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 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.

Book excerpt: This dam is about 450 ft. long including the spillway and has a maximum height of about 36.5 feet. The facility is considered to be in fair condition. This classification is based on steep slopes and some erosion at both the upstream and downstream faces of the earth embankments. The size is small and the hazard potential is significant. Investigations are recommended to determine the stability of the embankment.

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.

This book was released on 1981 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pecks Pond Dam is a stone masonry and earth embankment dam approximately 490 feet long with a maximum hydraulic height of 31 feet and a top of dam storage of 155 acre-feet. The dam has a variable top width of between 8 feet and 20 feet and side slopes of approximately 2H to 1V. Discharge is over a grouted stone masonry spillway which has a length of about 40 feet. There is now a partial breach in the spillway. The bottom of the breach opening is 11 feet below the original spillway crest and 13 feet below the top of the dam. The dam presently impounds about 15 acre-feet. The storage capacity at the elevation of the test flood is 150 acre-feet. Based on engineering judgment and past performance of the dam and outlet works, the project is considered to be in poor condition. The breaching activities have left a portion of the embankment in an unstable condition and subject to erosion by discharge through the breach in the spillway. A 5-foot diameter penstock has been partially removed; however, discharge through the penstock is still possible and could cause erosion of a large portion of earth embankment. The spillway capacity at the top ot the dam is 108% of the test flood outflow. However, because of the structural condition of the spillway and adjacent walls, it is unlikely that the dam could safely pass high discharges.

This book was released on 1979 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shaker Mill Pond Dam consists of a gunite covered concrete and masonry spillway structure between approach channel walls and abutting earth roadway embankments. The overall length of the dam is about 50 ft. and its maximum height is 20.4 ft. There are two regulating outlets at the dam site. The dam is in fair condition, based on a visual examination of the structure. Several deficiencies, mainly due to deterioration, were noted. However, there was no evidence of settlement, lateral movement or other signs of structural failure of the dam, or other conditions which would warrant urgent remedial action. With the water level at the top of dam (level of Route 102 bridge deck), the ungated spillway capacity is approximately 1,600 cfs which is 6 percent of the test flood outflow.
