This book was released on 1978 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Vly Creek Dam is composed of a 24.5 feet high and 338 feet long earth embankment dam with spillway, and a 39.5 feet high and 1720 feet long earth embankment dike with control tower for water supply regulation. Visual inspection did not reveal conditions that are considered to be unsafe. The total discharge capacity of the spillway is adequate to pass half the Probable Maximum Flood (PMF) regardless of the flashboards. The spillway is also capable of discharging PMF without flashboards, but not with flashboards.

This book was released on 1981 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The examination of documents and visual inspection of Basic Creek 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 52% of the PMF (Probable Maximum Flood). During the 1/2 PMF event the water surface will approximate the top of dam elevation and the outflow will be 6801 cfs. The spillway is, therefore, assessed as 'inadequate'. The following problem areas were observed which require remedial action within 1 year of notification to the owner: Repair the areas of deteriorated concrete which are leaking (approx. 50 gpm) between the 24 inch and 48 inch valves within the intake chamber; Repair the deteriorated concrete and control the seepage within the diversion tunnel; Monitor the seepage within the intake chamber, particularly above the 12 inch valve, and repair as required; Repair the voids in the concrete spillway apron; Monitor the seepage from the horizontal joints of the spillway; Periodically monitor the concrete deterioration of the dam and appurtenances; Periodically remove the debris in the downstream channel; Remove the trees and brush on the slopes, crest and abutments of the embankments.

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: 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.

This book was released on 1980 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Helderberg Lake Dam consists of a 285 foot long earth embankment with concrete cutoff wall and a 55 foot wide concrete channel spillway. The maximum height above the original stream bed is approximately 35 feet. Both the upstream and downstream slopes of the earth embankment are 1 vertical to 2 horizontal, and the crest width is 12 feet. The dam was reconstructed in 1944 after a failure of the original structure in 1938. The spillway crest was increased in length from 35 feet to 55 feet and lowered 2 feet. The original cutoff wall which is founded on bedrock was lengthened and increased in height by 2.25 feet. A 20 in. drain pipe was installed and incorporated into the tunnel that was in the original dam. The examination of documents and visual inspection of Helderberg Lake 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 50% of the PMF (Probable Maximum Flood).

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.
