This book was released on 1978 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, available records, calculations and past operational performance, Mill Creek Dam is judged to be in good condition. However, the spillway (main and auxiliary) will not pass the Probable Maximum Flood (PMF) without overtopping the dam. Therefore, based on criteria established for these studies by the Department of the Army, Office of the Chief of Engineers (OCE), the spillway capacity is rated as inadequate. The spillway will pass one-half the PMF without overtopping the dam. Therefore, based on the OCE criteria established for these studies, the spillway capacity is not rated as seriously inadequate. The existing spillway can accommodate a flood with a peak inflow of 67 percent of the PMF peak flow. The spillway capacity is controlled by the elevation of a low area on the top of dam near the spillway. If the top of the dam were brought up to the design elevation, the spillway would accommodate a flood with a peak inflow of 118 percent of the PMF peak inflow. The spillway would then be rated as adequate. (Author).

This book was released on 1980 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Brown Creek Dam is based upon visual observations made at the time of inspection, review of available records and data, hydraulic and hydrologic computations and past operational performance. The Brown Creek Dam appears to be in fair condition. The erosion on the crest and downstream embankment in the area of the principal spillway and along the wingwall of the emergency spillway crest should be repaired. Because the reservoir was dry (as is the normal condition) no determination as to potential wet zones or seepage areas could be made. Maintenance of the dam and operating facilities is considered fair. The Brown Creek Dam is a high hazard-small dam. The recommended spillway design flood (SDF) for this dam is the 1/2 PMF to PMF. Based on the potential for downstream loss of life, the spillway design flood has been selected as the PMF. The spillway and reservoir are capable of controlling approximately 80% of the PMF without overtopping the embankment (low spot). Based on criteria established by the Corps of Engineers, the spillway is termed inadequate.

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.

Jeffrey Kimball and published by . This book was released on 1980 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lake of the Four Seasons Dam consists of two earthfill impounding structures. The main embankment (dam) is an earthfill dam, 1500 feet long and 29 feet high. At the left abutment of the main embankment (dam) are two spillways. One spillway consists of a concrete culvert type spillway, modified to function as an orifice. Immediately adjacent to the concrete structure at the left abutment is an open earth cut channel which serves as a temporary auxiliary spillway for the dam. The second impounding structure (dike) is located approximately 1/2 mile southwest of the main embankment. The dike is approximately 600 feet long, and 26 feet high. A permanent concrete ogee spillway is located approximately 500 feet southwest of the dike on the left abutment. The spillway and reservoir are capable of controlling approximately 54% of the PMF. Definitions used by the Corps of Engineers indicate that the spillway should be rated as inadequate. However, the temporary and permanent (as designed) auxiliary spillway has the potential for erosion of the exit channel and subsequent erosion of the toe of dam. It is possible that a failure of the dam could result at less than 1/2 PMF by erosion of the embankment toe.

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.

This book was released on 1980 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: SCS PA 477 is a 52-foot-high, 1,550-foot-long dam. The embankment contains an impervious core constructed over a cutoff trench under the dam centerline. About 1,270 feet of the embankment is roughly parallel to U.S. Route 22/Interstate 78. The remaining 280 feet of the embankment forms an angle of about 60 degrees with the highway. The shorter leg contains the maximum section and the principal spillway. The principal spillway consists of a concrete drop inlet riser, a 222 foot long, 30 inch reinforced concrete pipe with eight anti-seep collars, and an impact basin. The emergency spillway was excavated through rock at the right abutment. The grass-lined trapezoidal channel is approximately 150 feet wide and 30 feet wide. The dam and its appurtenant facilities are considered to be in good condition. Calculations indicate that the existing spillway systems are capable of passing the Probable Maximum Flood (PMF) without overtopping. Therefore, the spillway system is considered to be adequate.

This book was released on 1980 with total page 100 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. 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 possible loss of life that could be associated with a sudden breach of the embankment, the SDF is considered to be the PMF. Results of hydrologic and hydraulic analysis indicate the spillway for Wadham Creek Dam is capable of passing and/or storing the PMF. Consequently, the spillway is considered adequate.
