This book was released on 1980 with total page 73 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. The examination of documents and the visual inspection of Panama Dam did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some deficiencies which require additional studies to further evaluate conditions affecting the dam. Using the Corps of Engineers Screening Criteria for the initial review of spillway adequacy, it has been determined that the embankment would be overtopped for all storms in excess of 5% of the PMF (Probable Maximum Flood). This determination has been confirmed by the overtopping of the dam during the September 14, 1979 storm, which resulted in the need for evacuation of Panama Village residents and the closing of NYS Route 474 due to extensive erosion. The spillway is therefore, 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.

Phase I Inspection Report written by Bent L. Thomsen and published by . This book was released on 1980 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 require further investigation and remedial action. Using the Corps of Engineers screening criteria for review of spillway adequacy, it has been determined that the dam would be overtopped for all storms exceeding approximately 75 percent of the PMF. The spillway is, therefore, considered to be 'inadequate'. A review of the structural stability analysis performed by the designer indicated calculated safety factors against sliding to be less than recommended minimum value. A more detailed analysis which was performed as a part of this Phase I investigation produces a similar conclusion. Therefore, it is recommended that within 6 months of notification to the owner a detailed field investigation and monitoring program be undertaken to determine the actual hydrostatic uplift pressures along the base of the dam and that further detailed structural stability analyses be performed using this information. Debris should be removed from the upstream face of the dam as part of the routine maintenance program. Finally, leakage along the south side of the south tainter gate should be monitored on a daily basis with these observations documented in the dam operator's log book.

This book was released on 1980 with total page 173 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. The examination of available engineering documents and visual inspection of the Conewango Creek Watershed Project - Site 33 dam did not disclose conditions which constitute a hazard to downstream human life or property. The total discharge capacity of the combined principal and auxiliary spillways is adequate to impound and safely discharge the floodwater resulting from the Probable Maximum Flood (PMF). A number of minor deficiencies were noted on this structure. These deficiencies include: debris around the trash racks of the orifice in the riser intake structure, debris (logs) on the lower half of the upstream slope as measured from the crest to the normal pool elevation, slight erosion along abutment- embankment contacts on lower third of downstream slope, damaged internal drainage pipes above plunge pool, small animal burrow on downstream slope just above riprap around the principal spillway outlet pipe, wet areas beyond downstream toe in waste area along east side of outlet channel and natural flood plain on the west side of the outlet channel.

Phase I Inspection Report written by George Koch and published by . This book was released on 1979 with total page 115 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. The examination of documents and visual inspection of the Site 19 dam and appurtenant structures did not reveal conditions which constitute an immediate hazard to human life or property. The dam, however, has a number of problem areas, which if not remedied, have the potential for developing into hazardous conditions. These problem areas are as follows: 1. Seepage encountered at the toe of the downstream slope near the left (north) abutment contact; 2. Erosion at the left abutment contact of the downstream face caused by runoff from the very steep abutment slope; 3. Incomplete structural stability investigations which did not include seismic and the observed seepage forces.

Stetson and published by . This book was released on 1981 with total page 182 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. The examination of documents and visual inspection of the Marcy Reservoir Dam did not reveal conditions which constitute an immediate hazard to human life or property. The dam, however, has a number of problem areas which require further investigation and remedial work. It is, therefore, recommended that within 6 months of notification to the Owner, a detailed hydrologic/hydraulic investigation of the structure should be undertaken to more accurately determine the site specific characteristics of the watershed and their effect upon the overtopping potential of the dam. The results of these investigations will determine the appropriate remedial measures which will be required to achieve a spillway capacity adequate to discharge the outflow from at least the 1/2 PMF. In the interim, a detailed emergency action plan must be developed and implemented during periods of unusually heavy precipitation. Also, around-the-clock surveillance of the structure must be provided during these periods.

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 George Koch and published by . This book was released on 1979 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ephratah Dam is 760 feet long, buttressed concrete and cyclopean masonry dam containing an ogee spillway, 3 arched sections, a concrete gravity section and an earth embankment section. The maximum height of the dam is 65 feet. The ogee spillway is 251 feet long and has a crest elevation of 974.15. A 3 feet diameter reservoir drain is located at the base of the middle arched section. The flow of the drain is controlled by a manually operated butterfly valve located in the building at the toe of the dam. The power generation intake system is located on the upstream face of the south abutment. A 6.5 feet diameter wood stave pipe carries water from the intake 2 miles to the power plant. All regulating outlets are operational. The concrete portions of the dam exhibit signs of major deterioration as indicated by the extensive seepage which appears on the downstream face. Gunite and epoxy injection treatments have failed to control the flow. The discharge capacity of the spillway is inadequate for all flow in excess of 17% of the Probable Maximum Flood (PMF). The spillway is not considered seriously inadequate, based on the Corps of Engineer's Screening Criteria, since the dam is a gravity structure and the stability analyses indicate that the dam is not unstable during a PMF event.
