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.

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.' The spillway will pass the 100-year flood without overtopping, which is a flood that has a 1 percent chance of being exceeded in any given year.

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.

Berggreen and published by . This book was released on 1981 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report assesses the general condition of the dam with aspect to safety, based on available data and on visual inspection, to determine if the dam poses hazards to human life or property. The St. Louis District (SLD), Corps of Engineers, has classified this dam as having a significant hazard potential. Based on the visual inspection and analysis of available data, the dam is judged to be in very poor condition. This assessment is based primarily on the history of the recent breach and seepage which developed at this dam, possibly along piping paths resulting from decaying root systems. The size of the trees on the embankment and the number of stumps where trees have been cut down indicate that similar seepage areas will likely continue to appear and pose a hazard of dam failure. Hydraulic/hydrologic analyses of the dam and appurtenant structures indicate the dam will be overtopped by a flood greater than 10 percent of the Probable Maximum Flood (PMF). The 1 percent probability-of-occurrence flood (occurs on the average once every 100 years) will overtop the dam by 0.7 ft. The relatively narrow embankment section and moderately erodible soil used in construction of the dam suggest overtopping would likely produce an effective breach of this dam. Seepage and stability analyses comparable to the requirements of the 'Recommended Guidelines for Safety Inspection of Dams' were not available. This is considered a deficiency which should be rectified.

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 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.

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 five families downstream of the dam and cause appreciable damage to Highway 25 bridge located approximately .6 mile downstream. 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 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 five families downstream of the dam, the PMF is considered the appropriate spillway design flood. The emergency spillway will only pass 40 percent of the PMF before the dam embankment is overtopped. Because the spillway will not pass one-half of the PMF without overtopping but will pass the 10-year frequency flood, the dam is classified as 'unsafe non-emergency'. The spillway will pass the 100-year flood without overtopping, which is a flood that has a 1 percent chance of being exceeded in any given year. There are no other hydrologic or hydraulic deficiencies.
