King and published by . This book was released on 1979 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of Dresser No. 4 Dam is to impound tailings from a barite separation and beneficiation operation. The dam completely encircles the impoundment except for a 300-foot wide breach at the north (up-stream) end where the structure failed in 1975. The dam cannot retain water in its present state because of this breach in the dam. This dam is classified as large. The U.S. Corps of Engineers has classified it as having a high downstream hazard potential to indicate that failure of this dam could threaten life and property. The damage zone, estimated by the U.S. Corps of Engineers, extends about 6 miles downstream of the dam. Since the embankment cannot retain water, the overtopping potential of the embankment was not analyzed. Instead, studies were made to estimate the amount of flow that could occur in the diversion ditch (located to the west and south of the impoundment) under different flood conditions. It was calculated that the diversion ditch could pass a 100-year flood probably without significant erosion of the ditch or adjacent embankment toe. However, it was estimated that the ditch cannot pass 50 percent of the Probable Maximum Flood without significant erosion of the ditch and adjacent embankment materials.

King and published by . This book was released on 1979 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of No Name 587 Dam is to impound tailings from a barite separation and beneficiation operation. The dam completely encircles the impoundment. Runoff from the watershed is diverted around the impoundment via diversion ditches. This dam is classified as intermediate size. The U.S. Corps of Engineers has classified this dam as having high downstream hazard potential to indicate that failure of this dam could threaten life and property. The damage zone estimated by the U.S. Corps of Engineers extends approximately eight miles downstream of the dam. Information provided by the Corps of Engineers and the inspection indicates that about five dwellings, two railroad bridges, a highway bridge and the town of Mineral Point with about eighty dwellings are within this damage zone. The results of the inspection indicate the absence of facilities for discharging floodwater and inadequate freeboard and that the dam does not meet the criteria given in the Guidelines for a structure with the size and hazard potential of No Name 587 Dam. As an intermediate size dam with a high hazard potential, the Guidelines specify that the discharge capacity and/or storage capacity should be capable of safely handling the Probable Maximum Flood (PMF) without overtopping the crest.

King and published by . This book was released on 1979 with total page 76 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 is based upon an evaluation of the available data, a visual inspection, and an evaluation of the hydrology and hydraulics of the site in order to determine if the dam poses hazards to human life or property. The dam provides impoundment for barite ore tailings. The results of the inspection and evaluation indicated that the spillway does not meet the criteria given in the guidelines for a dam with the size and hazard potential of Bottom Diggins Dam. As an intermediate size dam with a high hazard potential, the Guidelines specify that the discharge capacity and/or storage capacity should be capable of safely handling the Probable Maximum Flood (PMF) without overtopping the crest. The PMF is the flood that may be expected from the most severe combination of critical meteorological and hydrologic conditions that are reasonably possible in the region.

Gizienski and published by . This book was released on 1980 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Place Dam, Missouri Inventory No. 30996, was inspected. Based on these guidelines, the St Louis District, Corps of Engineers (SLD), has determined that this dam has a high hazard potential; we concur with this classification. The damage zone length, as determined by the St Louis District, Corps of Engineers, extends approximately two miles downstream. Within the damage zone are several occupied dwellings. The dam is classified as small due to its 180 ac-ft storage volume. The dam height is approximately 16 ft. The small dam classification includes dams having a storage volume between 50 and 1000 ac-ft, or a height between 25 and 40 ft. Our inspection and evaluation indicate the dam is in generally poor condition. The major deficiencies noted were inadequate spillway capacity, the heavy growth of trees and bushes on the dam, the presence of animal burrows and lack of maintenance and periodic inspections. Seepage and stability analyses comparable to the requirements of the 'Recommended Guidelines for Safety Inspection of Dams' were not available, which is considered a deficiency.

Book excerpt: The Big Four Mine Dam (Mononame 562), Missouri Inventory Number 30729 was inspected. This dam is classified as intermediate due to its 71 ft height and live storage of 1980 ac-ft. The St Louis District, Corps of Engineers, has classified this dam as a high hazard dam; we concur with this classification. The potential damage zone, extends approximately 22 mi downstream. The community of Fletcher and several other occupied structures are located within the estimated damage zone. The inspection and evaluation indicate that the dam is in poor condition. Specific deficiencies that were noted are very steep downstream slope, high potential for erosion of downstream toe by spillway outflow, high erodibility of the embankment materials and lack of maintenance and periodic inspections. Also deemed as a deficiency is the lack of any stability or seepage analyses.

Book excerpt: The purpose of the inspection was to assess the general condition of the dam with respect to safety. The assessment is based upon an evaluation of the available data, a visual inspection, and an evaluation of the hydrology and hydraulics of the site in order to determine if the dam poses hazards to human life or property. The dam provides impoundment for barite ore tailings. The impoundment is inactive, but tailings disposal activities may resume in the near future. The results of the inspection and evaluation indicate that the spillways do not meet the criteria given in the guidelines for a dam with the size and hazard potential of Old Washer No. 1 Dam. As an intermediate size dam with a high hazard potential, the Guidelines specify that the discharge capacity and/or storage capacity should be capable of safely handling the Probable Maximum Flood (PMF) without overtopping the crest. The PMF is the flood that may be expected from the most severe combination of critical meteorologic and hydrologic conditions that are reasonably possible in the region.

Book excerpt: This report presents the results of field inspection and evaluation of the Black Tailings Dam. This dam has been classified as unsafe, emergency by the St. Louis District as a result of the application of the following criteria: (1) This dam which has no spillway will not contain a 10-year frequency flood without overtopping occurring. The storage capacity of this dam is, therefore, considered to be unusually small and seriously inadequate; (2) Overtopping could result in dam failure; and (3) Dam failure would significantly increase the hazard to life and property downstream.

Book excerpt: The Pierce Lake Dam, Missouri Inventory Number 30999, was inspected. This dam is classified as small due to its 37 ft height and storage capacity of 681 ac-ft. A small dam is one which is less than 40 ft in height and impounds less than 1000 ac-ft of storage. The St. Louis District, Corps of Engineers, has classified this dam high hazard; we concur with this classification. The estimated damage zone, as determined by the St. Louis District, Corps of Engineers, extends approximately five miles downstream. The community of Richwoods and several other occupied structures are located within the estimated damage zone. The inspection and evaluation indicate that the dam is in generally poor condition. Specific deficiencies that were noted are insufficient spillway capacity, very steep downstream slope, high erodibility of the embankment materials and lack of maintenance and periodic inspections. Also deemed as a deficiency is the lack of any stability or seepage analyses.
