This book was released on 1980 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long Pond Dam is located on Long Pond Brook about two (2.0) miles above Green River, a tributary of the Housatonic River in Great Barrington, Massachusetts. The dam is an earth embankment about 240 feet long with a vertical concrete core wall and a height of 15.4 feet, and maximum storage capacity at top of dam of about 700 acre feet. A concrete spillway with a crest length of 9.6 feet and a road bridge overhead is located in the right abutment; an 8-inch cast iron pipe drain near the center of the dam; one 10-inch cast iron water supply intake left of the dam center, and a second 14-inch cast iron water supply intake passes the left abutment. Water treatment facilities are located downstream of the left end of the dam. The pipe outlets are controlled by gate valves. The dam is in FAIR condition. The embankment is stable with no visible leakage. The dam top is not a uniform elevation and a few protective stones on the upstream face have fallen into the reservoir. Trees and shrubs are growing in the downstream slope of the dam. The spillway is in fair condition, but a stop log has been used to raise reservoir level for water works purposes and the approach channel retaining wall is tilting into the channel. The spillway and dam are adequate for 100 year frequency (1% probability) storm runoff though there would be little freeboard protection against wave action. A storm runoff of half probable maximum flood would raise the reservoir to about 0.9 feet above the top of the dam, assuming that the dam remained.

This book was released on 1981 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ashley Reservoir Dam is an earth embankment dam approximately 250 feet long and 33 feet high. The embankment has a top width of 12 feet with 2 1/2 H to 1V upstream slopes and 2H to 1V downstream slope. There is a 5-foot wide berm with a 3-foot wide stone gutter on the downstream slope. Between the berm and the downstream toe, the slope flattens to 2 1/2 H to 1V. There is a 70-foot long concrete overflow spillway. The spillway crest is 5 feet lower than the top of dam. Based on the visual inspection, the overall condition of the dam is fair. Spillway capacity with water at the elevation of the existing low points in the top of dam is 1700 cfs which is 57% of the test flood outflow.

A stone masonry spillway, 75 ft. long with a freeboard of 3.5 ft. is located at the east abutment. Since the dam is classified as intermediate in size with a high hazard potential, the test flood is the Probable Maximum Flood. There are a number of recommendations given in this report for implementation by the owner.

This book was released on 1979 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impounding structures at Fall Brook Reservoir include a 1392-foot long, 37-foot high main dam with a spillway and outlet, and a 256-foot long, 11-foot high dike. The spillway is located at the south abutment of the dam, and consists of a broad-crested weir 19 feet long with vertical stone masonry training walls that extend the length of the discharge channel. The outlet for the dam consists of a 30-inch diameter cast-iron pipe which discharges at the toe of th dam. The dam is generally in fair condition. The test flood outflow of 2,370 cfs and pool at El 657.6 will overtop the dam by 0.6 feet and the dike by 1.4 feet. The spillway capacity at El 646.2 (the low point on the crest of the dike) is 500 cfs, which is 21 percent of the test flood outflow.

This book was released on 1981 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Egypt Reservoir Dam is an earth embankment dam approximately 370 feet long, with a maximum hydraulic height of 34 feet. There is a 28-foot wide concrete chute spillway at the easterly abutment. The visual inspection indicates that the dam is in poor condition. The concrete spillway works are deteriorated and require major reconstruction. The downstream slope of the embankment shows evidence of instability and requires attention. Because the dam has a small size and high hazard potential classification, the test flood selected is the 1/2 Probable Maximum Flood (1/2 PMF). The test flood inflow for Egypt Reservoir, having a drainage area of 0.85 square miles, was estimated to be 1050 cfs. Effects of reservoir storage would not significantly reduce the test flood. This flow would cause the dam to overtop by about 1/2 foot. Spillway capacity at the low point in the top of the dam is 510 cfs which is 49% of the test flood outflow.

This book was released on 1978 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Onota Lake Dam consists of two adjoining structures: a 160 feet long stone masonry and concrete Main Dam, which creates Onota Lake, and a 375 feet long stone masonry, concrete and earthfill dam, which retains a small holding pond commonly referred to as the Canal. The maximum height of both dams is about 17.5 feet. Both dams have drop spillways which are 40 and 30 feet long, respectively, with 2.5 feet of freeboard. The Lake and Canal are interconnected by means of an uncontrolled 42 inch diameter pipe. A concrete intake structure and a 5 foot diameter steel outlet pipe are located at one end of the Canal. Discharges from the spillways and low level outlet flow into Onota Brook, a tributary of the Housatonic River. Phase I investigation of Onota Lake Dam does not indicate conditions which would constitute an immediate hazard to human life or property. Based on engineering judgment and the performance of the dams and the outlet works, the project appears to be in fair condition. The project, however, does have inadequacies and deficiencies which, if not remedied, have the potential for developing into hazardous conditions. The Test Flood was routed through the lake, using a computer routing technique, and resulted in the dam being overtopped by a maximum of 5.4 feet with a peak outflow discharge of 7388 cfs. The spillway capacity is only 6% of the Test Flood outflow and is considered seriously inadequate from a hydrologic and hydraulic viewpoint.

Book excerpt: The Greenwater Pond Dam is an earth embankment dam, approximately 320 feet long with a maximum hydraulic height of 18 feet. The dam is considered to be in fair condition. Because the dam is classified as intermediate size with a significant hazard potential, the test flood was selected as 50% of the Probable Maximum Flood.
