Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1981 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Upper Mill Pond Dam is a stone masonry dam approximately 100 feet long and 15 feet high. The spillway is 92 feet long, 9 feet wide and consists of a masonry broad crested weir. The water level is at the spillway crest and can be lowered by opening the low-level discharge gate which was recently made operable by the Middletown Water Department. In general, the overall condition of the dam is FAIR. The structural stability of the dam is good as evidenced by its vertical, horizontal and lateral alignment. The stone masonry is in good condition although moss and weeds are growing from the joints. The spillway weir and east abutment are in good condition. The west abutment is badly spalled at its base. The discharge gate inlet structure is badly spalled and the bar rack is cluttered with debris. There is some seepage at the east end of the dam where the stone masonry meets the abutment/ledge interface. Vegetation is growing around this area as well. The ledge continues along the downstream channel bank and there is minor seepage. A drainage pipe outlets above the west abutment. There is presently a scour hole at this location. This scour hole has caused the last section of the drainage pipe to collapse into the hole and is undermining the west spillway abutment. At the spillway elevation, the water surface area and storage capacity is 5 acres and 31 acre-feet respectively. The spillway capacity when the water level in the pond is at the top of the dam is 250 cfs. The test flood will overtop the dam by 1.8 feet.

Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1981 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mill Pond Dam is an earth-covered, irregular natural rock formation 600 ft. long, with a top width varying from 10 to 20 ft. and a maximum height of 19 ft. The outlet for the dam is a natural rock weir spillway approximately 35 ft. wide, which is overpassed by a footbridge. The crest of the spillway is about 3 ft. below the lowest point on the dam crest. Based on visual inspection, the Mill Pond Dam is judged to be in good condition; however, during the inspection, there was a light snow cover of approximately 2 inches which may have obscured problems, such as erosion or seepage. A test flood of a 100 year frequency was selected in accordance with the Corps of Engineers' Guidelines. The calculated test flood inflow of 1,000 cfs results in a routed outflow of 990 cfs. With the water level at the top of the dam the spillway capacity is 575 cfs which is 58% of the outflow flood. The storage capacity of the Mill Pond is 52 ac.-ft. at the top 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 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Papermill Pond Dam is a 573 ft. long composite rubble masonry, concrete, and earth embankment dam consisting of a 124.5 ft. long gravity masonry overflow section, and 84 ft. long earth embankment to the right of the overflow section and a 365 ft. long earth embankment to the left of the overflow section. About 160 ft. of the upstream face of the left embankment is paved with concrete. It is a run-of-the-river dam which is used for storing process water for a paper mill located upstream on the left bank of the river. In the left embankment there is an intake which controlled flows through a conduit to a turbine facility in a mill building located immediately downstream of the dam. The turbine has been abandoned and the mill building is in the process of being razed. The spillway for the dam is equipped with 2.3 ft. high permanent wooden flashboards. The dam is judged to be in generally good condition, but is rated as in fair condition owing to the absence of a dewatering facility. There is brush growth on both embankments. Mortar is missing from the joints of the rubble masonry section of the spillway. There is a crack in the concrete apron on the left embankment and the construction joints of the apron have opened up. Minor erosion has taken place on the downstream slope of the left embankment. The spillway can pass 7,750 cfs or about 72 percent of the routed test flood outflow without overtopping the right embankment.

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 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mill Pond Dam is 220 feet in length, with a maximum height of 18 feet. The upstream face of dam is a vertical mortared stone masonry wall partially replaced in areas with concrete. The downstream face of the dam is a concrete wall approximately 12 feet in height and 4 feet wide. The remains of a factory foundation occupy the irregular shaped dam crest, 30 to 60 feet wide. The composition of the fill material is unknown. The spillway is 68 feet in length extending from the left abutment. Based on the visual inspection, the Mill Pond Dam appears to be in fair condition. Some settlement and cracking of the floor slab at the crest of the dam has occurred. The downstream concrete face appears to be in good condition. Downstream from the concrete portion of the dam a nearly level grassed area was observed. The grassed area indicated no visible seepage and was in generally good condition. The visible face of the spillway is in fair condition. A portion of the right spillway training wall had collapsed for a distance of approximately 18 feet. Most of the stone masonry blocks have been removed in this section and the embankment has been eroded back for a distance of approximately 8 feet. A cast iron drainage pipe is located adjacent to the end of the concrete training wall in this collapsed section. Other portions of the existing wall have been undermined causing masonry blocks to be removed. The outlet structure service gates have recently been replaced and are in good condition. The capacity of the spillway is inadequate to pass the 1/2 PMF test flood outflow of 8,070 CFS and would overtop the dam by 4.9 feet. The spillway is adequate to pass 15 percent of the test flood.

Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1981 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Paper Goods Pond Dam is a concrete and masonry structure. It is approximately 70 feet long, 30 feet high and has an average top width of 4 feet. The Paper Goods Pond Dam was probably constructed in 1920 with subsequent improvements in 1939. The present owner and operator of the dam is Sherwood Industries, Inc., which uses the pond for industrial water supply. Based on visual inspection and past operational performance, the dam is judged to be in FAIR condition. Seepage was noted through the southwest abutment and along the southern downstream channel wall. The 10 inch supply main presently has no control at the dam. The test flood for this dam is 1/2 the Probable Maximum Flood (PMF). The test flood has an inflow equal to 6415 cfs and an outflow discharge equal to 6400 cfs with a stillwater elevation of 125.0 which will overtop the dam by 5.5 feet. The maximum outflow capacity of the spillway with the water surface at the top of the dam is 1190 cfs, which is 19 percent of the test flood outflow.

Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1981 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rogers Pond Dam is a 231 foot long earth and vertical stone masonry dam with a maximum height of 9 feet. There is a 50 foot long concrete spillway near the center of the dam. The width of the dam varies from a minimum of 6 feet at the right spillway edge to 21 feet at the left abutment. The purpose of this dam is primarily recreational. The visual inspection of Rogers Pond Dam indicated that the dam is in fair condition. The inspection revealed that portions of the upstream masonry wall have been displaced at several locations. Numerous trees are growing on the left upstream embankment. Seepage was noted along the stone wall on both sides of the spillway and the ground was wet and soggy 25 feet downstream of the left side of the dam, and a large depression was observed just downstream of the wall along the right side of the dam. The storage at top of dam is 60 acre-feet. The spillway will discharge 500 cfs or 42% of the test flood with the pool level at the top of the dam. The peak test flood inflow is 1195 cfs, with a peak test flood outflow of 1140 cfs, which will overtop the dam by 0.6 feet.

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 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam consists of a 400 foot long concrete spillway across the Farmington River with an adjacent hydroelectric generating powerhouse, and a 100 foot long butressed concrete transition dam spanning from the 70 foot long powerhouse to a 1050 foot long earth dike running along the pond shoreline. There are two low level sluices through the spillway section which are operated by hydraulic lifts in a chamber above the sluices. The sluices have an inlet elevation approximately 44.5 feet below the crest of the spillway. The 4 inlets to the turbines are approximately 34.5 feet below the crest of the spillway; the discharge flows to a tailrace channel cut into bedrock to the left of the spillway discharge channel. A fish ladder with an inlet about 1.5 feet below the spillway crest also discharges into the tailrace channel. All inlet gates are well maintained and operable. Based upon the visual inspection and past performance, the dam is judged to be in fair condition. No evidence of instability was observed in the dam or its appurtenances. The condition of the earth dike is good, however there are areas requiring attention. Based upon our hydraulics computations, the spillway capacity is 101,000 (cfs), which is equivalent to 51% of the routed Test Flood outflow.

