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.

This book was released on 1978 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Certain deficiencies were noticed during the visual inspection and are considered to have an adverse effect on the overall safety and future operation of the dam and spillway. The upstream slope of the dam is irregular (maximum slope ratio is approximately 1v on 1.3h) beginning at a level about 12 feet below the top of the dam. Excessive irregularities of the face of the dam are indications of instability and/or erosion, both of which are considered detrimental to the safety of the dam. A substantial cover of small trees and brush that may conceal animal burrows exists on the upstream and downstream slopes of the dam. The tree roots and animal burrows can provide a pathway for lake seepage that may develop into a piping condition. The upstream slope has a grass cover to protect it from erosion by wave action. Grass cover is not considered adequate to prevent erosion by wave action for a fluctuating lake level. Loss of material can result in instability and settlement of the dam crest. A dense growth of brush and small trees obstructs the spillway crest and outlet channel.

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.
