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.

This book was released on 1980 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examination of available documents and a visual inspection of the dam revealed several deficiencies which may affect the safety of the dam. There was serious leakage in the vicinity of one of the gates in the gatehouse section. The auxiliary spillway section had failed allowing a portion of the river to flow around the left end of the dam. In addition to these observed deficiencies, structural stability analyses performed for the main spillway section indicate that the structure is unstable when subjected to severe loading conditions such as ice loading or flood flows. Further analysis is required. These studies should include subsurface and structural investigations to obtain information about the condition of the structure and its foundation. This information should then be incorporated into a more detailed stability analysis. The spillway, not having sufficient discharge capacity for passing one-half the Probable Maximum Flood (PMF), is considered to be inadequate. For such a large storm event, a high tailwater condition would occur, resulting in the flooding of downstream hazard areas. Hence, dam failure from overtopping would not significantly increase the hazard to loss of life from that which would exist just before failure. Several other deficiencies were also noted on this structure. Among these were deteriorated concrete on the main spillway section, erosion at the east abutment, and minor sloughing at the west abutment. In addition, no emergency action plan exists for this structure.

This book was released on 1979 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Feeder Dam at Glens Falls is a concrete gravity dam having a 615 foot long ungated river spillway section with flashboards including a 20 foot wide inclined logway. Examination of available documents and a visual inspection of the dam did not reveal conditions which constitute an immediate hazard to human life or property. However, significant deficiencies and deterioration was observed at one portion of the dam, the North Bulkhead, so as to warrant additional study and analysis as well as corrective action by maintenance forces. The spillway capacity of the dam, although not having sufficient discharge capacity for passing one-half the Probable Maximum Flood (PMF), is considered to be inadequate. Other deficiencies found during the visual inspection concerned concrete surface deterioration and cracking, non-operable or non-existent gate machinery, and an overall need for increased maintenance of the dam.

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.

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.
