This book was released on 1980 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lakeside Dam is privately owned, and the reservoir is used for recreational purposes. The dam and spillway structures are currently in poor condition. In accordance with criteria established by Federal (OCE) Guidelines, the recommended spillway design flood for this 'Small' size dam and 'Significant' hazard classification is the 100 Year Flood to one-half the Probable Maximum Flood (PMF). Based on the damage center located 2,000 feet downstream of the dam, the one-half PMF event has been selected as the spillway design flood. Hydrologic and hydraulic computations presented in Appendix D indicate that the spillway structure is capable of discharging less than 0.1 PMF without overtopping the embankment. As the structure will not discharge the spillway design flood without overtopping the embankment, it is considered to have an 'Inadequate' spillway. (Author).

This book was released on 1980 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kunkles Dam is a privately owned dam used for recreational purposes. The dam and spillway structures of Kunkles Dam are currently in poor condition. In accordance with criteria established by Federal (OCE) Guidelines, the recommended spillway design flood for this 'Small' size dam and 'Significant' hazard potential classification is the 100 Year Flood to one-half the Probable Maximum Flood (PMF). Based on the small capacity of the reservoir and the fact that no loss of life is likely during failure of the structure, the 100 Year Event has been selected as the spillway design flood. Hydrologic and hydraulic computations presented in Appendix D indicate that the spillway structure is not capable of discharging the 100 Year Event without overtopping the embankment by about 0.8 foot for about 3.5 hours. The structure is considered to have an 'Inadequate' spillway as it will not pass the spillway deisgn flood without overtopping the embankment. (Author).

This book was released on 1978 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, available records, calculations and past operational performance, Silver Creek Dam is judged to be in fair condition. The spillway and the low overbanks adjacent to the spillway have sufficient capacity to the Probable Maximum Flood (PMF) without overtopping the dam. Based on criteria established for these studies by the Department of the Army, Office of the Chief of Engineers (OCE), the spillway capacity is rated as adequate. The existing spillway and the adjacent overbanks can accommodate a flood with a peak inflow of 115 percent of the PMF peak flow. (Author).

This book was released on 1979 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Swiftwater Dam is a 31 + or - foot high zoned embankment containing an impervious core founded in hardpan. The embankment has upstream and downstream slopes of 2.5H:1V and a crest width of 10 feet. When the old spillway was relocated to the right abutment, the embankment section was reconstructed and is a homogeneous embankment with an eight foot wide cutoff trench founded on impervious materials. The upstream and downstream slopes were both constructed at 2.5H:1V with a 10 foot crest width. The upstream slope of the whole embankment is protected with riprap, minimum thickness being 18 inches on the new embankment and 12 inches on the old embankment. The embankment impounds a 21-acre reservoir. The embankment also contains a gatehouse tower located near the crest of the dam approximately midway along the length of the embankment. The gatehouse tower contains a steel sluice gate manufactured by the Caldwell-Wilcox Company. Documentation in the files indicates that the intake pipe is 42 inches in diameter, located at the base of the embankment, and encased in concrete with anti-seep collars.

This book was released on 1978 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, available records, calculations and past operational performance, Crystal Dam is judged to be in good condition. However, the spillway will not pass the Probable Maximum Flood (PMF) or one-half of the PMF without overtopping. If Crystal Dam should fail due to overtopping, the hazard to loss of life downstream from the dam would be significantly increased from that which would exist just prior to overtopping. Based on criteria established for these studies by the Department of the Army, Office of the Chief of Engineers (OCE), the spillway capacity is rated as seriously inadequate. The existing spillway can accommodate a flood with a peak inflow of 37 percent of the PMF peak flow. If the low areas of the top of the embankment were brought up to design grade, the spillway could accommodate a flood with a peak inflow of 61 percent of the PMF peak inflow. The spillway would then be rated as inadequate instead of seriously inadequate.

This book was released on 1979 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sunrise Lake Dam is a homogeneous earthfill embankment 478 feet long and 27 feet high at its maximum section. The embankment has a curved alignment. A concrete chute spillway is located near the right abutment of the top of the. The approach channel is the reservoir area. The ogee crest is 105 feet long and 7.25 feet lower than the design elevation of the dam. Based on visual inspection, available records, calculations, past operational performance, and according to criteria established for these studies, Sunrise Lake Dam is judged to be in good condition. The spillway capacity is rated as adequate. The spillway can pass the Probable Maximum Flood (PMF) without overtopping of the dam. The headwall at the conduit outlet is tilted and is considered to be unsatisfactory. In the absence of stability computations showing that an adequate factor of safety exists, the downstream slope is considered to have a marginal factor of safety because of the steepness of the slope.

This book was released on 1980 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Lower Dam is based upon visual observations made at the time of inspection, review of available records and data, hydraulic and hydrologic computations and past operational performance. Lower Dam is a high hazard-intermediate size dam. The spillway design flood (SDF) is the PMF (Probable Maximum Flood). The exisitng spillway and reservoir are capable of controlling approximately 15% of the PMF. Based on criteria established by the Corps of Engineers, the spillway is termed inadequate. If Lower Dam should fail due to overtopping, the hazard to loss of life and property downstream from the dam would not be significantly increased from that would exist just prior to overtopping. Extensive seepage is exiting through or beneath the dam. In addition, the embankment or foundation materials may be piping due to the excessive seepage. The dam appears to be in poor condition. As a result, the dam is considered an unsafe, nonemergency dam. (Author).

This book was released on 1979 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greenwood Dam is an earthfill embankment, originally constructed in 1880. The embankment height was increased in 1901 or 1904 and again in 1935 to its present configuration. The length of the embankment is about 850 feet with a maximum height of 32 feet. Four 20-inch pipes are placed under the embankment with valves at the downstream end without control at the upstream end. The pipes are supported on a masonry wall. The outlets of these pipes are not visible because they are submerged under the backwater of the Lake Hauto Dam, which is located immediately downstream. The spillway is located in the left abutment, about 100 feet from the end of the dam. The spillway is a concrete ogee weir and the discharge channel is cut out of the rock. The length of the ogee section is 94.5 feet and the weir crest is 2.0 feet above the approach channel. The left side of the spillway is sloped and cement paved. The right side is a vertical wall of stone, laid in mortar.
