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 dam is a 348 foot long, 51 foot high structure, originally designed and constructed as a masonry gravity dam in 1912. Later, an earth embankment was placed against the downstream face of the original masonry dam. The visual inspection indicates the dam is presently in poor condition. The concrete chute spillway is badly weathered, cracked and undermined in several areas. Should the bottom of the chute lift and plug the shallow height chute discharge opening, events could lead to serious undermining and erosion of the earth embankment. Repairs to correct deficiencies with the mechanical elements in the control tower are now being studied by the owner. Effects of reservoir storage would cause the test flood discharge to be 3,600 cfs which would overtop the dam by about 1.6 feet. Spillway capacity at the top of dam is 940 cfs which is 25 percent of the test flood discharge.

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 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: White's Mill Pond dam which was built before 1923 is a 340-foot long earthfill dam with upstream and downstream dry stone masonry walls. The dam has a maximum height of 13 feet and consists of a spillway, low level outlet, an intake toi a plant, and an earth dike. The following deficiencies were observed at the site: severe seepage at several locations along the toe of the dam; downstream stone masonry walls are out of plumb; lack of access to the low level outlet operator; erosion at the low point of the dam crest; bulging of the downstream masonry wall in several locations; stone missing from the upstream face of the spillway, mortar missing from the stone masonry spillway of the dam; heavy growth of brush and trees on the dam crest and on the dike; and an accumulation of debris in the discharge channel. Hydraulic analyses indicate that the spillway (without stoplogs) can discharge 520 cfs, or 76 percent of the test flood outflow before the dam is overtopped. (With the stoplogs, the spillway can discharge 170 cfs or 22 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 1978 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lower Roberts Meadow Reservoir Dam is an earthfill embankment with a maximum height of 22.7 feet and a greatly curved crest, 550 feet long and 10 feet wide. A concrete and stone masonry spillway about 50 feet long, 14 feet high, and a freeboard of 9.3 feet is located near the northeast end of the embankment. Concrete and stone masonry training walls flank the spillay. A concrete low level intake structure with a manully controled slide gate is located about 180 feet west of the spillway. Phase I inspection and evaluation of the Lower Roberts Meadow Reservoir Dam does not indicate conditions which would constitute an immediate hazard to human life or property. Based on engineering judgment and the performance of the earth embankment and the outlet works, the project is considered to be in good condition. The project has a number of deficiencies which, if not remedied, have the potential for developing into hazardous conditions. It is estimated that 23% of the PMF over the combined drainage area could be processed by the combined Middle and Lower Reservoir storage and spillway capacities without overtooping the Lower 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 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Westfield Reservoir Dam is an earthen embankment structure about 350 feet long and 40 feet high. It has an uncontrolled overflow spillway located on the left (east) abutment and a 24-inch diameter cast-iron pipe outlet conduit which passes beneath the dam and which is valve controlled at the outlet end. Based on the visual inspection, the dam is judged to be in air condition. The following deficiencies were observed at the dam: minor but widespread slumping on the downstream slope; an animal burrow on the downstream slope; large trees near both abutments; a soft, wet area along the right bank of the downstream channel; a small sinkhole on the right side of the spillway discharge channel; lack of vegetation on the crest of the dam; inoperable valves on the downstream end of the outlet conduit; and no valve or other means of regulating or shutting off flow at the intake end of the outlet conduit. With the stoplog in place, the spillway capacity of Westfield Reservoir Dam is 707 cfs, which is about 15 percent of the routed test flood outflow of 4670 cfs. With the stoplog removed, the spillway capacity is about 994 cfs, which is about 21 percent of the routed test flood outflow. The test flood would cause the dam to be overtopped by about 3.5 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 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is a buttressed ten foot high, 90 feet wide spillway, with concrete training walls. The visual inspection of the dam indicated it to be in generally fair condition, due to the finding of a seepage boil. The dam has a size classification of small and a hazard classification of low. It is recommended that the owner engage a qualified engineer to investigate the foundation of the right abutment wall and if necessary, design a seepage protection system where a seepage boil was found.

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 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dam is a 940 foot long earth embankment dam with a concrete spillway. It is recommended that the areas of erosion both on the upstream and downstream faces where the abutments and embankment interface be repaired. Surface water in these areas should be redirected to prevent future erosion. The riprap on the upstream face should be extended to the dam's crest. The water exiting from the toe and core wall drains should be directed to a control channel and weir where the flow can be periodically measured. The 20-in capped pipe running beneath the dam to the downstream toe should be uncapped and extended to the lower reservoir. This will prevent the potential of a pressurized pipe (should the outlet gate be left open) from bursting and undermining the dam. Although the spillway can not discharge the test flood without overtopping the dam, the spillway capacity is comparatively large. Because of the hydrologic and safety relationships between this dam and the lower reservoir, it is necessary that future hydrologic studies concerning spillway capacities at either project should simultaneously encompass studies for both projects.

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 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silver Lake Dam is an earthfill embankment about 85 feet long, 12 feet high with a crest width averaging about 30 feet. The project appears to be in fair condition. Since the dam is classified as small in size, with a significant hazard potential, the test flood is one half the PMF. (Author).

