dam is judged to be in fair condition. If the low areas of the top of the embankment were raised 1.1 feet to the design elevation and if the low areas of the dike were raised 2.0 feet to the design elevation, the spillway could pass 46 percent of the PMF. The spillway capacity would still be rated as seriously inadequate. There is no evidence of stability problems on the embankment. The spillway and auxiliary spillway sections meet the OCE guidelines for stability. A length of the left spillway training wall has failed.

This book was released on 1979 with total page 82 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, Rocky Glen Dam is judged to be unsafe, nonemergency, because the spillway capacity is rated as seriously inadequate. The existing spillway can pass only 7 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. Because a portion of the masonry gravity dam is founded on earth and there are no erosion protection measures at the toe, it is assumed that the dam could not withstand the depth and duration of overtopping that would occur for the PMF or the 1/2 PMF. Failure of the dam would cause an increased hazard to loss of life downstream. As a whole, the dam is judged to be in fair condition. Stability studies performed as part of this report indicate that the dam does not have any significant deviations from the Office of the Chief of Engineers (OCE) guidelines for stability. Maintenance at the dam and operating facilities is inadequate. There is no program for regular inspection of the dam.

This book was released on 1979 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, available records, calculations and past operational performance, Lake Henry Dam is judged to be in good condition. The existing spillway can pass 60 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. The spillway capacity is rated as inadequate. If the embankments were raised 0.7 foot to their design elevation, the dam could pass the PMF with 0.05 foot of freeboard. The spillway capacity would then be rated as adequate. A low area between the two embankments acts as an auxiliary spillway. There is no stability analysis for the embankments. There is no evidence of significant problems threatening the embankments. The spillway weir is judged to be stable.

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.

This book was released on 1980 with total page 96 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, Spring Brook Intake Dam is judged to be in good condition. 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. Based on the criteria and the downstream conditions, the selected Spillway Design Flood (SDF) at the dam is the Probable Maximum Flood (PMF). The existing spillway will pass about 53 percent of the PMF without overtopping of the dam. The spillway capacity is rated as inadequate. If the low area on the top of the dam were filled to the design elevation, the spillway would pass about 56 percent of the PMF, and it would still be rated as inadequate. The only stability problem evident at the dam is a bulge on the upstream slope of the embankment. The main and auxiliary spillway weirs have no significant deviations from the OCE guidelines for stability of gravity structures. There are two emergency drawdown facilities at the dam. One of these facilities is operational, but because of its small size, its ability to draw down the pool is marginal. The ability of the other facility to function is uncertain.

This book was released on 1979 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Olyphant No. 3 Dam is an earthfill embankment 760 feet long and 37 feet high at its maximum section. The embankment has a puddled impervious core and riprap on both the upstream and downstream slopes. The spillway is located at the right abutment of the dam. It is an excavated, riprapped channel with irregular geometry. The invert of the channel is 2.6 feet below the design level of the top of the dam. A 12-inch diameter cast-iron pipe with a valve at the downstream end extends through the center of the embankment and regulates flows. Olyphant No. 2 Dam is 0.5 mile downstream. The dam is located on Grassy Island Creek approximately 1.7 miles east of the Village of Winton, Pennsylvania.

This book was released on 1981 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual inspection and review of available data indicate that Duck Pond Dam is in fair condition. The lack of embankment protection from spillway flows and the inadequate spillway capacity are the primary deficiencies which cause concern for the safety of this dam. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for this facility is in the range of the 100 year flood to 1/2 the Probable Maximum Flood (PMF). Based on the size of the dam and degree of downstream hazard, the selected SDF is the 100 year flood. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and outlet works discharge capacity will not pass the SDF (100 year flood) prior to overtopping the embankment. In accordance with the criteria outlined and evaluated in Section 5.5 of this report, the discharge capacity for Duck Pond Dam is considered to be inadequate.
