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.

Berggreen and published by . This book was released on 1980 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gudaitis Lake Dam is in the small size classification based on its maximum height of 25 ft and on its reservoir storage volume of about 180 ac-ft. The small dam classification includes dams between 25 and 40 ft in height or having storage capacities between 50 and 1000 ac-ft. The inspection and evaluation indicate the dam is in fair condition. This evaluation is primarily based on hydrologic analyses that indicate that a flood greater than 12 percent of the PMF will effectively overtop the dam. The dam will also be effectively overtopped by the one percent probability-of-occurrence (100 year) flood event. A 40 ft wide zone of slow seepage was noted at the toe of the dam, but the seepage water was not transporting any soil particles at the time of our inspection. The downstream face of the dam is heavily vegetated with relatively young trees up to 12 in. in diameter. This vegetation obscured portions of the dam from inspection. The spillway discharge channel is narrow and shallow and is bordered by many large trees. Deep gulley erosion is occurring where this channel traverses steeper slopes. Flood flows in this channel could cause overtopping of the channel and erosion of the channel walls, resulting in possible erosion at the toe of the dam.

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.

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.
