This book was released on 1980 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: John Bollinger No. 1 Dam is an earth dam constructed to impound a lake for irrigation. The normal operating pool outlet or main spillway consists of a 12-in. diameter asbestos-concrete pipe through the center of the dam. The outlet of this pipe is near the toe of the maximum section. A crude trash rack has been constructed around the inlet end. An auxiliary spillway is located at the right abutment. There are no control structures for regulating flows through this auxiliary spillway. Our inspection and evaluation indicate the dam is in generally good condition. No evidence of significant erosion, sliding, cracking or excessive settlement was noted on this dam. No animal burrows were noted. Hydraulic/hydrologic analyses indicate the 1 percent probability-of-occurrence event (100 year flood) will be passed without overtopping the dam. These analyses also indicate any storm greater than 45 percent of the PMF will overtop the embankment.

Book excerpt: Mine LaMotte Dam is located approximately 1 mile northeast of Mine LaMotte, Missouri, on an unnamed tributary to the St. Francois River. Mine LaMotte Dam is used for recreation. The visual inspection revealed that the earth embankment is in poor condition. Both the upstream and downstream slope are very steep. The upstream slope has recently had additional material end dumped on the slope and thus shows signs of instability. The downstream slope is covered with a thick growth of trees. Seepage is exiting from one portion of the downstream slope near the reservoir water level. In addition, seepage and ponded water is present at the toe of the higher portions of the dam.

King and published by . This book was released on 1979 with total page 114 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 was based on an evaluation of the available data, a visual inspection and an evaluation of the hydrology and hydraulics of the site to determine if the dam poses hazards to human life or property. The purpose of the dam is to impound lead tailings. Inspection and evaluation indicated that the combined capacity of the spillway and 48-inch diameter concrete outlet does not meet the criteria given in the Guidelines for a dam of the size and hazard potential of Main Tailings Dam. As a small dam with a high hazard potential, it is required by the Guidelines to pass to 50 100 percent of the Probable Maximum Flood (PMF) without overtopping the crest. The spillway design flood adopted for this dam is 100 percent of the PMF because the consequences of failure are serious since the dam is located about 1/4-mile from a residential area of Fredericktown. The PMF is the flood that maybe expected from the most severe combination of critical meteorologic and hydrologic conditions that is reasonably possible in the region. It was calculated that the spillway and outlet could pass a 100-year flood (a flood having a 1 percent change of being equalled or exceeded in any 1 year) without overtopping the dam.

This book was released on 1978 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dam is classified as a small size dam with a high downstream hazard potential. Failure would threaten the life and property of approximately 5 families downstream of the dam. The spillway does not meet the criteria set forth in the guidelines for a dam having the above mentioned size classification and hazard potential. According to the guidelines, the spillway is required to pass the Probable Maximum Flood (PMF) without the dam embankment being overtopped. The spillway will only pass 5 percent of the PMF before the dam embankment is overtopped. Because the spillway will not pass one-half of the PMF without overtopping, the dam is classified as 'unsafe Non-emergency'. The spillway will not pass the 100-year flood without overtopping, which is a flood that has a 1 percent chance of being exceeded in any given year. Other deficiencies visually observed by the inspection team were trees and bushes next to the concrete core wall, in and adjacent to the principal spillway, and on the downstream embankment slope; erosion gullies on the downstream embankment slope; and seepage. Another deficiency found was the lack of seepage and stability analysis records.

Berggreen and published by . This book was released on 1981 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wright Lake Dam, Missouri Inventory No. 31062, was inspected. The dam is an earth dam constructed for recreational purposes. The St Louis District (SLD), Corps of Engineers has classified this dam as having a high hazard potential; we concur with this classification. The hazard zone length estimated by the SLD extends approximately two and one-half miles downstream of the dam. Within this zone are Reed Lake Dam (MO 30859) and more than six occupied dwellings. Due to the small distance to the nearest downstream residences and Reed Lake Dam and the potential for damage due to outflow during overtopping, it is recommended that 100 percent of the Probable Maximum Flood (PMF) should be used as the spillway design flood. The PMF is defined as the flood evvent that may be expected to occur from the most severe combination of critical meteorological and hydrologic conditions that are reasonably possible in the region.

This book was released on 1981 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is an earth dam, constructed of weathered rock and soil from the vicinity of the dam, impounding a lake for recreational purposes. When the reservoir was first filled, the owner noticed a loss of water and drained the lake to perform repairs. The reservoir was still nearly empty at the time of the visual inspection. The spillways are at the left abutment of the dam (as the observer faces downstream). The main spillway is a 24-in. diameter corrugated steel pipe passing through the embankment near the left abutment. The auxiliary spillway is an uncontrolled, unlined, irregularly-shaped open channel in the left abutment. Our inspection and evaluation indicate the embankment is in generally good condition. No evidence was found of significant erosion, slope instability, disruption of the vertical or horizontal alignment of the dam, or detrimental vegetation. Hydrologic/hydraulic analyses indicate that a 1 percent probability-of-occurrence event (100-year flood) will not result in overtopping of the dam. These analyses also indicate that the dam will be overtopped by a flood event which produces greater than 14 percent of the Probable Maximum Flood (PMF).

This book was released on 1981 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Slime Pond Dam is an earth dam constructed in the 1950's to impound tailings and water from a lead ore processing mill. It consists of a long, curved earth embankment, convex downstream, spanning a wide, relatively flat drainage basin. The crest of the dam is approximately 2430 ft long. There is no spillway. The lake level is controlled by a concrete intake tower which was part of the decant system. The overflow from the intake tower flows through a conduit installed through the embankment, exiting at the downstream toe of the dam through a concrete pump house. Our visual inspection and evaluation of available information indicate the dam is in generally poor condition. No evidence was noted of cracking, slumping, sinkhole development, animal burrows, or disruption of the vertical or horizontal alignment of the dam crest. However, the downstream slope of the embankment is steep, on the order of 1.4(H) to 1(V) and may be subject to slumping. Large trees, to 12-in. in diameter are growing on the downstream slope and could provide piping paths or voids in the embankment if they are cut, die or are blown down. Hydraulic/hydrologic analyses indicate the dam will be overtopped by a flood which produces greater than 40 percent of the Probable Maximum Flood.

This book was released on 1979 with total page 43 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. This dam is classified as a small size dam with a high downstream hazard potential. Failure would threaten the life and property of 2 or more families downstream of the dam. The inspection and evaluation indicate that the spillway does not meet the criteria set forth in the guidelines for a dam having the above mentioned size and classification and hazard potential. For its size and hazard category, this dam is required by the guidelines to pass from one-half PMF to PMF. However, considering the high-hazard potential to life and property of two families downstream of the dam, the PMF is considered the appropriate spillway design flood. Other deficiencies visually observed by the inspection team were trees, bushes, and seepage on the downstream embankment slow and toe; erosion gullies and sloughing on the downstream embankment slope; minor wavewash on the upstream embankment slope; and undermining of the downstream ends of the primary and emergency discharge structures.
