This book was released on 1978 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Henry Sever Dam No. Mo. 10110 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. Two farmhouses with associated farm buildings, five trailer camping pads, one improved road crossing, one state highway, and the town of Newark, Missouri would be subjected to flooding, with possible damage and/or destruction, and possible loss of life. Henry Sever Dam is in the intermediate size classification since it is more than 40 feet high, but less than 100 feet high, and impounds more than 1,000 acre-feet, but less than 50,000 acre-feet of water. Our inspection and evaluation indicates that the spillway of Henry Sever Dam does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential.

Shifrin and published by . This book was released on 1979 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dams (the main dam and the check dam) are in significant hazard potential classification. Significant hazard potential category structures will be those located in predominantly rural or agricultural areas where failure may damage isolated homes, secondary highways or minor railroads or cause interruption of use or service of relatively important public utilities. The main dam is classified as small in the dam size category because its height is less than 40 feet, and it impounds less than 1,000 acre-feet of water. The check dam, which is three feet in height, forms a continuous barrier to the impoundment created by the main dam. The spillway of C & A Lake Dam does not meet the criteria set forth in the guidelines for dams having the above size and hazard potential. C & A Lake Dam being a small size dam with a significant hazard potential, is required by the guidelines to pass from 100-year to one-half of the Probable Maximum Flood without overtopping. Since there is significant hazard potential downstream of the dam and because of its location just upstream of a highway, the appropriate spillway design flood for C & A Lake Dam is one-half of the Probable Maximum Flood.

Shifrin and published by . This book was released on 1979 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lancaster City Dam is located near the headwaters of the North Fork of the Middle Fabius River. The main purpose of the dam is to impound water for recreational use and a supplemental water supply. The crest of the dam is protected against surface erosion by a cover of grass and clover. There was no evidence of significant settlement or cracking on the crest. No deviations in horizontal or vertical alignment were apparent. Some evidence of rodent activity was observed on the embankment. There was no evidence of the dam ever being overtopped. The upstream slope was protected by concrete rubble riprap to one foot above the water surface. Considerable erosion due to wave action above the riprap indicates the riprap might have been placed after construction of the dam. Scarps ranging from 1 to 3 feet high have been cut into the upper part of the upstream face. Several bushes and small trees were growing on the upper grass covered slope. No bulges or depressions in the slope were observed.

This book was released on 1978 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dam has been classified by the St. Louis District Corps of Engineers as an intermediate size dam with a high downstream hazard potential. Their estimate of the potential damage zone extends 6 miles downstream of the dam. The 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 15 percent of the Probable Maximum Flood (PMF) without overtopping. The spillway will not pass the 100-year frequency flood without overtopping (15 percent of the PMF is smaller than the 100-year flood). The embankment and appurtenances inspected appear to be in good condition. However, the unlined spillway presents a potentially dangerous situation that should be corrected.

Shifrin and published by . This book was released on 1980 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is a zoned, rolled, earthfill structure with a straight alignment between rock abutments. The top of dam width is 45 feet and the axis length of the crest of the embankment was measured as 856 feet. The maximum height of the dam was measured as 38 feet above creekbed elevation. The spillway serves as both an emergency spillway for larger flows and a principal spillway for the normal flows. The spillway crest and adjacent channel area were blasted out of rock just to the right of the right abutment. A low level drain consists of two 22 inch diameter welded steel pipes which pass through the embankment side by side. Each pipe is controlled at the downstream end by a 24 inch gate valve. The dam appears to be in satisfactory condition. However, several deficiencies were noted by the inspection team that could affect the safety of the dam. Our inspection and evaluation indicates that the spillway of Incline Village Lake Dam can accommodate approximately 60 percent of the Probable Maximum Flood without overtopping the dam. Our evaluation also indicates that the reservoir/spillway system can accommodate the one-percent chance flood without overtopping.

Shifrin and published by . This book was released on 1980 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ehrlich Lake Dam is located in Montgomery County, Missouri, on an unnamed tributary to Coon Creek. The dam was constructed to impound water for crop irrigation. The top of the dam which serves as an access road for farm equipment does not have adequate erosion protection. Some minor damage due to the vehicular traffic was observed. A small depression was observed on the crest at the point where the principal spillway pipe passes through the embankment which appears to be due to settlement of backfill placed in the pipe excavation. No other settlements of the crest or cracks were observed. No significant deviation in the vertical or horizontal alignment was apparent, other than the curved alignment as originally constructed. According to Mr. Ehrlich, the dam has never been overtopped and no evidence indicating the contrary was observed.
