This book was released on 1979 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Rene Dam consists of an earth embankment approximately 900 feet long with a maximum height of 82 feet from the downstream toe and a crest width of 60 feet. Lake Rene Dam is one of three dams which impound Lake Rene. The other two dams are Wolf Creek Dam, located at the west end of the reservoir, and Galion Bay Dam, located on the south side of the reservoir. Lake Rene Dam, which was constructed in 1955, was the original dam at the site. The original dam impounded a reservoir with a surface area of approximately 240 acres at normal pool elevation (Elevation 1658). The Wolf Creek and Galion Bay dams were constructed in 1971, increasing the surface area of the reservoir to approximately 310 acres at normal pool level of Elevation 1662.5. Based on the evaluation of the existing conditions, the condition of Lake Rene Dam is assessed to be unsafe due to numerous seeps and slumps on the downstream face of the dam and due to lack of operable outlet works for the reservoir. However, it is not an emergency condition.

Anderson and published by . This book was released on 1979 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The New Dam consists of an earth embankment approximately 330 feet long with a maximum height of 37 feet from the downstream toe and a crest width of 32 to 35 feet. The flood discharge facilities for the dam consist of a combined primary and emergency spillway located on the right abutment (looking downstream). The spillway is an earth channel excavated into the right abutment and includes neither an overflow control structure, nor an energy dissipation structure at the downstream end. The width of the channel varies from 30 feet at the upstream end to 20 feet at the downstream end. The channel follows the right abutment for approximately 200 feet, then turns left, and discharges freely over the hillside into the stream valley. The outlet works consist of a 24-inch cast-iron blowoff pipe and a concrete intake tower. The concrete intake tower is located on the upstream side of the dam approximately mid-height of the embankment. All the operating equipment on the intake tower has seriously deteriorated and is no longer functional. The blow-off pipe appears to extend 50 to 100 feet further upstream from the intake tower. No low-level intake structure was visible. Flow through the outlet conduit is controlled by a valve located at the downstream end. The valve was reportedly left open to draw down the lake.

This book was released on 1981 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Brown's Lake Dam is based upon visual observations made at the time of inspection, hydraulic and hydrologic computations and past operational performance. The inspection and review of data of the Brown's Lake Dam did not reveal any problems which would require emergency action. The dam appears to be in good condition and adequately maintained. Brown's Lake Dam is a high hazard-small size dam. The spillway design flood (SDF) for a dam of this size and classification is 1/2 PMF to the PMF. the PMF has been selected as the spillway design flood based on downstream potential for loss of life. The spillway and reservoir are capable of controlling the spillway design flood (PMF). Based on criteria established by the Corps of Engineers, the spillway is termed adequate. The following recommendations and remedial measures should be instituted as soon as possible. (1) A regularly scheduled maintenance program should be developed and implemented. (2) A warning system should be developed to warn downstream residents of large spillway discharges or imminent failure of the dam. (3) A safety inspection program should be implemented with inspections at regular intervals by qualified personnel. (4) The drainline valve should be operated on a regular basis.

Dziubek and published by . This book was released on 1980 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: PA 480 was designed by the U.S. Department of Agriculture, Soil Conservation Service (SCS) for floodwater detention. The total length of the dam is 555 feet, including the emergency spillway on the right abutement; the maximum height of the dam is 66 feet. The principal spillway is a drop-inlet structure consisting of a two-stage reinforced concrete riser connected to a 30 inch diameter reinforced concrete outlet pipe. The low-level inlet on the concrete riser is a 9 inch high by 15 inch wide orifice; this inlet maintains the normal pool level. There is 25.1 acre-feet of storage at normal pool level, all of which is reserved for a 50-year accumulation of sediment. Hydraulic/hydrologic evaluations, revealed that the spillway will pass the Probable Maximum Flood (PMF) without overtopping the dam. A spillway design flood (SDF) in the range of the 1/2 Probable Maximum Flood (1/2 PMF) to the PMF is required for PA 480. The 1/2 PMF was selected as the SDF. The spillway is therefore considered to be 'adequate'.

This book was released on 1981 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual inspection and review of available design and construction information indicate that Lake Quinn Dam is in fair condition. Deficiencies noted during the inspection included the lack of functional drawdown facilities and minor seepage through the masonry near the right abutment. Based on the size and hazard classification of the dam, the recommended Spillway Design Flood (SDF) varies between 1/2 the Probable Maximum Flood (PMF) and the PMF. The 1/2 PMF has been selected as the SDF due to the size of the dam and reservoir, and the downstream conditions. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and spillway discharge capacity will pass only 3 percent of the PMF without overtopping the dam. Overtopping the dam could cause failure, which would lead to a significant increase in downstream loss of life and property damage. Therefore, the spillway for Lake Quinn Dam is considered to be seriously inadequate, and the dam is judged to be unsafe, non-emergency.

Jeffrey Kimball and published by . This book was released on 1981 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inspection and review of data of the Clear Lake Dam did not reveal any problems which require emergency action. The dam appeared to be in poor condition and poorly maintained. The Clear Lake Dam is a high hazard-small size dam. The spillway design flood (SDF) for a dam of this size and classification is in the range of the 1/2 PMF to the PMF. The PMF has been selected as the spillway design flood based on the downstream potential for loss of life. The spillway and reservoir are capable of controlling approximately 6% of the PMF. Based on criteria established by the Corps of Engineers, the spillway is termed seriously inadequate. Clear Lake Dam is classified as an unsafe non-emergency dam. A detailed stability and seepage analysis should be conducted by a registered professional engineer knowledgeable in dam design and construction and should be conducted in conjunction with a hydrologic and hydraulic analysis of the structure to increase spillway capacity and the stability of the structure. The method used to block the penstock should be investigated by a registered professional engineer knowledgeable in dam design and construction. Repairs should be conducted accordingly.

Anderson and published by . This book was released on 1979 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Pine Creek Dam consists of an earth embankment approximately 1130 feet long with a maximum height of about 33 feet. As built, the crest of the dam was 60 feet wide with a 2 horizontal to 1 vertical sslope on both the upstream and downstream faces. Over the years, significant fill has been placed on the downstream side of the embankment, increasing the crest width to 300 to 400 feet. A two-lane roadway crosses the crest of the dam. Near the left abutment (looking downstream) the side slope of the spillway discharge channel defines the toe of the present embankment. However, for the remaining major portion of the embankment, no discernible demarcation exists between the embankment and the natural ground that can be identified as the toe of the embankment. Fill placed on the downstream side of theembankment gradually merges to the right abutment. The flood discharge facilities for the dam consist of a combined primary and emergency spillway located near the left abutment. The spillway structures include an ogee overflow section, circular arc in plane view, which discharges into a rectangular concrete discharge channel. A single-span highway bridge crosses the spillway discharge channel, approximately 70 feet downstream from the crest of the overflow section. The crest of theogee overflow section of the spillway is located at an elevation approximately 10 feet below the low point on the crest of the dam.
