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 Granville Kester (Jr) and published by . This book was released on 1981 with total page 91 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 any 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 32 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 this investigation 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.

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.

Stetson and published by . This book was released on 1980 with total page 91 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. Mine Lake Dam is classified as a small dam with a significant hazard potential. The dam is constructed of masonry and is 13.9 feet high and 516 feet in length. Over 300 feet of the dam's length is less that 8 feet in height. The dam's reservoir is only 25 acres. Popolopen Dam is located one mile above Mine Lake, while Stilwell Dam and reservoir is located a few hundred feet below Mine Lake Dam. The drainage area of the dam is 8.7 square miles. The structure forms an impoundment which is used for recreational purposes on the West Point Military Reservation. Hydrology computations prepared according to the Corps of Engineers' screening criteria establishes the spillway capacity of 1,492 cfs at 9.9 percent of the PMF with the PMF discharge at 15,070 cfs and the 1/2 PMF discharge at 7,170 cfs. Since the spillway cannot pass the 1/2 PMF discharge without overtopping the dam, the spillway is inadequate. The stability analysis determined three loading cases where the dam was unstable. Each of these cases involved uplift on the base of the dam due to hydrostatic forces in combination with the PMF, seismic loadings or ice loadings. Only the ice load occurs in a normal operating situation. The condition of uplift is plausible since seepage was observed at the juncture of the masonry spillway with the bedrock.

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.