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 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is located on a tributary of the Connecticut River on the town line of Bolton and Vernon, Tolland County, Connecticut. It is an earthfill structure approximately 625 ft. long with a maximum depth at its center of 26 ft. The crest width varies from 12 to 15 feet. A vertical granite masonry wall extends from the downstream side of the crest to the bed of Lydall Brook below. The visable part of the upstream embankment has a 1 on 2 to 1 on 3 slope with a riprap face. The downstream embankment consists of cobbles and boulders piled against the face of the masonry wall on an approximate 1 on 1.5 slope. The dam is in generally good condition. It appears to be structurally stable at the present time under normal conditions. Based on its small size and high hazard classification in accordance with the Corps' guidelines, the test flood is 1/2 the PMF. The spillway will pass only about 44 percent of the test flood and is considered inadequate. Recommendations to improve dam safety are: (1) Increase spillway capacity; (2) Replace 6-in. discharge pipe and relocate valve; (3) Add riprap near the center on the downstream side; (4) Divert spillway discharge away from the toe 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 1978 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Powder Mill Pond Dam is located on the Ware River approximately one mile upstream of South Barre, Massachusetts. The dam, reconstructed in 1908 to generate electric power for the Barre Wool Combing Company, consists of an upgated concrete spillway approximately 125 ft. long and 20 ft. high, a short emergency spillway and an outlet canal with two inoperative timber gates. The dam was extensively modified during the 1930's. Based on a visual examination of the structure, the facility is in fair to poor condition. Nevertheless, there was no evidence of structural failure or other conditions which would warrant urgent remedial treatment. Based on size and hazard classifications in accordance with Corps of Engineers guidelines, the test flood for this dam is the Probable Maximum Flood (PMF). The PMF outflow of 48,160 cfs would overtop the dam by 5.15 ft. With the water level at top of dam, the main and emergency spillways can pass 17,940 cfs which is 37 percent of the test flood.

Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1981 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Pin Shop Pond Dam consists of an earth embankment with a 100 fokot long stone masonry overflow spillway located at the left end of the dam. Teh dam has a total length of 400 feet and a miximum height of 23 feet. The outlet works located to the left of the spillway consistk of an intake sluice gate which discharges into a stone masonry and concrete structure. A 16-inch gate valve drains the structure and discharges downstream of the spillway, A conduit to a downstream industrial complex is plugged with concrete. Based on the visual inspection, the dam is judged to be in poor condition. The future integrity of the dam can be affected by the lack of slope protection on the upstream slope, and continued erosion of the upstream and downstream slopes; trees on the embankment; continued undermining of the spillway apron; vegetation growing in open joints of the stone masonry training walls; the poor condition of the outlet works; and indagequate spillway capacity. The spillway has a capacity of 3,200 cfs and is capable of discharging 34 percent of the Test Flood outflow.

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 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Merriman Pond Dam consists of an earth embankment with a maximum height of 16 feet, a top width that varies from 30 to 80 feet, and an overall length of 500 feet, including a 12.5 foot long overflow spillway located approximately 150 feet from the right end of the dam. A paved road extends the entire length of the dam with a steel beam and concrete bridge crossing the spillway discharge channel. The outlet works consist of an 8-inch low level outlet or blowoff located to the left of the spillway and controlled by a downstream valve. The dam impounds Merriman Pond which is used as the water supply for turf irrigation of an adjacent golf course. Based on the visual inspection, the dam is judged to be in poor condition. Features that could affect the future integrity of the dam are continued erosion of the upstream and downstream slopes, seepage through the embankment, the presence of trees, stumps and brush on the downstream slope and deterioration of the spillway wing walls. The Test Flood inflow of 680 cfs results in a routed outflow of 345 cfs that overtops the dam by 0.1 feet. The spillway capacity with the water level at the top of the dam is 330 cfs and is equal to 96 percent of the Test Flood routed outflow.

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 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Hockanum River Dam consists of a 28 foot long earth embankment with vertical stone masonry walls on the upstream and downstream faces. A concrete spillway 80 feet in the length extends from the earth embankment to the left abutment. The maximum height of the dam is 37 feet. Based on the visual inspection the Hockanum River Dam appears to be in fair condition. Several trees are growing on the crest and upstream face of the dam. Seepage was observed on the downstream face near the left end of the earth embankment section. There is a hole in the stone masonry about 7 ft. down from the crest of the dam. The visible portion of the spillway and training walls were in poor condition with the concrete having a rough surface due to erosion and spalling. The test flood would overtop the dam by 3.1 feet. The spillway is adequate to pass 38 percent of the test flood outflow without overtopping the dam.
