This book was released on 1981 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inspection and review of data of the Cokeburg Water Supply Dam revealed that further investigations of the magnitude of a Phase II are required. The inspection did not reveal any problems which require immediate emergency action. The dam appears to be in poor condition and poorly maintained. The structure is classified an unsafe, non-emergency. The stability of the structure is questionable due to the existence of coke ovens in the downstream slope of the embankment and failure of the discharge culvert outlet. Considerable erosion and/or settlement has occurred near the outlet of the spillway discharge culvert. The interior walls of the culvert, at the outlet are caving in and debris partially blocks the outlet. Portions of the reservoir slopes may contain coal refuse, which could lead to potential landslides affecting the storage and volume of the reservoir. During periods of heavy precipitation a potential landslide could occur, increasing the possibility for overtopping of the structure. The Cokeburg Water Supply 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 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 and property damage.

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 1979 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The PA-647 dam is one of the seven flood control structures in the Wheeling Creek watershed. The dam consists of an earth embankment approximately 500 feet long with a maximum height of 95 feet from the downstream toe and a crest width of 15 feet. The flood discharge facilities for the dam consist of a drop inlet type primary spillway located near the left abutment (looking downstream) and an emergency spillway on the right abutment. Based on the evaluation of the conditions as they existed on the dates of inspection and as revealed by visual observations, the condition of PA-647 dam is considered to be good. The spillway capacity is classified to be adequate according to the recommended criteria.

This book was released on 1980 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: The general condition of the Refuse Settling Basin is considered to be fair. This assessment is based on visual observations that indicate a possible inadequate margin of safety against slope failure of a high ground water level exists in Embankment A. The condition is not considered to represent an immediate threat to the structure because of the relatively low impoundment pool elevation. It should, however, be evaluated. If a high ground water does not exist in Embankment A, the facility can be considered to be in good condition. The structure is classified as an 'intermediate' size, 'high' hazard dam. Corps of Engineers guidelines recommend the Probable Maximum Flood (PMF) as the Spillway Design Flood for an 'intermediate' size, 'high' hazard dam. The visual inspection indicated several minor deficiencies in addition to the possible high ground water condition. The deficiencies can be corrected or improved through implementation of the following recommended evaluation, remedial, monitoring and/or maintenance efforts.

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.

Andersen and published by . This book was released on 1979 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cherry Valley Dam consists of an earth embankment approximately 475 feet long, with a maximum height of 33 feet from the downstream toe, and a crest width of 10 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 structures consist of an approach channel, a concrete overflow section, a spillway discharge channel, and stilling basin. The overflow structure of the spillway is a 130-foot-long concrete ogee section located at an elevation approximately 7.5 feet below the dam crest. The flow from the overflow section discharges into a trapezoidal concrete discharge channel which terminates at a plunge pool at the toe level of the dam near the right abutment. The outlet works consist of a concrete intake tower and two 24-inch cast-iron pipes through the embankment located at the center of the dam. The pipes are encased in concrete through the embankment and are equipped with concrete cutoff collars. The pipes receive flow from the wet intake tower and discharge into the outlet works discharge channel near the downstream toe of the dam. Flow through the pipes is controlled by gate valves located in a concrete valve chamber at the downstream end. This outlet system constitutes the emergency drawdown facility for the dam.

Mazzella and published by . This book was released on 1980 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Raw Water Pond was designed and constructed as an earthfill structure with clay core and cutoff along the centerline. The embankment is 1190 feet long, with a toe to crest height of 25.2 feet and a crest width of 25 feet. The Raw Water Pond outlet works is a 14 inch diameter steel pipe with an intake at the bottom of the Pond. The outlet works maintains the operating pool approximately 1.5 feet below the invert of the principal (and emergency) spillway. A gate valve and flow monitoring weir box are located downstream of the embankment. Outlet works flows are discharged to the Treated Water Pond below. Based on a review of available design information and visual observations of conditions as they existed on the date of the field inspection, the general condition of the Raw Water Pond is considered to be poor. This assessment is based primarily on visual observations that indicate a possible inadequate margin of safety against slope failure of the embankment. Spillway capacity is 'inadequate' because the non-overtopping flood discharge was found, by using the HEC-1 computer program, to be in 0.18 PMF.

This book was released on 1980 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edwards Dam consists of an earth embankment approximately 300 feet long with a maximum height of 30 feet from the downstream toe. The crest of the dam is irregular in the transverse direction with an average crest width of 8 feet. While the middle of the embankment is straight across the valley, short sections on each abutment side curve upstream. As designed, the embankment slopes are 2H to 1V on the upstream slope and 1.5H to 1V on the downstream slope. The flood discharge facilities for the reservoir consist of a 15-foot-wide, 4-foot-deep open channel located on the left abutment, equipped with an ogee overflow section. Flow from the overflow section discharges onto a 10-foot-long concrete apron which in turn discharges into an earth channel. The records indicate that the outlet facilities consist of a 12-inch cast-iron blow-off pipe and a 6-inch cast-iron supply line. Flow through the blow-off valve is controlled by a downstream valve located near the downstream toe of the embankment. The reservoir appears to be significantly silted. Therefore, the operational condition of the blow-off valve is questionable. This outlet system constitutes the emergency drawdown facility for the reservoir. (Author).
