This book was released on 1981 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arlington Reservoir Dam is an earth embankment with a concrete and rubble masonry overflow spillway (emergency spillway) located near the center of the dam. A concrete sluiceway (principal spillway), located approximately 20 ft, to the left of the emergency spillway, consists of a 9 ft. wide crest gate flowing to a 5 ft. diameter concrete pipe which outlets into Mill Brook. A low level outlet consists of a pipe of approximately 12 inches in diameter controlled by a gate valve which is located in a chamber at the downstream slope of the dam 800 ft, to the left of the sluiceway. The embankment has a minimum top width of approximately 20 feet, a maximum height of 14 feet and upstream and downstream slopes a minimum 1.5 H to 1 V. The overall length of the dam is approximately 1770 ft. Based on visual inspection and a review of all available pertinent data, the dam is considered to be in poor condition. Features that could effect the structural integrity of the dam include erosion and slumping of dam slopes, extensive tree growth on the dam clopes, deterioration of emergency spillway discharge channel, deterioration of the gate chamber for the low level outlet. The calculated Test Flood outflow from the reservior was 850 cfs. The Test Flood would overtop the dam by approximately 0.9 feet. About 600 cfs or 70% of the Test Flood outflow would be carried by the sluiceway and the emergency spillway.

This book was released on 1978 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam consists of an earth embankment approximately 630 ft. long and 40 ft. high with an ungated spillway about 40 ft. long at the center of the structure. The only outlet is a 24-in. pipe from a gate house intake located in the upstream slope. Based on a visual examination of the structure, the earth embankment and spillway are in good to fair condition. There was no evidence of settlement, lateral movement or other signs of structural failure or other conditions which would warrant urgent remedial treatment. The spillway has a capacity of 1790 cfs with flashboards removed and can pass the PMF outflow of 1530 cfs (750 csm) with the water level 0.6 ft. below the top of the concrete core wall.

This book was released on 1979 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: North Reservoir Dam is an earth embankment approximately 600 ft. long and 27 ft. high. An open channel spillway extends around the right abutment and a 19 ft. wide by 2 ft. high concrete weir is located at the spillway crest. The dam is in fair condition, based on visual examination of the structure. It is considered to be small in size and high in hazard potential.

This book was released on 1980 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fernwood Lake is impounded by three separate earth embankment dams believed to have been built in 1877. (There is also a 325 ft. long South Dike separating a portion of the south end of the lake; however, it has a low hazard potential and thus was excluded from inspection.) East Dam is approximately 100 ft. long and has a maximum height of 5 ft. Its 8-in diameter outlet pipe has been blocked. West Dam is approximately 400 ft. in length and a maximum of 11 ft. in height. It has a 14-in. diameter low-level outlet. The main dam at the north end of the lake is 450 ft. in length, 19 ft. in height and has a 19 ft. long spillway crest. The main Fernwood Lake (North) Dam - MA 00184 was the subject of a previous Phase I Inspection Report dated April 1979. The East and West dams are both in poor condition, based on visual examination of the structures. Hydraulic analyses indicate that the test flood outflow of 370 cfs (inflow 475 cfs or 913 csm) would overtop East Dam by 0.5 ft. and that a freeboard of 1.5 ft. would remain at West Dam. (A freeboard of 1.6 ft. would remain at North Dam and South Dike would be overtopped by 0.3 ft.) With the water level at the top of East Dam, the spillway capacity at North Dam with flashboards in place is about 80 cfs or 22 percent of the peak test flood outflow.

This book was released on 1978 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complex spillway is 77 ft. long and stands 12 ft. above stream bed at its lowest point. There are several houses close to the water's edge and in the watercourse downstream of the dam. The structure appears to be in fair condition, as is the left abutment and gatehouse. Owing to the impoundment storage, the dam falls within the intermediate size category. The hazard potential is significant. A failure of the dam coincident with full spillway discharge could result in a flow of about 7000 cfs. (Author).

This book was released on 1981 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lee Pond Dam consists of an earthen embankment with a natural spillway and a vertical stone masonry wall along two short sections of the downstream face. The embankment has a minimum top width of 15 ft. and a maximum height of 25 ft. The overall length of the dam is 870 ft., including the natural spillway at the right end of the dam which is about 15 ft. wide at normal pool elevation. The outlet works consist of an inoperable sluice gate located about 250 ft. from the left end of the dam. The dam impounds Lee Pond, which is used for recreational purposes. Maximum storage capacity at the top of dam is 220 acre-feet. Based on visual inspection and a review of all available pertinent data, the dam is considered to be in poor condition. Features that could effect the structural integrity of the dam are seepage at the downstream toe of the dam, erosion and slumping of dam slopes, extensive tree growth on the dam slopes and animal burrows on the crest and downstream face. The calculated test flood inflow of about 660 cfs results in a routed outflow of about 650 cfs. The spillway passes 100% of the test flood outflow with a freeboard of about 3 ft.

This book was released on 1981 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lynn Reservoir Dam, owned and operated by the City of Lynn, is an earthen embankment structure located in the central portion of Lynn, Massachusetts. The dam has a hydraulic height of 10 feet and is 1,920 feet long. The top width is 18 feet. As a result of the visual inspection and the review of available data, the Lynn Reservoir Dam is considered to be in poor condition. Major concerns are: deterioration of the concrete foundation of the outlet works building, badly corroded and perforated structural members of the outlet works control bridge; deterioration of the outlet works abutments, and apparent erosion on the downstream slope of the dam. The test flood pool would rise to within 0.6 feet of the embankment crest.

This book was released on 1979 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impounding structure at West Pond is a 123-foot long, 12-foot high earthfill dam with an overflow spillway at the east abutment. The spillway is located at the east abutment of the dam and consists of a notched ungated concrete weir with an overall length of 16 feet. The low point on the top of the dam is lower than the unnotched portion of the spillway. Based on the visual inspection of the site and a review of the limited data available on the dam, the dam is considered to be in poor condition and is in need of extensive repair work. The following deficiencies were observed at the site: moderate seepage below the toe of the dam; severe erosion of the upstream slope exposing the core wall; erosion of the top and downstream slope of the dam, localized buldging along the downstream slope; lack of a low level outlet; separation of the training walls from the spillway; seepage around and beneath the spillway; brush, timber, and debris in the discharge channel; and trees and vegetation growing on the slopes of the dam. The peak test flood outflow of 107 cfs will overtop the dam by a maximum of 1.3 feet. The spillway can discharge only 1.1 percent of the test flood before the dam is overtopped.

The dam is in fair condition. Evidence of seepage was noticed at the toe of the dam. The dam is intermediate in size and the hazard potential is high. Investigations are recommended to determine the stability of the embankment, the effect of seepage and the need and means of increasing the discharge capabilities at the facility. There are also a few remedial measures for the owner to undertake.
