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.

Shifrin and published by . This book was released on 1981 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sunrise Lake Dam was inspected. The overall condition of the dam appears to be fair; however, several deficiencies were noted by the inspection team. These deficiencies included: seepage under the spillway slab; cracks and spalling of the concrete in the spillway; the erosion of the banks of the discharge channel of the spillway; the erosion of the upstream slope due to wave action; several shallow surface sloughs observed on the embankment slopes; the presence of saplingss and brush on the embankment slopes and trees along the downstream, right abutment/embankment contact; a need for periodic maintenance of the grass cover; and a lack of a maintenance schedule. There exists a need for periodic inspection by a qualified engineer. The lack of seepage and stability analyses on record is also a deficiency that should be corrected.

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.

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.

This book was released on 1979 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, the present general condition of the dam is considered to be satisfactory. The following deficiencies were noticed during the inspection and are considered to have an adverse effect on the overall safety and future operation of the dam. A minor collection of floating debris is lodged within the drop inlet spillway structure at the upstream end of the outlet pipe. An accumulation of debris within the spillway structure can obstruct the outlet pipe resulting in a loss of discharge capacity and unwarranted flooding of the lake. Several beaver dams exist within the downstream channel between the dam and the juncture of the channel with Cliffdale Hollow, a distance of about 1,000 feet. Damming of the channel is believed to be responsible for the tailwater pool that lies adjacent to the downstream toe of the dam. In addition, the outfall channel that lies between the outfall structure and the downstream channel is partially obstructed by small trees and brush.

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.
