Lockett and published by . This book was released on 1980 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this visual inspection was to make an assessment of the general condition of the dam with respect to safety and, based upon available data and this inspection, determine if the dam poses a hazard to human life or property. The Kearney Lake Dam, according to the St. Louis District, Corps of Engineers, has a high hazard potential, meaning that if the dam should fail, there may be loss of life, serious damage to homes, or extensive damage to agricultural, industrial or commercial facilities, important public utilities, main highways, or railroads. The estimated flood damage zone, should failure of the dam occur, as determined by the St. Louis District, extends two miles downstream of the dam. Within the possible damage zone are two dwellings, a warehouse, and several other types of buildings. Those features lying within the downstream damage zone reported by the Corps of Engineers, St. Louis District, were verified by the inspection team.

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.

Sauthoff and published by . This book was released on 1981 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: The following summarizes the findings of the visual inspection and the results of certain hydrologic/hydraulic investigations performed under the direction of the inspection team. Based on the visual inspection, the present general condition of the dam is considered to be somewhat less than satisfactory. Several items were noticed during the inspection which are considered to have an adverse effect on the overall safety and future operation of the dam. These items include trees and areas of dense brush on the downstream face of the embankment, an excessively steep (as much as 1.0v on 1.5h) downstream slope, erosion of the grass covered upstream face of the dam, and a dense growth of cattails within the reservoir just upstream of the spillway. According to the criteria set forth in the recommended guidelines, the magnitude of the spillway design flood for the Gwenmil Lake Dam is specified, to be a minimum of the 100-year frequency flood and can be, depending upon the degree of risk involved, as much as one-half the Probable Maximum Flood (PMF). Considering the fact that a relatively small volume of water is impounded by the dam, that the flood plain downstream of the dam is fairly broad, that there are but three dwellings (two of which are well above the streambed) and a non-high hazard potential dam within the flood damage zone, it is recommended that the spillway for this dam be designed for the 100-year frequency flood.

Johnson and published by . This book was released on 1978 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam and lake are located on an unnamed tributary of La Barque Creek. The dam impounds water for the purpose of private recreation for surrounding residential property owners, who are members of the Lakewood Hills Property Owners Association. Major defects, including reconstruction of the upstream slope of the dam and sealing of the lake bottom, observed during this inspection are, according to the owner, planned to be corrected sometime this summer (1978) when a contract for remedial work on the dam and lake area is awarded. The remaining deficiencies observed during the inspection are not considered of major consequence to warrant immediate remedial action.

This book was released on 1981 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of a hydrologic/hydraulic analysis indicated that the spillway is adequate to pass lake outflow resulting from the 100-year frequency flood and the lake outflow corresponding to about 30 percent of the PMF lake inflow without overtopping the dam. According to the St. Louis District, Corps of Engineers, the length of the downstream flood damage zone, should failure of the dam occur, is estimated to be two miles. Accordingly, within the possible damage zone are four dwellings, Dam No. 30431, and two farm buildings. According to the Corps of Engineers, Dam No. 30431 has a significant hazard classification. A review of available data did not disclose that seepage or stability analysis of the dam were performed. This is considered a deficiency and should be rectified.

Krazynski and published by . This book was released on 1980 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Upper Valle Mines Dam is an abandoned tailings dam constructed to impound sand, silt and clay tailings produced by the milling of barite ore. The dam is reported to be primarily an earth embankment with a relatively thin mantle of gravel-size tailings (chat), and cobble- to boulder-size bullrock. Both the upstream and downstream faces of the dam are heavily vegetated with brush and trees up to 18 in. diameter. The reservoir is nearly filled with fine tailings. Much of the impoundment area is densely vegetated with brush and trees. The spillway is a broad trapezoidal notch cut at the left abutment. The notch is cut into the native soil and will likely be moderately erodible during periods of flood flow. The visual inspection and evaluation of available information indicate the dam is in generally poor condition. This judgment is based on the inability of the spillway to pass the 1 percent probability-of-occurrence (100 year) flood without overtopping the embankment, the hazard of erosion posed to the embankment in the event of overtopping, the dense vegetation on the embankment, as well as the steep slopes and evidence of limited past slumping on the downstream face of the dam.

Book excerpt: This dam has been classified as unsafe, non-emergency by the St. Louis District as a result of the application of the following criteria: the combined capacity of the spillways will not pass 50 percent of the Probable Maximum Flood without overtopping the dam; overtopping of the dam could result in failure of the dam; and dam failure significantly increases the hazard to loss of life downstream.
