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.

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 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 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 1978 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whiting Pond Dam is approximately 600 ft. long, has a maximum height of 9 ft, and includes a 13-ft. long concrete spillway. The dam is in fair condition, based on a visual examination of the structure. Although some deficiencies were noted, there no evidence of settlement, lateral movement or other signs of structural failure or other conditions which would warrant urgent remedial action. The PMF outflow of 4160 cfs (1015 csm) would overtop the spillway platform by about 2.6 ft. and most of the embankment by 1 to 1.5 ft. With the water at the level of the platform, the spillway (without flashboards) can pass 312 cfs which is 7.5 percent of the test flood.

This book was released on 1980 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crocker Pond Dam is a 520-foot long earthfill dam built in 1933 for storage. The facility has a maximum height of 38.5 feet and includes a spillway, flood gate, gate house and outlet structures. The spillway is a concrete ogee weir, 120-feet long (including the closed flood gate). There are five separate outlets for the dam, and 8-foot wide by 12-foot high flood gate, which when closed is part of the spillway; a 42-inch diameter main low level outlet; a 24-inch diameter auxiliary low level outlet; a 3-foot square drain; and a 3-foot square trash chute. The following deficiencies were observed at the site: spalled, cracked and deteriorated concrete on the east and west approach channel sidewalls, the spillway face, the sidewall between the spillway and the flood gate, the east and west sidewalls of the spillway, and the west face of the gate house; burrow holes and foot paths on the downstream face of the dam; missing stones along the downstream bench of the east section of the dam; logs and debris caught on the spillway weir and trees overhanging the west side of the downstream channel. The test flood would overtop the dam by 2.2 feet with no flashboards in place andf 3.8 feet with flashboards in place. Hydraulic analyses indicate that the spillway without flashboards can discharge 10,500 cfs, or 57 percent of the test flood outflow before the dam is overtopped with flashboards, the spillway can discharge 6,300 cfs or 34 percent of the test flood outflow before the dam is overtopped. This assumes that the flood gate remains closed during the test flood.

The upstream face is overgrown and eroded, the embankment crest deteriorated and abused by improper usage. It falls within the small size category and in the high hazard category. Failure of the dam would cause a flood through a thickly settled area.

Book excerpt: It is an earthfill structure with a concrete core that is about 1390 ft. long having a maximum height of 60 ft. The dam is fair condition, there being several motorbike trails and footpaths on the downstream slope. It is intermediate in size and has a hazard potential of high. Failure of the dam would inundate the baseball field and recreational area immediately below the dam and would pass through a thickly settled residential area. Additional investigations or major modifications are not required.
