Dziubek and published by . This book was released on 1980 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pine Run Dam is classified as a 'Small' size - 'Significant' hazard dam. The dam, owned by the Mercer County Commissioners, is used to reduce floodwater damages in the Little Shenango Watershed. The dam and appurtenant structure were found to be in good condition at the time of the inspection. Hydraulic/hydrologic evaluations, performed in accordance with procedures established by the Baltimore District, U.S. Army Corps of Engineers, for PHase I Inspection Reports, 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 100-year flood to the 1/2 Probable Maximum Flood (1/2 PMF) is required for Pine Run Dam. The spillway is therefore considered to be 'adequate'. The visual inspection and review of information did not reveal any problems or deficiencies which require remedial action by the owners of the dam at this time. It is recommended that the owners continue their inspections and maintenance programs to maintain the dam in good condition. (Author).

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 John A. 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.

Phase I Inspection Report written by and published by . This book was released on 1981 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and hydrologic and hydraulic analysis, 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 ranges between the 1/2 PMF (probable Maximum Flood) and the PMF. Since the facility is classified near the upper bounds of the small category with regard to available storage capacity, the SDF is considered to be the PMF. Results of the hydrologic and hydraulic analysis indicate that under existing conditions the facility will pass and/or store only about 17 percent of the PMF prior to embankment overtopping at the low area adjacent the left abutment. If the low area were regraded to the design top of dam, the spillway system would then pass about 28 percent of the PMF prior to embankment overtopping. Under existing conditions, spillway discharges are controlled by the existence of a township-owned roadway embankment and culvert that is situated about 100 feet downstream of the spillway weir.
