Phase I Inspection Report written by Granville Kester (Jr) and published by . 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.

Download or read book National Dam Safety Program. Sparkle Lake Dam (Inventory Number N.Y. 1330), Lower Hudson River Basin, Westchester County, New York. Phase I Inspection Report written by Eugene O'Brien and published by . This book was released on 1981 with total page 77 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 Sparkle Lake Dam and appurtenant structures 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 Corps of Engineers screening criteria for initial review of spillway adequacy, it has been determined that the dam would be overtopped for all storms exceeding 48 percent of Probable Maximum Flood (PMF). The overtopping of the dam could cause the erosion of both abutments and the downstream face of the dam resulting in dam failure, thus significantly increasing the hazard to life and property downstream. The pipe spillway is, therefore adjudged as seriously inadequate and the dam is assessed as unsafe, non-emergency.

Phase I Inspection Report written by George Koch and published by . This book was released on 1981 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is located on an unnamed tributary of the Bozen Kill, a tributary of the Normans Kill and the Lower Hudson River, approximately 2.3 miles west of the Village of Altamont. The dam provides storage for the supply of water to the Village of Altamont. The problem areas observed during the inspections and the recommended remedial actions are as follows: Cracking and movement of the right spillway chute wall was observed. Removal of backfill, installation of weeps and stiffening of the wall should control this problem; Seepage was observed resulting from deterioration of the construction joints and cracking of the spillway concrete. Vegetation was also noted growing in the joints of the spillway chute slabs. All construction joints require cleaning and recaulking to reduce seepage and inhibit infiltration through the spillway chute and core wall; Cracking of the exposed core wall, spillway buttresses, return walls and spillway chute slabs were observed. These areas require repair. Monitor the deterioration of the catwalk and repair as required, and Monitor the seepage observed at the base of the spillway chute and at the reservoir drain outlet. If seepage increases significantly, investigate and repair.

Book excerpt: Cornwall Upper Reservoir Dam, located on an unnamed tributary of Moodna Creek, is 2 miles south of Cornwall-on-the-Hudson, New York. The dam and reservoir are used for water supply. The visual inspection revealed several deficiencies in this structure. The following items were noted: The left spillway training wall and the adjacent crest elevation are 0.9 feet below the average crest of the dam; Superintendent Ralph Smith reported seepage near a large tree (24-inch diameter) on the downstream face near the left abutment of the dam. Some seepage was observed in this area, but the source could not be determined; Four small local depressions along the crest of the dam; Trees are located in the discharge channel immediately downstream from the spillway; On the downstream slope, there are four or five tree trunks with diameters 4 to 8 inches. On the downstream slope there are a large number of trees below the road; The masonry portion of th left spillway wall has collapsed for approximately 3 feet long at the crest of the spillway weir; A large number of rodent holes are scattered on the downstream face of the dam; and There is a small eroded area on the downstream face of the dam near the left abutment.

Phase I Inspection Report written by Granville Kester (Jr) and published by . This book was released on 1981 with total page 102 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. It has been determined that the dam would be overtopped for all storms exceeding approximately 28 percent of the Probable Maximum Flood (PMF). The spillway is, therefore, adjudged as 'seriously inadequate' and the dam is assessed as unsafe, non-emergency. It is recommended that, within 3 months of notification of the owner, 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 these investigations and analyses will determine the appropriate remedial measures which will be required. 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. Current inspection and maintenance procedures by the owner are inadequate. Monitoring of the reservoir levels should be expanded to include readings during peak flow periods.
