Book excerpt: Fredricktown City Dam is located 1.5 miles northwest of Fredericktown, Missouri on the Little St. Francis River. Fredericktown City Dam is used for water supply. The visual inspection did not reveal any immediate signs of instability. The inspection revealed the concrete was in good condition. The stream basin and downstream face below the tailwater were unobserved because of the water level. In addition, any undercutting of the toe was not determined.

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.

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.

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.

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.

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.
