Decker and published by . This book was released on 1980 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the inspection was to make an assessment of the general conditions 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 spillways do not meet the criteria set forth in the recommended guidelines for a small dam having a high hazard potential. Considering the small volume of water impounded and the downstream channel from the dam, one-half of the Probable Maximum Flood is the appropriate spillway design flood. The spillways will pass the 100-year flood (1% probability flood - a flood having a one percent chance of being exceeded in any one year) without overtopping the dam. The spillways will pass 13% of the Probable Maximum Flood without overtopping the dam. The Probable Maximum Flood (PMF) is defined as the flood that may be expected from the most severe combination of critical meteorologic and hydrologic conditions that are reasonably possible in the region.

Shifrin and published by . This book was released on 1979 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lynch Lake Dam was inspected. Based on the criteria in the guidelines, the dam is in the high hazard potential classification, which means that loss of life and appreciable property loss could occur in the event of failure of the dam. The estimated damage zone extends approximately three miles downstream of the dam. Within the first two miles of the damage zone are nine dwellings, Highway NN and bridge which may be subjected to flooding, with possible damage and/or destruction, and possible loss of life. Lynch Lake Dam is in the small size classification since it is less than 40 feet high and impounds less than 1,000 acre-feet of water.

Phase I Inspection Report written by Steve Brady and published by . This book was released on 1979 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Serene Dam is an earthfill structure approximately 37 ft high and 1200 ft long at the crest. The appurtenant works consist of a rock cut spillway with a concrete weir control structure located at the south abutment, and a 12-in. diameter siphon pipe located near the north end of the dam. Our inspection and evaluation indicates that the spillway does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The spillway will pass 27 percent of the Probable Maximum Flood without overtopping. Deficiencies visually observed by the inspection team were: (1) erosion at the contacts of the dam with the north and south abutments; (2) tree and brush growth on downstream face of dam; (3) animal burrows on face of dam; (4) concrete debris on dam face near spillway; and (5) debris in spillway outlet channel.

Phase I Inspection Report written by Steve Brady and published by . This book was released on 1979 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthonis Dam is an earthfill structure approximately 39 ft high and 420 ft long at the crest. The only spillway associated with the dam is an unlined earth swale (uncontrolled crest) around the north abutment. Our inspection and evaluation indicates that the spillway does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. the spillway will pass 44 percent of the Probable Maximum Flood without overtopping. Deficiencies visually observed by the inspection team were: (1) heavy brush and tree growth on embankment surface; (2) erosion at the south abutment - dam contact and on the downstream face; (3) small animal burrows in the embankment; (4) weed and cattail growth in the spillway approach channel; (5) wet areas at and beyond downstream toe of embankment; (6) lack of wave protection for upstream face of embankment; and (7) lack of a non-erodible control section for the spillway.

Phase I Inspection Report written by Dave Daniels and published by . This book was released on 1980 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Von Der Ahe Dam is an earthfill structure approximately 37 ft. high and 660 ft. long at the crest. The appurtenant works consist of an 18-inch diameter concrete pipe at east abutment, a 24-inch diameter steel primary spillway pipe at Sta. 4 + 82 and a 9-inch diameter steel drawdown pipe at Sta. 4 + 95. Our 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 33 percent of the Probable Maximum Flood without overtopping. The embankment appeared to be generally in good condition. Deficiencies visually observed by the inspection team were: (1) Erosion of downstream face at toe of embankment; (2) Erosion of upstream face of dam at elevation of primary spillway inlet; (3) Lack of trash rack on the primary spillway inlet; and (4) Apparent seepage through bedrock in the east abutment; and (5) Seepage through drain pipe valve.

