Inspection Report written by James P. Hannan 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 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 Fairchance Reservoir Dam is considered to be fair. This classification id based on: (1) The visual observation of the seeps in the pond drain discharge channel; (2) The presence of growing and fallen trees on the embankment slope; (3) Outlet works pipes through the embankment that have no positive upstream flow controls; and (4) An inadequate spillway capacity. The structure is classified as a small size, high hazard dam for which the Corps of Engineers guidelines require a Spillway Design Flood (SDF). For the observed downstream conditions the Fairchance Reservoir Dam SDF is one half the Probable Maximum Flood (PMF). Spillway capacity is inadequate because the non-over-topping flood discharge capacity, as estimated using the HEC-1 computer program was found to be 4 percent of the PMF. The spillway is not seriously inadequate because failure of the structure would not significantly increase the flood stage and risk of loss life downstream.

Download or read book National Dam Inspection Program. Star Junction Number 2 Dam. (NDI Number PA-00212 PennDER Number 26-31) Ohio River Basin. Fayette County, Commonwealth of Pennsylvania. Phase I Inspection Report written by James P. Hannan and published by . This book was released on 1980 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Star Junction No. 2 Dam consists of an earthfill embankment and masonry spillway on the left abutment. The dam has a crest length of 341 feet, a maximum height of 30 feet and a storage volume of 31 acre-feet at the spillway crest level. The dam is classified by Corps of Engineers guidelines to be a small size, high hazard structure. Star Junction No. 2 Dam's embankment is assessed to be in poor condition. This is based on visual observations of the non-uniform slope, wet zones and state inspection reports. The downstream control was observed to be damaged and probably is not operable. No control or mechanism was observed to permit upstream flow control. The principal spillway is assessed to be in very poor condition. This is based on visual observations of the weir wall and training dike retaining wall. Both structures are partially collapsed and badly deteriorated and safe performance is questionable in the event of long-term, high discharge conditions.

Number 26-101), Ohio River Basin, Little Sandy Creek, Fayette County, Pennsylvania. Phase I Inspection Report written by and published by . This book was released on 1981 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and available engineering data, Heritage Reservation Dam is considered to be in excellent condition. The size classification of the facility is intermediate and the hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) is considered to be the PMF (Probable Maximum Flood). Results of the hydrologic and hydraulic analysis indicate that the facility is capable of passing and/or storing the PMF without overtopping the dam or dike. Consequently, the spillway is considered adequate.

Phase I Inspection Report written by James P. Hannan and published by . This book was released on 1980 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a review of available design information, engineering analyses, and visual observations of conditions as they existed on the date of the field inspection, the general condition of the Colonial Dam No. 1 is considered to be fair. This assessment is based on visual observations and hydrologic calculations that indicated: (1) that the earth embankment is in good condition, (2) that the principal spillways are in poor physical condition and have 'inadequate' capacity but are not 'seriously inadequate', and (3) the existence of non-serious deficiencies which are considered correctable. The structure is classified as a 'small' size, 'high' hazard dam. Corps of Engineers guidelines recommend 1/2 to one times the Probable Maximum Flood (PMF) for 'small' size, 'high' hazard dam. Colonial No. 1 Dam's Spillway Design Flood is 1/2 the Probable Maximum Flood (PMF).

Phase I Inspection Report written by William McCormick and published by . This book was released on 1980 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Star Junction No. 1 dam consists of an earthfill embankment and masonry spillway on the right abutment. The dam has a crest length of 545 feet, a maximum height of 35 feet and a storage volume of 149.3 acre-feet at the spillway crest level. The dam is classified by Corps of Engineers guidelines to be a small size, high hazard structure. Based on the visual observations and the data available, the dam is categorized as being in an unsafe, non-emergency condition. The visual inspection revealed that the masonry spillway on the right abutment has deteriorated to the extent that its structural integrity during extended, large discharge conditions, is questionable.

Phase I Inspection Report written by Bernard M. Mihalcin and published by . This book was released on 1979 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Base on a visual inspection, operational history, and available engineering data, the dam is considered to be in fair 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 is the Probable Maximum Flood (PMF). Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store about 62 percent of the PMF prior to embankment overtopping. Consequently, the spillway is assessed as being inadequate, but not seriously inadequate. Deficiencies noted by the inspection team included heavy overgrowth across the downstream toe, a questionable structural and foundation design associated with the spillway, and an inadequate emergency warning system.

Phase I Inspection Report written by GAI CONSULTANTS INC MONROEVILLE PA. and published by . This book was released on 1979 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hutchinson Reservoir Dam Number 1 is an earth embankment (with an upstream concrete face) approximately 308 feet in length and with a maximum height of 33 feet. The embankment reportedly is provided with a 2-foot thick clay puddle core wall extending 14 feet below the original ground surface. The facility is served by a rectangular concrete overflow spillway with a multiple vertical drop concrete discharge channel along the right abutment. A 20-inch diameter cast-iron pipe passing through the embankment serves as a supply line. Reservoir drawdown control is provided by a 14-inch diameter cast-iron blowoff conduit which parallels the 20-inch supply line. The blowoff conduit is valved on the upstream side within a concrete intake tower (referred to as a vault by the owner's personnel). At the upstream end of the reservoir is a sedimentation basin and miscellaneous appurtenances which can direct flow (via flash boards) into Reservoir Number 1 and/or into an earth and masonry raceway which can carry part of the inflow around the reservoir.

Montour Number 4 Refuse Bank (NDI Number PA 00865, PENN DER Number 63-92), Ohio River Basin, Tributary to Chartiers Creek, Washington County, Pennsylvania. Phase I Inspection Report written by and published by . 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.

United States Steel Corporation, Raw Materials Division. Phase I Inspection Report written by ACKENHEIL AND ASSOCIATES INC PITTSBURGH PA. and published by . This book was released on 1981 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Silt Pond A is considered to be good. This assessment is based primarily on visual observations of the embankment and appurtenances, and hydrologic/hydraulic analyses of reservoir/spillway capacity. The structure is classified as a 'small' size, 'high' hazard dam. Corps of Engineers guidelines recommend one-half to one times the Probable Maximum Flood (PMF) as the Spillway Design Flood for a 'small' size, 'high' hazard dam. Silt Pond A's Spillway Design Flood is the Probable Maximum Flood. Spillway capacity is 'adequate' because the non-overtopping flood discharge was found, by using the HEC-1 computer program, to be in excess of 100 percent of the PMF. The field inspection indicated three minor deficiencies which can be corrected or improved through implementation of the following recommended evaluation, remedial and/or maintenance efforts.
