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 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chambers Dam appears to be in poor condition and poorly maintained. Erosion of the upstream slope has reduced the embankment crest to a width of 4 feet. Minor seepage was observed on the downstream slope of the dam, and a wet area was observed immediately beyond the toe of the dam. Brush and trees litter the downstream slope of the dam. No determination could be made as to the actual condition of the drainline culvert through the embankment. No determination could be made as to the condition or type of upstream closure on the culvert or whether the control is operable. The spillway located at the right abutment of the dam is in a deteriorating condition. Erosion exists along the right outside edge of the spillway wingwall. If the erosion is left unchecked, the potential for failure of the spillway and dam exists. The Chambers Dam is a high hazard-small size dam. The recommended Spillway Design Flood (SDF) for a dam of this size and classification is in the range of 1/2 PMF to PMF. Based on the downstream potential for loss of life and property damage, the spillway design flood has been selected as the PMF. The spillway and reservoir are capable of controlling less than 1% of the PMF without overtopping the embankment low spot.

This book was released on 1981 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a review of available information, visual observations of conditions as they existed on the date of the field inspection, and supporting engineering calculations, the general condition of the Montour No. 4 Refuse Bank is considered to be fair. This assessment is based primarily on visual observations of the embankment. The structure is classified as a large size, significant hazard dam. Corps of Engineers guidelines recommend the Probable Maximum Flood (PMF) as the Spillway Design Flood for a large size significant hazard dam. Montour No. 4 Refuse Bank's Spillway Design Flood is the Probable Maximum Flood. Reservoir capacity is 'adequate' because the non-overtopping flood inflow was found, by using the HEC-1 computer program, to be in excess of 100 percent of the PMF.

This book was released on 1981 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the investigation is to make a determination on whether or not the dam constitutes a hazard to human life or property. Mine No. 60-Pond 5 is located at the headwaters of an unnamed tributary to the Center Branch of Pigeon Creek, in Somerset Township, Washington, County, Pennsylvania. The Mine No. 60-Pond 5 is classified as a 'high' hazard dam. The No. Mine 60-Pond 5 is owned by the Bethlehem Mines Corporation Eight-Four, Pennsylvania. The field inspection of Mine No. 60-Pond 5 was performed on 18 March 1981 and 26 March 1981 and consisted of: Visual observations of the embankment crest and slopes, groins and abutments; Visual observations of the principal (and emergency) spillway including approach channel, overflow crest, and discharge channel; Visual observations of the embankment's downstream toe area including drainage channels and surficial conditions; Visual observations of downstream conditions and evaluation of the downstream hazard potential; Visual observations of the reservoir shoreline and watershed; Visual observations of the outlet works; Transit stadia surveys of relative elevations along the embankment crest centerline, spillway, and across the embankment slopes. The visual observations were made during periods when the reservoir was at normal operating level.

Dziubek and published by . This book was released on 1980 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neal Dam, owned and operated by Vernon C. Neal, is classified as a 'Small' size - 'significant' hazard dam. The dam was found to be in good overall condition at the time of inspection. Hydraulic/hydrologic evaluations, performed in accordance with procedures established by the Baltimore District, Corps of Engineers, for Phase I Inspection Reports, revealed that the spillway will pass the 100-year flood without overtopping the dam. A spillway design flood (SDF) in the range of the 100-year flood to the 1/2 Probable Maximum Flood (1/2 PMF) is required for Neal Dam. The 100-year flood was chosen because the dam is on the low side of the 'Small' size category. The spillway is therefore considered 'adequate.' Several minor items of remedial work should be performed by the owner as soon as practicable.

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.
