This book was released on 1981 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Melzingah Reservoir Dam on Gordons Brook, a tributary of the Hudson River, is 2 miles south of Beacon, New York. Melzingah Reservoir is one of three reservoirs used as a water supply for the City of Beacon, New York. Visual inspection revealed several deficiencies in this structure. The following items were noted: There are two large seeps at the base of the spillway; Water was flowing (3-5 gpm) from beneath the spillway; Five minor seeps were found 3 to 7 feet above the toe of the dam between the spillway and left abutment; Trees and brush are growing along the toe of the dam; There are small trees growing in the discharge channel; The gunite surface of the dam is deteriorating and is cracked over the entire upstream and downstream faces; An irregularity or 'bump' in the gunite surface was observed on the downstream face of the dam, approximately 200 feet from the left abutment; The junction of the 24-inch pipe and the 12-inch water supply line is leaking, and A construction joint has deteriorated on the upstream crest of the dam approximately 75 feet from the left abutment, creating a void approximately 4 inches deep, 2 feet long, and 2 feet wide.

This book was released on 1981 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examination of available documents and visual inspection of the dam and appurtenant structures did not reveal any conditions which constitute an immediate hazard to human life or property. Using the Corps of engineers' screening criteria, it has been determined that the dam would be overtopped for all storms exceeding 33 percent of the Probable Maximum Flood (PMF). Therefore, the spillway is adjudged as 'seriously inadequate' and the dam is assessed as 'unsafe, non-emergency.' Structural stability analyses based on available information, indicate that factors of safety against overturning are generally low, and the locations of the resultants fall outside of the middle 1/3. The factor of safety against sliding was less than the recommended value of 3 for Cases 3 and 4. Therefore, when the dam is subjected to severe loading conditions such as a 1/2 PMF of PMF event, the factors of safety fall to below critical levels.

This book was released on 1981 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examination of available documents and a visual inspection of the dam and appurtenant structures did not reveal conditions which constitute an immediate hazard to human life or property. It has been determined that the dam would be overtopped for all storms exceeding approximately 23 percent of the Probable Maximum Flood (PMF). Therefore, the spillway is adjudged 'seriously inadequate', and the dam is assessed as unsafe, non-emergency. It is recommended that, within three months of owner notification, detailed hydrologic and hydraulic investigations of the structure should be undertaken to more accurately determine the site-specific characteristics of the watershed and their effects upon the overtopping potential of the dam. The results of this investigation and analyses will determine the appropriate remedial measures 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 must be provided during these periods.

This book was released on 1981 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sagamore Lake Dam (formerly known as the Old Forge Dam) is an earth dam with a concrete corewall. A concrete gravity spillway section is located near the left end of the dam. The dam is approximately 300 feet long and 20 feet high. 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 13% of the Probable Maximum Flood (PMF) inflows.

This book was released on 1981 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The examination of documents and the visual inspection of Lake Mahopac Dam and its appurtenant structures did not reveal conditions which constitute an immediate hazard to human life and property. Using Corps of Engineers screening criteria, it has been determined that the dam would be overtopped for all storms exceeding approximately 56 percent of Probable Maximum Flood (PMF). The maximum spillway discharge capacity is 7.9 percent of the PMF peak outflow. The spillway is, therefore, adjudged as 'inadequate'. The following remedial measures should be performed within 12 months from notification: (1) Missing portions of the upstream stone masonry wall should be repaired. (2) Brush and shrubbery should be removed from the embankment, spillway-reservoir drain structure and downstream channel. Provide a program of periodic cutting and or mowing of the dam surfaces, spillway-reservoir drain structure and the downstream channel. (3) The collected debris at the spillway-reservoir drain structure and in the downstream channel should be removed and hauled away from the dam. (4) A program of periodic inspections and maintenance of the dam and appurtenances should be provided, including yearly operation and lubrication of the reservoir drain and its control facilities. This information should be documented for future reference. (5) An emergency action plan for the project should be developed.

This book was released on 1980 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The examination of documents and the visual inspection of Tivoli Lake (Cranberry Lake) did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some deficiencies which require further investigations and remedial actions. Using Corps of Engineers screening criteria for the initial review of spillway adequacy, it has been determined that the dam would be overtopped for all storms exceeding approximately 38 percent of the Probable Maximum Flood (PMF). 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. It does mean, however, that based on an initial screening, and preliminary computations, there appears to be a serious deficiency in spillway capacity so that if a severe storm were to occur, overtopping and failure of the dam would take place, significantly increasing the hazard to loss of life downstream from the dam.

This book was released on 1981 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dam is located on the Agawamuck Creek in the Village of Philmont. It is approximately 1000 feet south of New York State Route 217. This dam was constructed about the year 1860 by the High Rock Knitting Company, who used it for industrial purposes. Visual observations revealed several deficiencies on this structure. The following items were noted: Voids created by displaced stones on the downstream face. Voids ranged in size from 1 cubic foot up to 60 cubic feet; Leakage through and beneath the structure; Weathered stones which compose the dam that can be broken off by hand; Deteriorated concrete on the crest of the dam, and Brush and vines growing on the dam.