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 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whiting Street Pond Dam is an earth-buttresed stone masonry dam, 1900 feet long with a maximum height of about 19 feet. A two level stone masonry and concrete spillway is located about 70 feet from the dam's south abutment. A gatehouse and gate chamber are located at approximately the center of the dam and contain the operating mechanisms for controlling the outflows into the City's Water Supply and to the low level outlet. Discharges from the low level outlet and the spillway converge and flow into an unnamed creek before emptying into the Connecticut River. Phase I inspection and evaluation of Whiting Street Pond Dam does not indicate conditions which would constitute an immediate hazard to human life or property. Based on engineering judgement and the performance of the dam and the outlet works, the project is considered to be in fair condition. The project, however, does have a number of deficiencies which, if not remedied, have the potential for developing into hazardous conditions. The test flood, in accordance with Corps of Engineers guidelines, is the Probable Maximum Flood (PMF). The PMF yields an outflow of 8253 cfs which is greater than the maximum discharge capacity of the spillway of 215 cfs and would result in overtopping of the dam by about 1.4 feet.

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: Lake Whittemore Dam is approximately 300 ft. long. It consists of a small earth embankment approximately 15 ft. high and an ungated concrete ogee spillway weir. The dam is generally in fair to good condition. There are no obvious signs of failure or conditions which would warrant urgent remedial treatment. Hydraulic analyses indicated that the spillway will pass the spillway design flood without overtopping the dam. The spillway design flood selected for this structure was the probable maximum flood. Recommendations for remedial work include clearing of trees and brush, repair of the downstream fieldstone wall and dry-laid stone wall adjacent to the gate valve, and minor earthwork and rip-rap repairs.

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 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ware Industries Man (Upper) Dam consists of a main spillway 115 ft. long and approximately 34 ft. high, a spillway extension 50 ft. long and 4 ft. high, a concrete emergency spillway, a gate house with control works to a canal, and a 115 ft. long overflow weir from the canal. Based on a visual examination of the structure, the project is in good to fair condition. There was no evidence of structural failure or other conditions which would warrant urgent remedial action. The PMF outflow of 109,200 cfs would overtop the dam by 11.25 ft. With the water level at the top of dam, the spillway system can pass 7980 cfs which is 7.3 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 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chicopee Reservoir Dam is a 545-foot long, 47-foot high earth embankment dam constructed circa 1926. The spillway is a 44-foot long ogee crest which si located at the right abutment of the dam and has a crest elevation (El) 168.0. The outlet conduits are a 24-inch cast-iron former water supply line and a 30-inch cast-iron blowoff. The following deficiencies were observed at the site: high degree of erosion of the principal spillway chute structure and outlet training walls; erosion gullies on the right abutment above the dam crest; brush growth on the downstream slope of the embankment; and seepage from the left abutment downstream of the dam. Generally, the dam is in fiar condition. The adopted spillway Test Flood is equal to the Probable Maximum Flood which yields a peak test flood inflow of 7565 cfs. Hydraulic analyses indicate that the spillway, without flashboards, with the water surface at the top of the dam can discharge 3,950 cfs which is less than the total routed test flood outflow of 6,450 cfs. Thus, the spillway can discharge 60% of the routed test flood outflow.

Phase I Inspection Program written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1980 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Roberts Meadow Upper Reservior Dam is a cut stone masonry and earth gravity dam having a hydraulic height of 35 feet, length of 305 feet including a 150 foot long dike. The stone masonry section is approximately 65 feet wide, is slightly arched in an upstream ddirection, has a crest width of 4.5 feet and serves as the spillway. The 1/2 PMF test flood inflow for Roberts Meadow Upper Reservior Dam, having a drainage area of 8.8 square miles was determined to be 7480 cfs which would overtop the dam by about 3.4 ft. The spillway capacity at the top of the dam is 1500 cfs which is 20 percent of the test flood discharge. The dam itself is in poor condition. The major concerns are: The large amount of leakage through the stone masonry section which has the potential for freezing and dislocating stone blocks in the face of the dam; internal erosion of the earth embankment at the southerly end of the spillway; brush and tree growth on the embankment sections; and a large unstable mass of bedrock overhanging the downstream channel at the northerly abutment.

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 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wright's Reservoir Dam is approximately 1,000 ft long. It consists of a small earth embankment approximately 14 ft high and an ungated concrete ogee spillway and stilling basin. An 800 ft long dike is present at this facility on the west side of the reservoir. Its maximum height is 12 ft. This facility was constructed in 1964 under the direction of the Corps of Engineers. The dam is generally in good to excellent condition. There are no obvious signs of failure or conditions which would warrant urgent maintenance treatment. Hydraulic analysis indicated that the spillway will pass the spillway test flood without overtopping the dam. The spillway test flood selected for this structure was the probable maximum flood. Recommendations for maintenance work include the clearing of brush and mowing of grass, especially at the west dike and the replacement of the operating handle for the reservoir drain at the outlet works. This work should be performed as part of the regular maintenance of the dam.
