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: The dam is a 205 foot long concrete gravity structure keyed into rock at both abutments. The top of the dam is typically 5.5 feet wide and approximately 25 feet above the bed of the Mattabesset River. The upstream face of the dam by visual inspection is vertical, while the downstream face is battered on an inclination of approximately 2 horizontal to 1 vertical based upon field measurements. The spillway is a concrete, broad crested compound weir of trapezoidal cross-section with a shallow bucket dissipator apron. The spillway crest is 3.0 feet below the top of the dam. There are two low level gates on the upstream face of the dam. One gate feeds the 42 inch cast iron low level outlet, and is operable. The other gate feeds a pipeline which was used to provide water to the downstream railroad line. This gate is inoperable and the present existence and condition of the pipeline is uncertain. There are three residential structures and a storage building located immediately downstream of the dam. Based upon the visual inspection at the site and past performance history, the dam appears to be in fair condition. No evidence of instability in the dam was observed. Downstream of the dam approximately 70 feet, the left channel wall is collapsed and at this point is in poor condition. There are some other areas requiring attention as well, in the form of minor maintenance or monitoring. Based upon our hydraulics computations, the spillway capacity is 1560 cubic feet per second (cfs), which is equivalent to 18% 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 1980 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam and dike are judged to be in poor condition. The crest of the dam is in poor condition with large vehicle ruts. A deep hole on the crest was observed in the vicinity of the service bridge. No movement or settlement of the crest was indicated and the vertical and horizontal alignment was generally good. The riprap on the upstream face has many gaps leaving the embankment unprotected. Numerous tree stumps were observed on the upstream face. The slopes are extensively overgrown with brush, grass and large trees. The downstream slope has an undulating surface in many locations. A considerable wet area is located along the downstream toe. Numerous small streams were noted carrying water from seeps eminating on the downstream face. The spillway is in very poor condition. The dike's upstream face is unprotected. Extensive vegetation and stumps exist on the upstream and downstream slopes. A large erosion gully approximately four feet deep has formed on the downstream slope. Seepage is evident along the majority of the downstream toe. A small scarp was observed along the downstream toe probably due to continued seepage. A small boil was observed approximately 20 feet downstream of the toe. The capacity of the spillway is inadequate to pass the one half PMF test flood outflow of 3206 CFS without overtopping the dam and dike. The test flood would overtop the dam by about 0.2 feet. The spillway is adequate to pass about 84 percent of the test flood outflow without overtopping the dam and dike.

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 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: The drainage area is 2.0 square miles and the reservoir has 825 acre-feet of storage capacity. The assessment of the dam is based on a visual inspection, past operational performance and hydraulic/hydrologic computations. The dam is judged to be in FAIR condition with several areas that require attention. These areas include seepage through the dam in the vicinity of the low-level discharge pipes and wet spots along the toe of the dam, vegetation on the embankments as well as along the toe of the dam and the inoperable status of the low-level discharge pipe. The test flood outflow will not overtop the dam and will leave 0.4 feet of freeboard.

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 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hallmere Reservoir Dam is an earthfill embankment about 570 ft. long and 45 ft. high. It has a concrete core and a riprap covered upstream face. It was constructed in 1896-97 for purposes of water supply. A 30 ft. wide masonry waste-way with s ill and flashboards serves as the spillway. The only regulated outlet is a 20 in. dia. concrete pipe. The maximum storage capacity of the reservoir to top of dam is about 585 acre ft. and the drainage area is about 1 sq. mi. The dam appears to be in fair condition. Brush and tree growth has begun to intrude on the slopes and crest of the embankment. Seepage was noted at the downstream toe of the dam. Animal burrows and missing riprap was apparent on the upstream slope of the embankment. The test flood inflow is 3200 cfs. The routed test flood outflow (2,900 cfs) overtops the dam by 0.7 ft. The spillway is adequate to pass an outflow corresponding to about 51 percent of the routed test flood outflow but the spillway and discharge channel walls would be overtopped by about 5 ft.

