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.

Book Synopsis National Dam Safety Program. Goshen Reservoir Number 1 Dam (Inventory Number N.Y. 488), Lower Hudson River Basin, Orange County, New York. Phase I Inspection Report by : George Koch
Download or read book National Dam Safety Program. Goshen Reservoir Number 1 Dam (Inventory Number N.Y. 488), Lower Hudson River Basin, Orange County, New York. 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 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 George Koch and published by . This book was released on 1981 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mechanicville Reservoir Dam is an earth dam having a drop inlet spillway containing three discharge conduits plus a smaller cast-iron standpipe leading to a water supply conduit. The embankment is 380 feet long and about 30 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 20% of the Probable Maximum Flood (PMF) inflows.

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.

Phase I Inspection Report written by George Koch and published by . This book was released on 1981 with total page 105 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 Glenmere Lake 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 the initial review of spillway adequacy, it has been determined that the embankment would be overtopped for all storms in excess of 17% 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 not 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 life downstream of the dam.

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.
