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 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 1978 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dam is a 403 foot long, 42 foot high stone masonry structure. The visual inspection did not disclose any findings that indicated an immediate unsafe condition. The city is in the midst of a program of pressure grouting this dam to stop leaking which was extensive. At the time of the inspection, water was still leaking through the dam but at a much lesser rate than previously reported. The dam's spillway will not pass either the PMF or 1/2 PMF without overtopping the dam, and the spillway is not considered adequate. There is an area of standing water existing below the right abutment of the dam. This area should be cleaned and a surface drainage system installed.

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 1980 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vistron Dam, also known as Pro Brush Dam is a stone masonry gravity dam across the NMill River. The dam has a hydraulic height of 24 feet, 195 feet long, 8 feet wide at the crest with downstream face battered at approximately 1H: 12V. The spillway section of the dam is 140 feet long. The dam is founded on bedrock which is exposed at the southwesterly abutment and along the base of the dam. The dam is presently in good condition with no major problems. The main deficiency noted is the presence of trees growing near the top and out of the side of the dry laid stone retaining wall at the northeasterly abutment. Considering a 20,000 cfs inflow, from the 52 square mile drainage area, and assuming no downstream controls, the dam would be overtopped by approximately 4 feet. Spillway capacity at the top dam is 10,500 cfs which is approximately 4 feet. Spillway capacity at the top of dam is 10,500 cfs which is approximately 52 percent of the 1/2 PMF.

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 Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1981 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lower Glen (Greenfield) Reservoir Dam is a 46-foot high stone masonry dam, spanning the lower portion of a 300-foot deep V-shaped valley. The dam has a crest approximately 95 feet long, a vertical downstream face, a service spillway and an auxiliary spillway. The upstream face of the dam is submerged, and since no construction data are available, the configuration of the upstream side of the dam is unknown. The dam was constructed around 1904 to provide a water supply reservoir for the Town of Greenfield. The reservoir has not been used for water supply purposes for more than 30 years; therefore, the dam now serves no useful purpose. The dam appears to be in poor overall condition. Several joints have opened due to structural movement of the dam as evidenced by a bulge on the downstream face of the dam located just to the east of the center dam pier at mid-height. A great deal of seepage was observed at the location of the bulge and toward the east side groin area. The test flood peak inflow to Lower Glen (Greenfield) Reservoir was computed to be 3,760 cfs. The test flood peak overflow is also 3,760 cfs, with a discharge 4.8 feet over the top of the dam. The service and auxiliary spillways have a combined discharge capacity of 740 cfs, or 20 percent of the routed test flood outflow, just prior to overtopping 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 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 1979 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is a 700 foot, 35 foot high earthfill embankment and a 920 foot long, 15 foot high earth-fill dike a gatehouse with outlet controls and a 10 foot wide concrete arch emergency spillway. With the water lever assumed to spillway crest at time of test flood, spilway discharge of about 30 cfs woudl occur. The reservoir woudl be surcharged to elevation 433, four feet above the spillway crest and two feet below the dam crest. The dam will not be overtopped. The dam is generally in fair condition. Remedial measures consist of removal of all brush and trees from the downstream slope of the main dam and spillway channel and repair of spalled and deteriorated concrete on the emergency spillway.

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: Northfield School Upper Reservoir Dam is a 45-year old earth embankment dam which impounds water for the Northfield - Mt. Hermon School and the Town of East Northfield. The dam is approximately 240 feet long and has a maximum height of about 37 feet. A gatehouse located on the top of the dam provides access to outlet works for the dam. The dam appears to be in fair condition. No obvious signs of settlement or misalignment are evident; however, clear seepage and erosion are apparent at each of the abutments and at the toe of the dam. Lack of a comprehensive operation and maintenance program is also apparent, as evidenced by the presence of small trees and brush on the dam and large trees in close proximity to the dam. In addition, only one of the outlet valves was found to be operable. (Since the date of inspection, the Owner has notified us that all of the valves have been made operable.) The test flood peak inflow to Northfield School Upper Reservoir Dam was computed to be approximately 550 cfs. The corresponding outflow was also 550 cfs and resulted in a 0.5 foot depth of flow over the dam. The spillway (with the flashboards in place) has a discharge capacity of about 180 cfs, or roughly 33 percent of the routed test flood outflow, assuming the reservoir pool is at the top of the dam. Assuming the flashboards are removed or fail prior to overtopping of the dam, the spillway capacity would then be approximately 790 cfs or about 44 percent in excess 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 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 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 1979 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest Park Upper Dam is an earthen embankment approximately 450 feet long and 23 feet high, the 40 foot wide crest carries a park roadway. A semicircular drop inlet spillway located near the center of the dam's upstream face discharges into a culvert beneath the embankment. The gated reservoir drain is incorporated in the spillway weir. The presence of numerous trees and eroded areas on the embankment resulted in the dam being considered only in fair condition. The spillway was determined to be adequate to pass the routed test flood outflow of 1475 cfs with approximately 5.1 feet of freeboard remaining for the dam. The maximum spillway capacity with a flood stage at the top of the dam is 2160 cfs. An investigation is recommended to determine appropriate modifications and repairs for the protection of embankment slopes. Remedial measures to be taken by the Owner include the temporary repair of eroded areas, the cleaning and repair of catch basins and drains and the repair of the spillway and outlet culvert.