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 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 140 foot long dam is an earth embankment, the top of which, at elevation 154.5, is approximately 15 feet above the streambed of Belcher Brook. A drop inlet at a flow line elevation about 4.5 feet below the top of the dam, is the spillway facility. A wooden gate extending the full 7.5 foot depth of the structure is the low level outlet, however it is apparently stuck in a closed position. The inlet structure feeds an arched brick culvert which has an estimated chord length of 7 feet and an effective depth of approximately 3 feet, due to heavy siltation. A recent partial collapse of the brick culvert where it abuts the downstream low-level outlet headwall caused partial blockage of the culvert as well as an approximately six foot wide cavity and sloughing to the crest of the dam on the downstream slope. Based on the visual inspection at the site and past performance, the dam is judged to be in very poor condition. Evidence of instability was noted in the form of a collapse of the outlet conduit and a subsequent failure of the downstream slope of the dam. There are other areas requiring attention as well. Based upon the hydraulics computations, the spillway capacity is 180 cfs to the top of the dam, which is equivalent to 72% 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 1980 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Upper Pond Dam is an earth embankment dam with a maximum height of 17 feet and a length of 390 feet. The dam embankment left of the spillway is approximately 10 feet in width, with 2 horizontal to 1 vertical upstream and downstream embankment slopes. The centrally located spillway is 72 feet in length and is a stone masonry structure. Stone masonry training walls approximately 5 feet in height are located at each side of the spillway. The outlet works consist of a concrete gate structure and an outlet channel. Based on the visual inspection, the Upper Pond Dam appears to be in poor condition. There was no movement or settlement of the crest observed. The horizontal alignment is good. The top of the outlet gate structure, however, is lower than the embankment crest. Some erosion was noted at the abutments, adjacent to the spillway section and adjacent to the outlet works. Trespassing on the slopes was not significant. Erosion scarps on the upstream slope extending 1-2 feet above waterline were noted. Several areas of broad shallow erosion on the upstream slope and upstream side of abutments were observed. Brush and many large trees (up to 2.5-ft.-dia.) with extensive root systems were noted on the slopes and crest of the dam. Standing water was observed in an area 35 feet downstream of the toe on the right side of the dam. The capacity of the spillway is inadequate to pass the 1/2 PMF test flood outflow of 5,195 CFS and would overtop the dam by about 0.9 feet. The spillway can pass about 33 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 1979 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: This facility is a 400 foot long concrete gravity dam across the Farmington River consisting of a 40 foot long right abutment housing three low level sluicee gates, a 300 foot long spillway, and a 60 foot long left abutment with a brick gatehouse housing six intermediate level sluice gates. The hydraulic height of the dam is approximately 33 feet. The six sluices in the left abutment discharge to a 640 foot long canal feeding a powerhouse at the end of the canal, which is not presently in use. The canal was excavated in the left riverbank and is lined with a concrete wall on the right side and a masonry wall on the left side. Based upon the visual inspection at the site, existing data, and past performance, the dam is judged to be in fair condition. No evidence of immediate structural instability of the dam or its appurtenances was observed, however, there is spalling of concrete on the abutments, canal walls, powerhouse bulkhead, and most probably on the crest and downstream face of the spillway and there is a seep at the juncture of the right abutment of the dam with the adjacent bedrock riverbank. The spillway capacity to the top of the dam is 33,000 cfs, which is equivalent to approximately 40% 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 1981 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wintonbury Dam consists of an earth embankment, approximately 1,625 ft. long, with a top width of 12 ft. and a maximum height of 23 ft. The principal spillway consists of a two stage reinforced concrete intake riser discharging through a 30 inch, 145 ft. long reinforced concrete pipe under the dam embankment. The emergency spillway is a trapezoidal grassed channel 110 ft. wide at the control section with its crest 4.5 ft. below the top of the dam. Based on visual inspection and review of available plans and reports, Wintonbury Dam is judged to be in good condition. Some features found existing that could affect the stability of the dam are wheel ruts on the crests and slopes, damage by burrowing animals, and sloughing and eroding of the east and west slopes of the downstream pool area. The dam is a flood control project and therefore the reservoir is dry except during periods of heavy rainfall. With the reservoir dry, the inspection could not reveal seepage conditions. The spillway is capable of passing 300 per cent of the routed test flood outflow without overtopping the dam. The storage capacity to the top of the dam is 1,750 ac.-ft. and up to the test flood level is 1,240 ac.-ft.

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 1981 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bloomfield Dam consists of an earth embankment approximately 4,550 ft. long, with a top width of 12 ft. and a maximum height of 29 ft. In addition, there is a 750 ft. long dike 10 ft. high with a 10 ft. top width. The two outlets for the dam are the unregulated principal spillway and emergency spillway. The principal is a drop inlet structure consisting of a two stage reinforced concrete intake riser discharging through a 36 diameter, 177 ft. long reinforced concrete pipe under the dam embankment. The emergency spillway is a trapezoidal grassed channel, 175 ft. wide at the control section with its crest 5.0 ft. below the top of the dam. Based on visual inspection and review of available plans and reports, the Bloomfield Dam is judged to be in good condition. Some features found existing that could affect the stability of the dam are, wheel ruts and erosion gullies along the crest and slopes and damage by burrowing animals. The dam is a flood control project and, therefore, the reservoir is dry except during periods of heavy rainfall. With the reservoir dry, the inspection could not reveal seepage conditions. The spillway is capable of passing 278% of the routed test flood outflow without overtopping the dam.

