Phase I Inspection Report written by BERGER ASSOCIATES INC HARRISBURG PA. and published by . This book was released on 1978 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Opposum Lake Dam is a zoned rolled earthfill dam with an impervious core. Construction was completed in June 1961. It was inspected 5 April 1978. This dam does not have the capacity to pass the recommended spillway design flood of one-half the Probable Maximum Flood without overtopping. The spillway capacity is not considered seriously inadequate, as the project will pass the 100-year flood. A serious and persistent problem exists in a constant seepage passage over most of the length of the downstream slope of the dam. It is recommended that the owner maintain continual surveillance of the dam until the embankment has been rehabilitated to correct the serious seepage problem.

Phase I Inspection Report written by BERGER ASSOCIATES INC HARRISBURG PA. and published by . This book was released on 1978 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Bear Gap Dam no. 6 is an earth fill dam with a rock core which is founded on rock in a cutoff trench. It was completed in 1915. Based on a visual inspection (June 13, 1978), past performance and available engineering data, the dam and its appurtenances appear to be in fair condition. The following recommendations are made: (1) The owner shall make a detailed hydrologic and hydraulic analysis for this dam and improve the spillway capacity to meet the requirements of this study; and (2) The owner shall carefully monitor the seepage on the dam and take remedial action if seepage increases or if turbidity in the seepage water is discovered or if embankment sloughage would occur. In accordance with the Corps of Engineers' evaluation guidelines, the spillway capacity is inadequate to pass the PMF(Probable Maximum Flood) without overtopping the dam. The spillway capacity is capable of passing only 34% of the PMF peak inflow and, therefore, it is considered to be seriously inadequate. A formal surveillance and downstream warning system shall be developed by the owner to be used during periods of high precipitation.

Download or read book National Dam Safety Program. Parker Dam (NDI Number PA 01126, PennDER Number 17-87), Susquehanna River Basin, Laurel Run, Clearfield County, Pennsylvania. Phase I Inspection Report written by John A. Dziubek and published by . This book was released on 1980 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parker Dam is classified as a 'Significant' hazard - 'Small' size dam. The dam and reservoir, owned by the Commonwealth of Pennsylvania, Department of Environmental Resources, are used for recreational purposes. The dam and appurtenant structures were found to be in good overall condition at the time of the inspection. 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 Parker Dam. Since the dam is in the middle of the 'Small' size category according to storage capacity, the 1/2 PMF was selected as the SDF. Hydrologic/hydraulic evaluations, performed in accordance with procedures established by the Baltimore District of the U.S. Army Corps of Engineers, revealed that the available spillway capacity is much greater than the maximum flow expected during the SDF. Therefore, the dam will not be overtopped during the SDF and the spillways are considered to be 'adequate'.

Download or read book National Dam Safety Program. Clayton's Dam (Inventory Number NY 1460), Susquehanna River Basin, Madison County, New York. Phase I Inspection Report written by Hugh C. Flaherty and published by . This book was released on 1981 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examination of available documents and visual inspections of the dam did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some deficiencies that need to be evaluated and remedied. The spillway is adjudged to be seriously inadequate and the dam is assessed as unsafe, nonemergency. It should be noted that Eaton Brook Reservoir Dam is located approximately 2.2 miles upstream of Clayton's Dam on Eaton Brook. Its spillway has also been adjudged to be seriously inadequate and the dam assessed as unsafe, nonemergency. Due to the appreciable size of Eaton Reservoir, the breaching of that dam would undoubtedly have a serious effect on Clayton's Dam. Similarly, the failure of either of these dams would have a serious effect on two small dams also on Eaton Brook, located 0.5 miles and 1.7 miles downstream of Clayton's Dam.

Phase I Inspection Report written by Bernard M. Mihalcin and published by . This book was released on 1980 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and available engineering data, the dam is considered to be in good 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. Due to the high potential for damage to downstream structures and possibly loss of life, the SDF is considered to be the PMF. Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store approximately 92 percent of the PMF prior to embankment overtopping. Based on screening criteria contained in the recommended guidelines, the spillway is considered to be inadequate, but not seriously inadequate. Deficiencies noted by the inspection team included a seepage condition along a portion of the downstream embankment toe approximately 160 feet to the right of the left abutment hillside and a minor vertical crack in the concrete spillway overflow wall.

Phase I Inspection Report written by Hugh C. Flaherty and published by . This book was released on 1981 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: Little Choconut Watershed Site 2A Dam is one of eight floodwater retarding dams in the Little Choconut, Finch Hollow, and Trout Brook watersheds designed to reduce floodwater damages. The dam embankment is approximately 530 feet long, 33 feet high and has an upstream slope of 3 horizontal to 1 vertical and a downstream slope of 2.5 to 1. The principal spillway is a drop inlet structure consisting of a single stage reinforced concrete riser, a 24 inch diameter prestressed concrete cylinder pipe and a channel excavated into bedrock at the outlet of the conduit. The emergency spillway is a curved 80 foot wide channel with 3 to 1 side slopes cut into earth at the left abutment. Hydrologic/hydraulic analyses performed in accordance with the Corps of Engineers' Recommended Guidelines for Safety Inspection of Dams indicate that the principal spillway and the emergency spillway would pass 100 percent of the outflow from the Probable Maximum Flood (PMF) without overtopping the dam. Therefore, the combined spillway capacity is adjudged to be adequate.

Flaherty and published by . This book was released on 1981 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the basis of the visual examination, there were no signs of impending structural failure or other conditions which would warrant urgent remedial action; however, a number of serious deficiencies were noted. Since there were no drawings available, the evaluation of this dam is based primarily on visual examination, limiting measurements at the site, approximate hydraulic and hydrologic computations, and application of engineering judgement. It is recommended that the following additional investigations be performed by a registered professional engineer engaged by the owner: (1) The present embankment sections adjacent to the spillway represent a potential hazard to the dam with respect to possible erosion, piping and/or failure of the dam during high reservoir levels. Therefore, regrade this to make the embankment section conform to the embankment cross sections elsewhere. In addition, adequately protect these sections from spillway outflows; and (2) Investigate the seepage that was observed near the downstream toe of slope, including observation during high and low reservoir levels, evaluate the cause and recommend appropriate remedial measures.

Phase I Inspection Report written by Michael Baker (III.) and published by . This book was released on 1981 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of a Phase I Inspection is to identify expeditiously those dams which may pose hazards to human life or property. The assessment of the general conditions of the dam is based upon available data and visual inspection. Detailed investigation and analyses involving topographic mapping, subsurface investigations, testing, and detailed computational evaluations are beyond the scope of a Phase I investigation; however, the investigation is intended to identify any need for such studies. Based upon the field conditions at the time of the field inspection and all available engineering data, the Phase I report addresses the hydraulic, hydrologic, geologic, geotechnic, and structural aspects of the dam. The engineering techniques employed give a reasonably accurate assessment of the conditions of the dam. It should be realized that certain engineering aspects cannot be fully analyzed during a Phase I inspection. Assessment and remedial measures in the report include the requirements of additional indepth study when necessary. Phase I reports include project information of the dam appurtenances, all existing engineering data, operational procedures, hydraulic/hydrologic data of the watershed, dam stability, visual inspection report and an assessment including required remedial measures.
