This book was released on 1980 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sample Run Dam consists of an earth embankment approximately 325 feet long with a maximum height of approximately 23 feet from the downstream toe. The crest width is approximately 10 feet. As designed, the downstream face of the dam was to be protected by grass, and a vertical concrete wall on the upstream side was to provide shoreline protection. Presently, the downstream face of the dam is covered with brush and trees up to 10 feet high and the concrete wall on the upstream side has partially collapsed. The spillway structures are comprised of an 18-foot-wide concrete ogee overflow section which discharges into an 18-foot-long concrete channel, incorporating an energy dissipator sill. Based on the evaluation of the existing conditions, the condition of Sample Run Dam is considered to be poor. The dam is abandoned and is in complete disrepair. A valve house located at the downstream toe of the dam has collapsed, covering most of the operating equipment with rubble. The flood discharge capacity of the dam was evaluated according to the recommended procedure and was found to pass 20 percent of the probable maximum flood (PMF).

Washington County, Pennsylvania. Phase I Inspection Report written by John A. 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'.

Phase I Inspection Report written by D'APPOLONIA CONSULTING ENGINEERS INC PITTSBURGH PA. and published by . This book was released on 1980 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Graceton Dam consists of an earth embankment approximately 250 feet long with a maximum height of approximately 26 feet from the downstream toe. The crest width is approximately 10 feet. A 10-foot-wide berm is located on the downstream slope at about midheight of the embankment. The downstream slope of the embankment is approximately 1.5H to 1V above the berm and 2.5H to 1V below that level. The flood discharge facilities for the reservoir consist of a concrete overflow structure located on the left abutment (looking downstream). The overflow section is approximately 15 feet wide and 3 feet deep and discharges onto an approximately 30-foot-long concrete chute. According to the previous inspection reports, the outlet facilities consist of two cast-iron pipes 4 and 6 inches in diameter. the location of the pipes and the manner in which flow through these pipes is controlled is unknown. In the design drawings, flow through these pipes is shown to be controlled by valves located in a valve chamber on the downstream side of the dam. However, this valve chamber could not be located at the site during this inspection. As it presently exists, the dam has no functional emergency drawdown facilities. (Author).

Phase I Inspection Report written by Lawrence D. Andersen and published by . This book was released on 1980 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions, the condition of Elroy Face Dam is considered to be unsafe/nonemergency. A portion of the embankment crest adjacent to the overflow spillway located on the left abutment was found to be about 3 feet below the design crest level and only 8 inches above normal pool level. Relative to this low spot, the capacity of the spillway is estimated to be 66 cfs (approximately 5 percent of the probable maximum flood), which is significantly less than the lower limit of the recommended spillway design flood of the 100-year flood for the dam, based on its size and hazard classification. Therefore, the spillway capacity is considered to be inadequate. A preliminary survey of the crest of the dam indicated that the remaining portion of the crest is also below the design level by about one to two feet. The crest and the downstream face of the dam were found to be covered with thick brush and trees, essentially precluding proper inspection of the embankment. The embankment was generally found to be in poor condition with extensive swampy areas along the downstream toe and shoreline erosion on the upstream side. The spillway structures and the downstream end of the outlet pipe were found to be structurally in poor condition and requiring repairs.

Phase I Inspection Report written by Lawrence D. 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.

Mihalcin and published by . This book was released on 1980 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and available engineering data, the dam is considered to be in good condition. The size classification of the facility is small and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Due to the high potential for damage to downstream structures and loss of life, the SDF for the facility is considered to be the PMF. Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store a flood of PMF magnitude. Consequently, the spillway is considered adequate.