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 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: This flood control project consists of a dam and dike which are earth embankments at 3H:1V with good grass cover and a top width of 12 feet. The dam is approximately 3060 feet long and 31 feet high. The dike is approximately 475 feet long and 28 feet high. The principal spillway consists of a reinforced concrete riser, a 30 inch RCP through the dam and a reinforces concrete impact basin. The emergency spillway is a 130 foot wide grassed earth channel at the eastern end of the dam. The reservoir is normally empty except for a small sediment pool. Based on the visual inspection, review of design information, and past operational performance, the dam and dike are judged to be in GOOD condition. There is some erosion due to vehicle trespass and animal burrows were noted in the embankments. The maximum outflow capacity of the spillways with the water level at the top of the dam is 3580 cfs, which is 185 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 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bushy Hill Pond Dam is an earth embankment structure 265 feet in length with a maximum height of 29 feet. A stone spillway 20 feet in length is located at the right abutment of the dam. The upstream face of the dam is a vertical concrete wall. The dam crest and downstream embankment are grassed. The spillway is located at the right abutment and is 20 feet in length. A 12 inch blow-off pipe provides a low level outlet. Based on the visual inspection, Bushy Hill Pond Dam and its appurtenances are judged to be in poor condition. The crest of the dam appears to dip toward the upstream face. The vertical alignment is good. The face appears to bow slightly upstream and the concrete wall is cracked at many locations. The downstream slope is uneven and erosion has occurred along the toe. Large boulders were observed at the intersection of dam and spillway training wall on the left side of the spillway. Seepage was noted along the toe of the downstream slope. The stone masonry overflow spillway section has open joints; however, no movement or seepage was observed. The spillway discharge channel is in general good condition. Some sloughing of the channel embankment (right side) was noted about 20 feet below the spillway. A 12-inch diameter low level blow-off was operated during the site visit. The test flood would overtop the dam by 1.4 feet. The spillway capacity without overtopping is 140 CFS which is about 9 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 1978 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crescent Lake Dam is about 600 ft. long, 12 ft. high and has a crest width of about 15 ft. It is an earthen embankment with a downstream slope of about 2 to 1 and a variable upstream slope. There is no orthodox spillway structure, but an unlined channel in the reservoir bank near the right abutment serves as a wasteway for reservoir spills. An outlet canal takes off from the reservoir about 600 ft. upstream from the left abutment, which has a concrete headwall incorporating a 38 in. wide notch with stoplog slots. There appears to be no other outlet structure. Maximum storage capacity is about 335 acre-feet. Crescent Lake, used now for recreational purposes, is less than a mile long, has a surface of about 36 acres and a drainage area of about two square miles. The dam is in fair condition. There is some seepage along the downstream toe of the embankment, which has large mature trees growing on it. The lack of any outlet gate precludes drainage the lake without breaching the dam. The test flood would not overtop the dam but would reach within 1/2 ft. of the crest and overtop areas of reservoir bank adjacent to both left and right abutments, which appear to be as much as 2 ft. lower than the crest of the dam. It appears that the valley area east of the Penn Central Railroad track which is just downstream from the dam would absorb outflows up to the test flood magnitude without major consequences to downstream interests.

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 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wasel Reservoir Dam is a zoned earth embankment about 350 ft. long with a maximum height of about 80 ft. and a crest width of 20 ft. It is located at the north end of the reservoir. The dike at the south end is of similar construction, about 1,400 ft. long, with a maximum height of 50 ft. The spillway is located at the left abutment of the main dam, consisting of a 10 ft. wide channel cut through the rocket around the left end of the dam, and a 2 st. high concrete control dia. with its crest 8 ft. below the crest of the dam. The outlet tower near the left abutment has three 30-in. dia. inlets at varying levels and a 30-in. dia. outlet leading to the filter plant below Shuttle Meadows Reservoir. Wasel Reservoir is utilized as a water storage facility by the City of New Britain. It is about 4,000 ft. long and has a surface at normal storage of 103 acres. The drainage area is 0.38 sq. mile and the maximum storage at top of dam is 3,600 acre-ft. The dam appears to be in good condition. The spillway is adequate to pass the full PMF test flood without overtopping the dam. The south dike also appears to be in good condition. Seepage at the downstream toe of the dike was noted, as was a wet area of undetermined cause downstream of the dike at the right abutment.

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.
