Phase I Inspection Report written by ARMY ENGINEER DISTRICT ST LOUIS MO. and published by . This book was released on 1978 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report assesses the general condition of the dam with respect to safety, based on available data and on visual inspection, to determine if the dam poses hazards to human life or property. Evaluation of the spillways' size indicates that they do not meet the criteria in the guidelines. The spillways of dams No. 2 and 3 are of inadequate size to pass the one percent chance flood (100-year flood) without overtopping. The spillway of dam No. 1 is just adequate to pass the one percent chance flood; but if either dam No. 2 or No. 3 failed due to overtopping, dam No. 1 would overtop also. The inspection team observed trees and bushes growing in the three dams inspected, particularly dam No. 3. These root systems are a potential seepage hazard. Localized areas of the embankment slopes are exceptionally steep. Steady seepage conditions exist through dam No. 1 and a localized seepage area was found downstream of dam No. 2. The pool of the dam No. 2 was on the downstream slope of dam No. 3 and seepage could not be evaluated. The three spillways do not appear sufficiently resistant to prevent embankment erosion at high flows for an indefinite time. Stilling basins are needed below each spillway. Seepage and stability analyses are not on record as recommended in the guidelines.

Lottes Dam (MO 30309) Lower Mississippi - St. Francis Basin, Wayne County, Missouri, Phase I Inspection Report written by ARMY ENGINEER DISTRICT ST LOUIS MO. and published by . This book was released on 1979 with total page 45 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 7 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. 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 approximately seven families downstream of the dam, the PMF is considered the appropriate spillway design. The emergency spillway will only pass 25 percent of the PMF before the dam embankment is overtopped. Because the spillway will not pass 1/2 of the PMF without overtopping but will pass the 10-year frequency flood, the dam is classified as 'unsafe non-emergency'. Other deficiencies visually observed by the inspection team were trees and trash blocking the emergency spillway, and deep erosion in the emergency spillway outfall; trees and bushes on the downstream embankment slope; erosion gullies on the downstream embankment slope; and seepage. Also, the trash rack and 13 inches of bituminous coated corrugated metal pipe were severed from the vertical inlet pipe.

Phase I Inspection Report written by ARMY ENGINEER DISTRICT ST LOUIS MO. and published by . 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.

Phase 1 Inspection Report written by and published by . This book was released on 1980 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this 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 combined spillways do not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The combined spillways will pass 25 percent of the Probable Maximum Flood without overtopping. 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 that are reasonably possible in the region. The guidelines require that a dam of small size with a high downstream hazard potential pass 50 to 100 percent of the PMF. Considering the low height of dam (26 ft) and the small storage capacity (64 acre-ft) 50 percent of the PMF has been determined to be the appropriate spillway design flood. The embankment was in good condition.

Phase I Inspection Report written by ARMY ENGINEER DISTRICT ST LOUIS MO. and published by . This book was released on 1980 with total page 61 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 an intermediate size dam with a high downstream hazard potential. Failure could threaten the life and property of approximately 5 families at Idlewild, MO and 10 families at Kinder, MO as well as endanger traffic and disrupt transportation on Highway 51 immediately south of the Refuge. The inspection and evaluation indicate that the discharge system is adequate to 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 discharge system is required to pass the Probable Maximum Flood (PMF) without the dam embankment being overtopped. The PMF 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 discharge structures for Duck Creek will not pass the PMF nor the one-half PMF without overtopping. The PMF and one-half PMF will overtop the northern portion of the levee, however, no downstream hazard should result from this overtopping since the overtopped levee is only about 1.5 ft. as shown by levee section 'L' on Plate 5.

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.

Jeffrey Kimball and published by . This book was released on 1980 with total page 51 pages. Available in PDF, EPUB and Kindle. 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.

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 approximately 3 families downstream of the dam and cause appreciable damage to highway FF, approximately 800 feet 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 38 percent of the PMF before the dam embankment is overtopped. Because the spillway will not pass 1/2 of the PMF without overtopping, the dam is classified as 'unsafe non-emergency.'

Download or read book National Dam Safety Program. Lawless Lake Dam (MO 31717), Mississippi - St. Francis Basin, Iron County, Missouri. Phase I Inspection Report written by Jean-Yves Perez and published by . 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).
