This book was released on 1978 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is in the high hazard potential classification, which means that loss of life and appreciable property loss could occur in the event of failure of the dam. The downstream damage zone is approximately 3 miles long. Over 10 existing homes plus more than 10 additional planned home sites are located within one mile downstream of the dam. These homes and four improved road crossings would be subjected to flooding with possible damage and/or destruction and possible loss of life if the dam should suddenly fail. The dam is in the small size classification because it is less than 40 feet high and impounds less than 1000 acre-feet of water. For its size and hazard category, this dam is required by the guidelines to pass one-half PMF to the PMF. However, considering the high hazard potential to life (10 existing homes and 10 planned homes) and property downstream of the dam, the PMF is considered the appropriate spillway design flood. The PMF is defined as resulting from the most severe combination of critical meteorologic and hydrologic conditions that are reasonably possible in the region.

Berggreen and published by . This book was released on 1980 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lower Valle Mines Dam is classified as small, based on its storage capacity of 78 ac-ft. The dam is 22 ft in height. The small dam classification applies to dams between 25 and 40 ft high, or those with storage volume between 50 and 1000 ac-ft. The St. Louis District, Corps of Engineers, has classified this dam as having a high hazard potential; we concur with this classification. The estimated damage zone length extends approximately two miles downstream of the dam. Within this estimated damage zone are two improved roads, the dam and reservoir at Lake Valle, and numerous vacation and permanent dwellings on the shores of the lake. The potential for loss of life and property may be high in the event of a dam failure. Lower Valle Mines Dam is an earth dam, densely vegetated with brush and trees. There are two spillways, the main spillway on the left or west abutment and the auxiliary spillway on the east abutment. The visual inspection and evaluation of available data indicate Lower Valle Mines Dam is in generally fair condition. This judgment is based on the potential for overtopping, and the dense vegetation on the downstream face of the embankment. The embankment materials appear moderately erodible, both the vegetation presently offers some erosion protection. Seepage in the area beyond the toe of the dam does not appear to pose a hazard to the dam at this time. The lack of periodic inspections and maintenance on the dam is considered a deficiency.

Reitz and published by . This book was released on 1978 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Williams 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 five families and cause appreciable damage to one railroad bridge and one highway crossing. Our inspection and evaluation indicates that the dam is deficient in that the spillways do not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. Considering the small volume of water impounded, the large floodplain downstream and the five buildings downstream, one-half 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 that are reasonably possible in the region. The dam will begin to be overtopped by a flood having a discharge (peak and volume) equal to 15% of the PMF. The spillways 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.

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.
