Shifrin and published by . This book was released on 1979 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. Within the estimated five mile damage zone downstream of the dam are seven houses, six buildings, and one road crossing which may be subjected to flooding, with possible damage and/or destruction, and possible loss of life. B & K Lake No. 1 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. B & K Lake No. 1 Dam being a small size dam with a high hazard potential, is required by the guidelines to pass from one-half of the Probable Maximum Flood to the Probable Maximum Flood without overtopping. Since there is high hazard potential downstream of the dam, the appropriate spillway design flood for this dam is the Probable Maximum Flood. It was determined that the reservoir/spillway system can accommodate 17 percent of the Probable Maximum Flood without overtopping the dam. Our evaluation also indicates that the reservoir/spillway system can accommodate the 100-year flood without overtopping the dam.

Book excerpt: White, Smith, Austin Lake Dam is located in Warren County, Missouri at the headwaters of Schlanker Branch. The purpose of the dam is to impound water for recreational use as a private lake. The lake is utilized by landowners adjacent to the lake. The crest of the embankment has a thick grass cover. Trees and large brush currently densely vegetate the downstream slope of the embankment. One small area on the downstream embankment slope near the center of the dam has recently been cleared of trees and brush. The upstream slope has brush and small trees growing on the right side of the embankment, while the vegetation on the left side has recently been cut.

Book excerpt: Woodridge Lake Dam is situated on a small intermittant stream about 1000 feet upstream of its confluence with the intermittant Dry Fork. The main purpose of the dam is to impound water for recreational use for landowners adjacent to the dam. The following problems were observed which could affect the safety of the dam or which will require maintenance within a reasonable period of time. Deep erosion gulley along the downstream left abutment contact, and erosion gullies at the right abutment contact; Wave erosion on the upstream embankment slope; Poorly channelized exit for the emergency spillway discharges which causes ponded water at downstream toe and erosion along the left abutment contact; and Undercutting on the discharge end of the service spillway pipe, and the ponded water found downstream of this pipe.

This book was released on 1981 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spring Lake Dam is an earthfill structure approximately 21 feet high and 400 feet long at the crest. The appurtenant works consist of a drop-inlet pipe principal spillway and a trapezoidal channel cut into natural ground at the left abutment which acts as an emergency spillway. Our inspection and evaluation indicates that the spillway has not met the criteria set forth in the guidelines for a small size dam in the high hazard potential category. This structure has the capability to hold and pass approximately 40 percent of the Probable Maximum Flood (PMF) before overtopping. The dam appeared to be in fair condition. Deficiencies visually observed by the inspection team were: (1) a row of trees (approximately 8) along the upstream face of the dam; (2) a significant potential for restriction to flow into the principal spillway intake; (3) some minor erosion on the downstream face of the dam; (4) the emergency spillway channel is partially obstructed by six steel drums and a fence; and (5) minor seepage into the principal spillway conduit from within the embankment.

Book excerpt: This dam has been classified as unsafe, non-emergency by the St. Louis District as a result of the application of the following criteria: the combined capacity of the spillways will not pass 50 percent of the Probable Maximum Flood without overtopping the dam; overtopping of the dam could result in failure of the dam; and dam failure significantly increases the hazard to loss of life downstream.

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.
