Shifrin and published by . This book was released on 1979 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the criteria in the guidelines, the dams are in the high hazard potential classification, which means that loss of life and appreciable property loss could occur in the event of failure. Our inspection and evaluation indicates that the spillway of Cedar Hill Lake No. 2 and No. 3 Dams meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. These dams are small size dams with a high hazard potential required by the guidelines to pass from one-half of the Probable Maximum Flood to the Probable Maximum Flood without overtopping. Considering the small volume of water impounded, and the large floodplain downstream, one-half of the PMF is the appropriate Spillway Design Flood (SDF). It was determined that the spillways will pass 55 percent of the Probable Maximum Flood without overtopping the dam. Our evaluation indicates that the spillways will pass the 100-year flood; that is, a flood having a 1 percent chance of being equalled or exceeded during any given year.

Reitz and published by . This book was released on 1978 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fon-du-lac Subdivision Dam was inspected by an interdisciplinary team of engineers. The purpose of the inspection was to make an assessment of the general condition of the dam with respect to safety, based upon available data and visual inspection, in order to determine if the dam poses hazards to human life or property. Failure would threaten the life and property of ten families and cause appreciable damage to two county roads. Our inspection and evaluation indicates the dam is deficient in that the spillway is inadequate. The guidelines for a dam having the above size and hazard potential require that the spillway be capable of passing a one-half PMF (Probable Maximum Flood). The Probable Maximum Flood is defined as the flood discharge that may be expected from the most severe combination of critical meteorologic and hydrologic conditions reasonably possible in the region. Considering the small volume of water impounded, the large floodplain downstream and the three groups of farm buildings downstream, one-half PMF is the appropriate spillway design flood. A 20% PMF will begin to overtop the dam. The lake and spillway are adequate to contain a 1% annual probability flood (100-year flood) without overtopping the dam.

Book excerpt: No-Name 249 Dam was inspected by an interdisciplinary team of engineers. The purpose of the inspection was to make an assessment of the general condition of the dam with respect to safety, based upon available data and visual inspection, in order to determine if the dam poses hazards to human life or property. Failure would threaten the life and property of four families and cause appreciable damage to associated buildings and one county road to the junction with an east-trending branch (3 miles) and 10 more families within one mile below the junction. Our inspection and evaluation indicates that the dam is deficient in that the spillway does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. Considering the potential volume of water impounded, the narrow floodplain and the four groups of buildings downstream, and the potential for future development in or near the floodplain downstream, the Probable Maximum Flood (PMF) is the appropriate spillway design flood. The Probable Maximum Flood is defined as the flood discharge that may be expected from the most severe combination of critical meteorological and hydrologic conditions reasonably possible in the region. The dam will begin to be overtopped by a flood having a discharge (peak and volume) equal to 30% of the PMF. The spillway will pass a 1% chance flood (100-year flood) without overtopping which is a flood that has a 1% chance of being exceeded in any given year.
