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.

Phase I Inspection Report written by George Koch and published by . This book was released on 1981 with total page 100 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 the Goshen Reservoir did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some problem areas which require additional studies and remedial work. The most serious of these deficiencies are the two areas of seepage on the downstream slope of the dam. First is at the end of a grouted stone spillway channel and the second is at the toe in the center of the dam. It is recommended that within six months from notification, an engineering investigation is initiated to determine the sources of the seepage found. 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 all storms in excess of 51% of the Probable Maximum Flood (PMF). Therefore, the spillway is adjudged as 'inadequate.' (Author).

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.

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.

Phase I Inspection Report written by Eugene O'Brien and published by . 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.

Phase I Inspection Report written by Granville Kester (Jr) and published by . This book was released on 1981 with total page 81 pages. Available in PDF, EPUB and Kindle. 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 George Koch and published by . This book was released on 1981 with total page 109 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 Delmar Reservoir No. 1 Dam did not reveal conditions which constitute a hazard to human life or property. Since this is a storage reservoir with an embankment entirely surrounding the pond area, the hydraulic/hydrologic analysis was not performed in the usual manner of modeling a watershed area. The drainage area for this structure was limited to the reservoir itself. From normal water surface elevation to the top of the dam, the Probable Maximum Flood can safely be stored and discharged through the overflow pipe. Therefore, the spillway is therefore assessed as adequate. (Author).

Stetson and published by . This book was released on 1978 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Authority for this report is provided by the National Dam Inspection Act, Public Law 92-367 of 1972. It has been prepared in accordance with a contract for professional services between Dale Engineering Company and The New York State Department of Environmental Conservation. The purpose of this inspection is to evaluate the structural and hydraulic condition of the Indian Brook Dam and appurtenant structures, owned by the Village of Ossining, New York, and to determine if the dam constitutes a hazard to human life or property and to transmit findings to the state of New York. This Phase I inspection report does not relieve an owner or operator of a dam of the legal duties, obligations or liabilities associated with the ownership or operation of the dam. In addition, due to the limited scope of services for these Phase I investigations, the investigators had to rely upon the data furnished to them. Therefore, this investigation is limited to visual inspection, review of data prepared by others, and simplified hydrologic, hydraulic and structural stability evaluations where appropriate. The investigators do not assume responsibility for defects or deficiencies in the dam or in the data provided.

Phase I Inspection Report written by George Koch and published by . This book was released on 1981 with total page 116 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 with this structure. Structural stability analyses, based on available information, indicate that this dam is marginally stable under normal loading conditions and is unstable when subjected to severe loading conditions (such as flood flows or ice loading). Seepage noted under and through the structure, creating wet, soft areas along the downstream toe along both ends of the dam, 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. An emergency action plan for the notification of downstream residents should also be developed. It is recommended that within 3 months of the data of notification of the owner, investigations into the deficiencies on this structure should be commenced. Studies of the structural stability and seepage problems, including subsurface and structural explorations are necessary. Information obtained should be incorporated into a detailed stability evaluation.

Phase I Inspection Report written by George Koch and published by . This book was released on 1981 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examination of documents and visual inspection of the Watervliet Upper 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 55% of the PMF (Probable Maximum Flood). During the 1/2 PMF event, the maximum water surface will be 1.2 feet below top of dam. However, the dam will be overtopped by 2.3 feet during the full PMF; therefore, the spillway is assessed as Inadequate.
