Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1980 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winnekeag Lake Dam is a 260-foot long dry-stone masonry and earth dam built prior to 1878. The dam has a maximum height of 21 feet and consists of a spillway and separate outlet structure. The downstream slope of the dam is a vertical dry-stone masonry wall. Generally the dam is in fair condition. The following deficiencies were observed at the site: bulging of downstream stone wall; seepage discharging from the stone culvert low-level outlet; seepage downstream of the toe of the dam; several sinkholes on the crest of the dam adjacent to the downstream stone wall; animal burrows on the crest of the dam; voids between the stones on the downstream wall; erosion of the crest adjacent to the spillway right training wall; riprap missing from the upstream face of the dam; cracked concrete at the upstream end of the spillway left training wall; and an accumulation of debris in the low level outlet culvert and spillway discharge channel. The test flood would overtop the dam by 0.4 feet. Hydraulic analyses indicate that the spillway (without stoplogs) can discharge 1530 cfs, or 83 percent of the test flood outflow before the dam is overtopped. With stoplogs (1.4 feet high) the spillway can discharge 1,150 cfs or 47 percent of the test flood outflow before the dam is overtopped.

Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1979 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stodge Meadow Pond Dam is formed by an approximately 250 ft. long earth embankment which has a maximum height of 15 ft. A conduit spillway controlled by an overflow weir with stoplogs and a gated outlet conduit are both appurtenant to the dam. The dam is over 100 years old, except for the conduit spillway, which was constructed in 1977. The pond has a maximum storage capacity of about 900 acre-ft. and is used for recreational purposes by the surrounding group of property owners, who collectively own the pond and dam. The dam is in good condition, based on a visual examination of the structure. Although some deficiencies were noted, there was no evidence of settlement, lateral movement or other signs of structural failure or other conditions which would warrant urgent remedial action. With the water level at the top of the dam, the ungated spillway capacity is 325 cfs. Hydraulic analyses indicate that the test flood outflow of 240 cfs (inflow 605 cfs or 2,600 csm) can be passed with a freeboard of 0.4 ft. and an unused surcharge-storage of 210 acre-ft. remaining.

Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1978 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam appears to be in good condition, The 'V' spillway is 90 ft. long with effective abutments of about 10 ft. on either end. The dam is about 15 ft. high at the abutments. Although the dam is in the small size category the hazard potential is extremely high and thus the situation was analyzed using the full probable maximum flood. A failure of the dam would overflow the left bank immediately below the dam, flood nearby buildings and streets.

Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1978 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam comprises a concrete ogee spillway section with earthfill abutments behind concrete wing walls. The total height of the dam is about 20 ft. It is small in size with a high hazard classification. The potential hazard to property, and possible human life, is the proximity of the industrial complex to the reservoir and the inadequacy of the channel through the complex to convey high flows, be they the result of high and continued precipitation or a failure of the dam.

Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1979 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bailey Pond Dam, Amesbury, Mass., is a 180 foot long earth embankment with concrete walls forming a portion of the upstream face of the dam and the approach channel to the spillway. The height of the dam is 15 ft. which is the height of the inlet chamber below the spillway. The dam and spillway are generally in fair condition. A test flood equal to 1/4 the PMF was selected.

Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1979 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chaffin Pond Dam is actually a section of roadway embankment approximately 135 ft. long, 11 ft. high and with a minimum width of 100 ft. Three submerged culvert outlets pass through the dam between upstream and downstream headwalls, allowing the water level to be the same on both sides of the dam. The control entrance to the assumed 30-in. diameter outlet on the left side has slots for stoplogs; however, none are in place. The control for a 4-ft. box culvert in the center is an open wood gate. The third outlet culvert is also gated but apparently blocked. Water from Chaffin Pond flows to outlet works at a second pond downstream from the dam where water is drawn for hydraulic research purposes. The dam is in poor condition, based on a visual examination of the structure. The headwalls have experienced major structural failures and the potential for a collapse of the upstream headwall with possible obstruction of flow to the outlet does exist. Hydraulic analyses indicate that the test flood would surcharge the pond by 680 acre-ft. and raise the pond level to about 4.2 ft. below the top of the dam. Therefore, no overtopping would be expected.

Book excerpt: The dam is a 470 ft. long earthfill dam with a maximum height of 14 ft. There are deficiencies which must be corrected to assure the continued performance of the dam. Generally the dam is in poor condition. It is small in size with a hazard potential of high. (Author).

Book excerpt: The 410 ft. by 700 ft., stone lined reservoir which is located near the top of Tower Hill is almost entirely surrounded by an earthfill embankment. The embankment is 1870 ft. long and has a maximum height of 29 ft. There are deficiencies which must be corrected to assure the continued performance of the reservoir and embankment. Generally, both are in good condition.

Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1984 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is a 350 foot long, 24 foot high, gravity, earth embankment structure with a 20 foot long masonry spillway and two sealed outlets. The visual inspection indicated the dam to be in generally fair condition. The deficiencies noted during the inspection include the presence of roots of trees growing on the upstream and downstream faces which could cause internal erosion of the dam; the spillway gates have not been operated in several years; and there is no drawdown facility. Considering the reservoir to be at its normal elevation of 183.5, the spillway can pass 485 cfs or 10 percent of the outflow, resulting in the dam being overtrapped by about 3.3 feet. Raising and or removal of gates will increase discharge capacity to 25 percent.

The dam is in good condition, based on a visual examination of the structure. Although some deficiencies were noted, there was no evidence of settlement, lateral movement or other signs of structural failure or other conditions which would warrant urgent remedial treatment. Based on size and hazard classification in accordance with Corps of Engineers guidelines, the test flood for this dam is the 100-year flood. With the water level at top of dam, the spillway has a capacity of 60 cfs. Hydraulic analyses indicate the test flood outflow of 22 cfs (17.7 csm) can be passed with a freeboard of 0.76 ft. remaining.
