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 Lawrence D. Anderson and published by . This book was released on 1979 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions on March 14 and April 16, 1979, the condition of Little Blue Run Dam is considered to be good. No conditions were noted at this time that would significantly affect the structural performance of the dam. The flood discharge facilities for the dam were designed to pass the probable maximum flood (PMF) without overtopping the embankment. Therefore, according to the recommended criteria, the flood discharge facilities of the dam are adequate. Presently, the pool elevation is approximately 170 feet below the dam crest level. The pool elevation is expected to reach spillway crest level in about the year 2010. The following recommendations should be implemented on a continuing basis: (1) The cracking observed on the crest should continue to be evaluated by the design engineers. Also, attention should be given to the slump and seepage observed on the left abutment. Erosion ditches on the right abutment should be filled; and (2) A formal warning system should be developed to alert the downstream residents in the event of emergencies.

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'.

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.

Beaver Pond Dam (NDI Number PA-00133, PennDER Number 64-19), Susquehanna River Basin, Unnamed Tributary of Shadigee Creek, Wayne County, Pennsylvania. Phase I Inspection Report written by BAKER (MICHAEL) JR INC BEAVER PA. and published by . This book was released on 1981 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beaver Pond Dam is classified as a 'Significant' hazard - 'Small' size 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 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 Beaver Pond Dam. Because the dam is on the low end of the 'Small' size category in terms of storage capacity and height, the 100-year flood was chosen as the SDF. During the 100-year flood, the dam is overtopping by a maximum depth of 3.27 feet for a total duration of 8.67 hours. The spillway is therefore considered 'Inadequate.' It is recommended that the owner immediately develop recommendations for remedial measures to reduce the overtopping potential of the dam.

Phase I Inspection Report written by GAI CONSULTANTS INC MONROEVILLE PA. and published by . This book was released on 1978 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual examination, as well as available engineering data, the dam is considered to be in good condition. Hydrologic and hydraulic calculations indicate that the facility can pass and/or store the flow resulting from the PMF. Additional calculations, however, indicated that if not properly vented, the morning glory spillway may pass through a period when a make and break siphoning action would attend flow. This action would be accompanied by surges at the inlet and outlet ends and by thumping and vibrations within the outlet. Since no design reports are available for the appurtenances, it is not known if this condition was considered during the design. Discussions with owners representatives and local residents also indicated that remedial repair to the outlet works was required at least once and possibly twice since construction. Consequently, it is recommended that a detailed hydraulic and hydrologic analysis be performed to accurately assess the present condition of the outlet and to make any modifications deemed necessary to insure that the outlet will perform adequately under all possible operating conditions.

Phase 1 Inspection Report written by and published by . This book was released on 1980 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stoughton Lake Dam is an earthfill dam with a maximum height of 23 feet and a crest length of 335 feet. The 90 feet crest length ogee spillway is located at the right abutment of the dam. The outlets works consist of an intake, a riser, a 36 inch corrugated metal pipe outlet conduit, and an outlet head wall. The riser is divided into two chambers by stop logs which can be removed to drawdown the reservoir. Hydraulic/hydrologic evaluations revealed that the spillway will pass the spillway design flood (SDF) on 53 percent of the Probable Maximum Flood (PMF) before overtopping will occur. Therefore, the spillway is assessed as being adequate. The dam was found to be in fair overall condition with the exception of the spillway training walls and the spillway discharge apron. The inspection revealed certain items of remedial work necessary for the dam which should be completed without delay by the owner.

Phase I Inspection Report written by Bernard M. Mihalcin and published by . This book was released on 1981 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and hydrologic/hydraulic analysis, the dam is considered to be in good condition. The size classification of the facility is small and the hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Since the facility is classified near the lower bounds of the small category, the SDF is considered to be the 1/2 PMF. Results of hydrologic and hydraulic analyses indicate the facility will pass and/or store approximately 40 percent of the PMF prior to embankment overtopping at the low area in the embankment crest (elevation 1177.4). Breach analysis indicates that failure under less than 1/2 PMF conditions could lead to increased downstream damage and potential for loss of life. Thus, based on screening criteria provided by the recommended guidelines, the spillway is considered to be seriously inadequate and the facility unsafe, non-emergency. Recommendations for owner action are listed.

Gilkerson Dam (NDI Number PA-01122 PennDER Number 65-8), Ohio River Basin, Unnamed Tributary to Beaver Run, Westmoreland County, Pennsylvania written by BAKER (MICHAEL) JR INC BEAVER PA. and published by . This book was released on 1980 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gilkerson Dam is classified as a 'Small' size - 'High' hazard dam. The dam was found to be in very poor overall condition at the time of the 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 40 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 Gilkerson Dam. The 1/2 PMF was chosen because the dam is on the low and end of the 'Small' size category. Because the total duration and maximum depth of overtopping during the 1/2 PMF (1.5 hours and 0.21 foot, respectively) did not meet the estimated limiting criteria for failure of the dam (2 hours and 1.0 foot), the spillway is assessed as 'inadequate' but not 'seriously inadequate'. It is recommended that the owner immediately initiate an engineering study to develop recommendations for remedial measures to reduce the overtopping potential of the dam.
