Phase I Inspection Report written by George Koch and published by . This book was released on 1981 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides information and analysis on the physical condition of the dam as of the report date. Information and analysis are based on visual inspection of the dam by the performing organization. Examination of available documents and a visual inspection of the dam did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some deficiencies which need to be evaluated and remedied. Using the Corps of Engineers' Screening Criteria for initial review of spillway adequacy, it has been determined that the dam would be overtopped by all storms exceeding 5% of the Probable Maximum Flood (PMF) inflows. While this dam has withstood overtopping in the past, it cannot be assured that overtopping will not eventually cause the dam to fail. Since failure of the dam would increase the hazard to downstream residents, the spillway capacity is adjudged as seriously inadequate and the dam is assessed as 'unsafe, non emergency'. The classification of 'unsafe' applied to a dam because of a seriously inadequate spillway is not meant to connote the same degree of emergency as would be associated with an 'unsafe' classification applied for a structural deficiency. It does mean that there appears to be a serious deficiency in spillway capacity and if a severe storm were to occur, overtopping and failure of the dam could take place, significantly increasing the hazard to loss of downstream of the dam. Inspection of the dam also revealed that there was a seepage problem on this structure. Seepage was exiting on the downstream slope and at the toe in the embankment section at the right end of the dam.

Phase I Inspection Report written by Hugh C. Flaherty and published by . This book was released on 1981 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides information and analysis on the physical condition of the dam as of the report date. Information and analysis are based on visual inspection of the dam by the performing organization. Examination of available documents and a visual inspection 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. Using the Corps of Engineers' screening criteria for the initial review of spillway adequacy, it has been determined that the embankment would be overtopped by the outflow resulting from all storms exceeding 17 percent of the Probable Maximum Flood (PMF) when the flashboards are in place and the overtopping discharge from the embankment portion of Norwich Reservoir No. 2 Dam (NY 349) is included as an inflow hydrograph. Dam overtopping, the resulting erosion of the embankment and hence, dam breaching would cause water surface levels downstream to reach depths which would pose significant danger to residents. Therefore, the spillway is adjudged to be seriously inadequate and the dam is assessed as unsafe, nonemergency.

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.

Book excerpt: This report provides information and analysis on the physical condition of the dam as of the report date. Information and analysis are based on visual inspection of the dam by the performing organization. Examination of available documents and a visual inspection 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. 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. (Author).

Download or read book National Dam Safety Program. Melody Lake Dam (Inventory Number N.Y. 748), Susquehanna River Basin, Cortland County, New York. Phase I Inspection Report written by George Koch and published by . This book was released on 1981 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual inspection of this dam and engineering analyses which have been performed revealed that several serious deficiencies exist on this structure. The worst of these deficiencies was the substantial amount of leakage through the dam. There were several areas of concentrated leakage along the interface between the dam and its foundation. Concentrated leakage such as this could adversely affect the stability of the structure. Immediately upon receipt of this notification, a system for providing around-the-clock surveillance of the dam during periods of unusually heavy precipitation should be developed and implemented. Structural stability analyses, based on available information, indicate that factors of safety against sliding are less than desireable for all conditions analyzed. When the dam is subjected to severe loading conditions such as an ice load or a water level at the top of the dam, the factors of safety fall to critical levels. It is recommended that within 3 months of the date of notification of the owner, investigations into the deficiencies on this structure should be commenced. An investigation into the leakage problem is required to determine a means of eliminating or controlling the leakage. Further studies of the structural stability of this structure are also required. Additional hydrologic and hydraulic investigations are required due to the seriously inadequate spillway. Remedial measures deemed necessary as a result of these studies should be completed within 18 months.
Book Synopsis National Dam Safety Program. Helderberg Lake Dam (Inventory Number NY276), Lower Hudson River Basin, Albany County, New York. Phase I Inspection Report by : George Koch
Download or read book National Dam Safety Program. Helderberg Lake Dam (Inventory Number NY276), Lower Hudson River Basin, Albany County, New York. Phase I Inspection Report written by George Koch and published by . This book was released on 1980 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Helderberg Lake Dam consists of a 285 foot long earth embankment with concrete cutoff wall and a 55 foot wide concrete channel spillway. The maximum height above the original stream bed is approximately 35 feet. Both the upstream and downstream slopes of the earth embankment are 1 vertical to 2 horizontal, and the crest width is 12 feet. The dam was reconstructed in 1944 after a failure of the original structure in 1938. The spillway crest was increased in length from 35 feet to 55 feet and lowered 2 feet. The original cutoff wall which is founded on bedrock was lengthened and increased in height by 2.25 feet. A 20 in. drain pipe was installed and incorporated into the tunnel that was in the original dam. The examination of documents and visual inspection of Helderberg Lake Dam and appurtenant structures did not reveal conditions which constitute a hazard to human life or property. The discharge capacity of the spillway is inadequate for all storms in excess of 50% of the PMF (Probable Maximum Flood).