Phase I Inspection Report written by Harold B. Lockett and published by . This book was released on 1980 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection and the results of the hydrologic/hydraulic investigations, the present general condition of the dam is considered to be less than satisfactory. Deficiencies were noticed during the inspection and are considered to have an adverse effect on the overall safety and future operation of the dam. Seepage, as characterized by cattails, willow trees, soft ground, and standing water was observed in two areas adjacent to the toe of the downstream slope of the dam. Uncontrolled seepage could develop into a piping condition (progressive internal erosion) that can lead to failure of the dam. Erosion of the grass covered upstream face of the dam apparently by wave action and/or fluctuations of the lake surface level has created a near vertical bank approximately 12-to-18 inches high. A grass covered slope is not considered adequate protection to prevent erosion of the embankment by wave action or fluctuations of the lake level. Loss of material by erosion can be detrimental to the dam's stability. At the time of the inspection, the grass and other turf cover on the dam slopes was about 3 feet high. Some areas of the dam were also covered with undergrowth including small tress and dense brush. The vegetative cover should not be allowed to reach a height that provides cover for burrowing animals or hinders inspection of the dam.

Phase I Inspection Report written by Albert B Becker (Jr) and published by . This book was released on 1978 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, certain deficiencies were noted during the inspection and are considered to have an adverse effect on the overall safety and future operation of the dam and spillway. At the time of the inspection, the grass growing on the crest, and the upstream and downstream faces of the dam was on the order of 24 inches high. The grass should not be allowed to grow to a height that provides cover for burrowing animals or hinders inspection of the dam. Several areas of dense brush that may conceal animal burrows and trees exist on the crest and upstream and downstream faces of the dam. Several holes that appear to be animal burrows were observed in the upstream face, downstream face, and crest of the dam. The upstream face of the dam is grass covered throughout. A considerable amount of erosion of the upstream slope of the dam at the waterline has occurred. The concrete retaining wall located on the downstream side of th dam near the left abutment that serves to support the embankment at this location is cracked in several locations. The concrete slope paving located on the right bank of the principal spillway outlet channel at a point approximately 100 feet downstream of the spillway crest is undercut and the pavement subgrade and embankment extensively eroded.

Phase I Inspection Report written by ARMY ENGINEER DISTRICT ST LOUIS MO. and published by . This book was released on 1978 with total page 28 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. The inspection team concluded that the dam is unsafe. Based on the criteria in the guidelines, the dam is in the high hazard potential classification, which means that loss of life or appreciable property loss could occur in the event of failure of the dam. A subdivided recreational development with several dozen numbered lots is located adjacent to the creek within a mile below the dam. These lots are apparently in frequent use for camping. Several downstream residences would also be subject to possible damage. The dam is in the intermediate size classification since it is more than 40 feet high. A major earth slide was present on the downstream face. Excessive seepage was occurring through and beneath the dam and its abutments. The spillway in the right abutment is inadequate to pass any flow without overtopping, because the invert of the spillway is higher than the top of the dam.

Phase I Inspection Report written by Steve Brady and published by . This book was released on 1979 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this inspection of the Las Brisas Lake Dam 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 guidelines used in the assessment indicate that this dam is in the high hazard potential classification. The dam is in the intermediate size classification, since it is greater than 40 ft high but less than 100 ft high. The inspection and evaluation indicate 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 58 percent of the Probable Maximum Flood without overtopping. The guidelines require that a dam of intermediate size with a high downstream hazard potential pass the PMF. The 100-year frequency flood will not overtop the dam. The 100-year flood is one that has a 1 percent chance of being exceeded in any given year.

Berggreen and published by . This book was released on 1981 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: The St Louis District (SLD), Corps of Engineers, has classified this dam as having a high hazard potential. The dam is classified intermediate size based on its height of about 45 to 50 feet. The downstream face is steep, on the order of 33 to 35 degrees, is constructed of cohesionless sand gravel, and could be severely eroded if overtopped. Scattered large trees up to 12 in. diameter are growing on the downstream face of the dam. The reservoir storage volume is completely filled with fine tailings and storage of water is limited to two small ponds at the upstream end of the impoundment, and shallow, intermittent ponds on the surface of the tailings. Hydraulic/hydrologic analyses indicate the dam and informal spillway will pass the 1 percent probability-of-occurrence event (100-year flood) without overtopping the embankment. These analyses further indicate the dam will be overtopped by a storm which produces greater than 55 percent of the Probable Maximum Flood (PMF). Based on the inspection of the Dam, it is recommended that further study be conducted without undue delay, under the guidance of an engineer experienced in the design and construction of tailings dams.
