Mihalcin and published by . This book was released on 1979 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection and hydrologic/hydraulic analysis the overall condition of the facility is considered to be fair. The size classification of the facility is small and the hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Results of the hydrologic/hydraulic analysis indicate the facility will discharge and/or store only 24 percent of the PMF prior to overtopping of the embankment. Overtopping is expected to cause embankment failure, with the breaching analysis indicating that failure will probably result in an increase to potential for loss of life downstream of the facility. Therefore, the spillway system is considered to be seriously inadequate, and the facility unsafe, non-emergency. Deficiencies noted by the inspection team included seepage and swamp-like conditions immediately downstream of the embankment toe and around the outlet conduit, heavily overgrown outlet and spillway discharge channels, an erosion ditch extending from the right abutment hillside to the downstream embankment toe along the embankment-abutment contact, deteriorated spillway concrete, several unvegetated areas along the embankment and adjoining spillway dike, and a submerged outlet conduit riser and control valve.

This book was released on 1979 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recreation Dam is an L-shaped earth dam with a measured maximum height of 14.7 feet and a total length of approximately 1,600 feet. The facility is provided with a masonry spillway at the left abutment along its northern section and a diversion canal along its easterly extension. The latter serves to divert acid mine drainage from upstream mined areas around the facility. Based on visual observations, past history, and a hydrologic and hydraulic investigation, the dam and its appurtenances are considered in poor condition. Based on a visual evaluation and past performance the spillway system is considered structurally unsafe but of non-emergency status as the reservoir is completely drawn down. In addition, evaluation of the flashboard system indicated that failure of the flashboards under normal operating procedures could in itself cause serious downstream consequences.

This book was released on 1980 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shickshinny Lake Dam is an earthfill dam, 365 feet long and 33 feet high. The crest width of the dam is 17 feet. The upstream slope is 3H:1V and the downstream slope is 2.5H:1V. Both the upstream and downstream slopes are grass covered. Some riprap exists on the upstream slope. The principal spillway consists of a reinforced concrete riser and a 30 inch reinforced concrete pipe which passes under the dam. The top of the riser unit is provided with an anti-vortex device. A gate valve is provided on an inlet pipe just inside the riser unit. Based on our hydraulic and hydrologic analysis it was determined that the spillway and reservoir are capable of controlling approximately 52% of the PMF. Based on criteria established by the Corps of Engineers, the spillway is termed inadequate. No major deficiencies were observed during the inspection. Seepage was noted at the left abutment contact and did not appear to be excessive. Erosion was observed at the outlet structure for the spillway and drainline.

Michalcin and published by . This book was released on 1980 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and available engineering data, the facility is considered to be in good condition. The size classification of the facility is intermediate and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility is the PMF (Probable Maximum Flood). Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store only about 45 percent of the PMF prior to embankment overtopping. A breach analysis indicates that failure under less than 1/2 PMF conditions could lead to increased downstream damage and potential for loss of life. Thus, based on screening criteria provided in the recommended guidelines, the spillway is considered to be seriously inadequate and the facility unsafe, non-emergency. Calculations also indicate that if the spillway were constructed in accordance with available desing drawings, the facility could pass and/or store approximately 63 percent of the PMF.

Jeffrey Kimball and published by . This book was released on 1980 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Louise Dam appears to be in poor condition. Lake Louise Dam is a high hazard small size dam. The spillway design flood is in the range of 1/2 PMF to PMF. The spillway design flood was selected to be the PMF (probable maximum flood) based on downstream potential for loss of life and property damage. The spillway is capable of controlling approximately 45% of the PMF. The dam breach analysis indicated that a significant increase in the downstream potential for loss of life and property damage exists should the dam fail. Based on criteria established by the Corps of Engineers, the spillway is termed seriously inadequate. The spillway exit and entrance channels are in poor condition. The heavy vegetation creates the potential for water infiltration and made visual inspection of the embankment difficult. Lake Louise Dam is classified as an unsafe non-emergency dam.

Beck and published by . This book was released on 1980 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mill Water Pond Dam is owned by the Bethlehem Mines Corporation. The dam was originally built as an industrial water supply dam for the Grace Mine. As the mine is no longer in operation, water from the reservoir is no longer used. The dam and its appurtenant facilities are considered to be in good condition. The dam is classified as a Small size structure with a High hazard classification, consistent with the dam's location immediately above an occupied dwelling and above commercial buildings and other residences farther downstream on Conestoga Creek. In accordance with criteria established by Federal (OCE) Guidelines, the spillway design flood for this Small size dam and High hazard classification is one-half to the full Probable Maximum Flood (PMF). As the dam height and total capacity are near the lower limit of the size classification, the selected spillway design flood is one-half the PMF. Mining of the deep iron ore body has caused extensive subsidence. The mine waste rock is disposed of downstream of the subsidence area. Therefore, currently, Mill Water Pond intercepts surface runoff only from about 0.31 square mile immediately above the dam. Hydrologic and hydraulic computations presented in Appendix D indicate the maximum spillway capacity is greater than the peak PMF inflow from the reduced watershed. Therefore, the spillway system of this structure is considered to be Adequate.

Mihalcin and published by . This book was released on 1979 with total page 83 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 fair condition. Structural deficiencies noted during the inspection include an inoperable drawdown mechanism, seepage and ponded conditions at the downstream toe, dense overgrowth (bushes, weeds, small trees) on the down stream slope, and minor concrete deterioration in the spillway. The size classification of the facility is intermediate and its hazard classification is considered to be significant. In accordance with recommended guidelines, the Spillway Design Flood (SDF) for this facility is 1/2 the Probable Maximum Flood (PMF). Results of the hydrologic and hydraulic analysis indicate that the facility can accommodate approximately 32 percent of the PMF and/or 64 percent of SDF (1/2 PMF). Thus, the spillway system is considered inadequate, but not seriously inadequate.

This book was released on 1981 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maple Lake Dam is an earthfill embankment 14.4 feet high and 283 feet long, excluding spillway. The emergency spillway is located at the left abutment, consisting of an earth channel having a trapezoidal cross section. The bottom width of the spillway at the reservoir outlet is 56 feet. A service spillway, consisting of a 12-inch riser pipe and an 8-inch diameter outlet pipe, is located approximately 100 feet from the right abutment. The outlet works was reported to consist of an 8-inch diameter asbestos cement pipe, extending upstream of the riser pipe to the reservoir and terminating with two sections of an 8-inch diameter vitrified clay pipe, having a concrete plug at the inlet. Based on visual inspection, the Maple Lake Dam is judged to be in good condition. Under the present conditions, the spillway will pass approximately 37 percent of the PMF. Should the top of the dam be restored to its design elevation, the spillway could pass the SDF without overtopping the dam.
