Phase I Inspection Report written by John A. Dziubek and published by . This book was released on 1980 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polk Dam is owned by the Polk State School and Hospital and is classified as a 'Significant' hazard - 'Small' size dam. The dam was found to be in fair 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 not 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 Polk Dam. The 100-year flood was chosen as the SDF. During the 100-year flood, the dam is overtopped by a maximum of 0.61 foot for a duration of 1.50 hours. The spillway is therefore considered 'inadequate.' It is recommended that the owner immediately initiate an engineering study to further evaluate the spillway capacity and develop recommendations for remedial measures to reduce the overtopping potential of the dam. Several items of remedial work should be performed by the owner without delay.

Phase I Inspection Report written by Chuan Yuan Chen and published by . This book was released on 1979 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Boydstown Dam is a diaphragm earthfill embankment approximately 28 feet high (maximum) and 330 feet long. The spillway is located at the left abutment of the dam. It is uncontrolled, and the broad-crested weir is 60 feet long (perpendicular to flow). An analysis indicated that the spillway will pass only 30 percent of the required Probable Maximum Flood before overtopping will occur. As a result of this analysis and others, the spillway is considered 'seriously inadequate.' The overall condition of the dam was assessed to be very poor because the upper half of the spillway is in such a deteriorated condition that significant damage to the structure may occur if large flows were to pass through the spillway. In addition, several features of the dam do not meet current design standards; the 7 foot crest width, the lack of an internal drainage system, the absence of positive cut-offs along the outlet and water supply pipes, and the lack of information concerning the details and condition of the outlet works.

Phase I Inspection Report written by GAI CONSULTANTS INC MONROEVILLE PA. and published by . This book was released on 1979 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beaver Dam is an earth embankment approximately 32 feet high and 385 feet long (including spillway). The dam is constructed with a masonry spillway located about 35 feet left of the right abutment. The crest of the spillway is 100 feet long and about 11 feet below the top of its wingwalls. Based on a visual inspection, operational history, and available engineering data, the dam is consisered to be in poor condition. The defunct facility has been essentially abandoned since 1952 and its reservoir is sediment filled. Results of the hydrologic and hydraulic analysis indicate that the facility is capable of passing and/or storing only 36 percent of the PMF without embankment overtopping. Structural deficiencies noted by the inspection team included substantial embankment overgrowth, an access road cut through the embankment near the left abutment, cracking of the masonry spillway wingwalls, and a sediment filled reservoir. Due to the seriously inadequate spillway and overall poor condition, the facility is considered unsafe but non-emergency as failure is not considered imminent.

Phase I Inspection Report written by and published by . This book was released on 1981 with total page 78 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 Russellton Slurry Pond 3 is considered to be fair. This assessment is based primarily on visual observations of the embankment, spillway and seepage conditions and hydrology/ hydraulic analyses of reservoir/spillway capacity. The structure is classified as a 'large' size, 'high' hazard structure. Corps of Engineers guidelines recommend the Probable Maximum Flood (PMF) as the Spillway Design Flood for a 'large' size, 'high' hazard dam. Pond 3'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 Phase I investigation of Pond 3 revealed deficiencies and conditions which should be corrected or improved through implementation of the following recommended remedial, monitoring and/or improvement efforts.

Dziubek and published by . This book was released on 1980 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kenda Dam is owned and operated by the Westmoreland Recreation Society, Inc. and is classified as a Small size - High hazard dam. The dam was found to be in poor 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 not pass the 1/2 Probable Maximum Flood (1/2 PMF) without overtopping the dam. A spillway design flood (SDF) in the range of the 1/2 PMF to Probable Maximum Flood (PMF) is required for Kenda Dam. The 1/2 PMF was selected as the SDF because of the small size of the drainage area and impoundment. During the 1/2 PMF, the dam is overtopped by a maximum depth of 1.24 feet for a total duration of 7.00 hours. It is estimated that, in its present condition, the dam is likely to fail during the 1/2 PMF. Analysis performed to assess the impact of failure of the dam on the damage center downstream indicated that a significant increase in damage would occur compared to conditions if the dam did not fail. Therefore, the spillway is assessed as being seriously inadequate. It is recommended that the owner immediately initiate an engineering study to further evaluate the spillway capacity and develop recommendations for remedial measures to reduce the overtopping potential of the dam.

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: Ligonier Dam (Ligonier Township Reservoir) is classified as a 'High' hazard - 'Small' size dam. The dam and reservoir, owned by the Ligonier Township Municipal Water Authority, are used for water supply. 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 approximately 35 percent of the Probable Maximum Flood (PMF) before overtopping will occur. A spillway design flood (SDF) in the range of the 1/2 Probable Maximum Flood (1/2 PMF) to the PMF is required for Ligonier Dam. Because of the relative small size of the impoundment the 1/2 PMF was chosen as the SDF. It was determined that during the 1/2 PMF the low area on the embankment would be overtopped by a depth of 0.66 foot and a duration of 4.50 hours. Because a limiting criteria of one foot or greater depth of overtopping and a duration of 2 hours was estimated for this dam, it was concluded that a dam failure during the 1/2 PMF is unlikely to occur.

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.

Phase I Inspection Report written by BAKER (MICHAEL) JR INC BEAVER PA. and published by . This book was released on 1979 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Little Shenango Dam (PA 490) is a homogeneous earth floodwater retarding dam designed by the U.S. Department of Agriculture, Soil Conservation Service. The dam has a crest length of 430 feet, a maximum height of 45 feet, a storage volume of 472 acre-feet at spillway crest level, and a storage volume of 19 acre-feet at normal pool level. The dam was found to be in generally poor condition at the time of inspection. The inspection did disclose potential problems with seepage and piping in the dam embankment and abutments. A detailed engineering investigation of seepage, piping, erosion, and structural stability of the dam should be initiated as expeditiously as possible. Hydraulic/hydrologic evaluations revealed that the spillway will pass the Probable Maximum Flood (PMF) without overtopping the dam. The spillway is therefore considered 'adequate'.
