This book was released on 1978 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the inspection was to assess the general condition of the dam with respect to safety and, based upon this inspection and available data, determine if the dam poses a hazard to human life or property. The following 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: A dense cover of small- to medium-size trees and brush that may conceal animal burrows exists on the upstream face of the dam. The upstream face of the dam is in an unkept state. The crest width of the dam is non-uniform and varies from approximately 60 feet to more than 100 feet. The course of the spillway outlet channel is not readily discernible due to the existence of dense brush and trees that begin at the end of the spillway control section. This dam, which is classified as intermediate in size and of high hazard potential, is specified to be the Probable Maximum Flood (PMF). Results of a hydrologic/hydraulic analysis indicated that the existing spillway is inadequate to pass the lake outflow resulting from a storm of PMF magnitude without overtopping the dam. The length of the downstream damage zone, should failure of the dam occur, is estimated to be six miles.

This book was released on 1978 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the inspection was to assess the general condition of the dam with respect to safety and, based upon this inspection and available data, determine if the dam poses a hazard to human life or property. Based on the criteria set forth in the recommended guidelines, and since numerous homes and a summer camping facility lie within the estimated flood zones, recommended spillway design flood for this dam, which is classified as small in size and of high hazard potential, is Probable Maximum Flood (PMF). PMF is the flood that may be expected from the most severe combination of critical meteorologic and hydrologic conditions that are reasonably possible in the region. Results of a hydrologic/hydraulic analysis indicated that the existing spillways (principal and emergency) are inadequate to pass the lake outflow resulting from a storm of PMF magnitude without overtopping the dam. A similar analysis also indicated that the spillways are inadequate to pass the lake outflow resulting from the 1 percent chance (100-year frequency) flood without overtopping the dam. The spillways are capable of passing lake outflow corresponding to approximately 13 percent of the PMF without overtopping the dam. The length of the downstream damage zone, should failure of the dam occur, is estimated to be six miles.

Berggreen and published by . This book was released on 1981 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: The St Louis District (SLD), Corps of Engineers, has classified this dam as having a high hazard potential. The dam is classified intermediate size based on its height of about 45 to 50 feet. The downstream face is steep, on the order of 33 to 35 degrees, is constructed of cohesionless sand gravel, and could be severely eroded if overtopped. Scattered large trees up to 12 in. diameter are growing on the downstream face of the dam. The reservoir storage volume is completely filled with fine tailings and storage of water is limited to two small ponds at the upstream end of the impoundment, and shallow, intermittent ponds on the surface of the tailings. Hydraulic/hydrologic analyses indicate the dam and informal spillway will pass the 1 percent probability-of-occurrence event (100-year flood) without overtopping the embankment. These analyses further indicate the dam will be overtopped by a storm which produces greater than 55 percent of the Probable Maximum Flood (PMF). Based on the inspection of the Dam, it is recommended that further study be conducted without undue delay, under the guidance of an engineer experienced in the design and construction of tailings dams.

King and published by . This book was released on 1979 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the inspection was to assess the general condition of the dam with respect to safety. The assessment is based upon an evaluation of the available data, a visual inspection, and an evaluation of the hydrology and hydraulics of the site in order to determine if the dam poses hazards to human life or property. The dam provides impoundment for barite ore tailings. The impoundment is inactive, but tailings disposal activities may resume in the near future. The results of the inspection and evaluation indicate that the spillways do not meet the criteria given in the guidelines for a dam with the size and hazard potential of Old Washer No. 1 Dam. As an intermediate size dam with a high hazard potential, the Guidelines specify that the discharge capacity and/or storage capacity should be capable of safely handling the Probable Maximum Flood (PMF) without overtopping the crest. The PMF is the flood that may be expected from the most severe combination of critical meteorologic and hydrologic conditions that are reasonably possible in the region.
