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.

Available in PDF, EPUB and Kindle. Book excerpt: The Lake Bono Del Dam, which according to the St. Louis District, Corps of Engineers, is of high hazard potential, was visually inspected by engineering personnel. The purpose of this 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 an inordinate danger to human life or property. The following report 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 and the results of these hydrologic/hydraulic investigations, the present general condition of the dam is considered to be somewhat less than satisfactory. Several deficiencies were observed during the visual inspection which are considered to have an adverse effect on the overall safety and future operation of the dam. These deficiencies include such items as trees and brush on the downstream face of the dam, animal burrows in the upstream face of the dam, embankment erosion at the upstream face of the dam, and a fence extending across the spillway channel.

Reitz and published by . This book was released on 1978 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. The 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 volume of water impounded, the small floodplain downstream and the 25 buildings downstream, the 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 reasonably possible in the region. The dam will begin to be overtopped by a flood having a discharge (peak and volume) equal to 45% of the PMF. The spillways will pass 1% chance flood (100-year flood) without overtopping which is a flood that has a 1% chance of being exceeded in any given year. Other deficiencies noted by the inspection team were underseepage or seepage at the base of the dam embankment and heavy growth of trees and shrubs on the downstream slope of the dam.
