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.

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 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is generally comprised of a 401-foot long, 10 to 28 foot high main spillway, a head gate building, an overflow canal spillway and a canal leading to two 8 foot diameter penstocks used in electrical power generation. There are two inoperable gates located in the main dam. The dam is normally operated with two feet of flashboards above the spillway crest. The visual inspection did not disclose any findings that indicate an immediate unsafe condition. The 1 /2 PMF test flood used will produce an inflow/outflow of 70,830 cfs. The dam is a run-of-the-river type and the spillway crest would be overtopped by about 14 feet. The spillway has a capacity of 29,500 cfs (42 percent of 1/2 PMF outlfow) at elevation 166.6, top of non-overflow section. The non-overflow section is overtopped by about six feet. This flow would not overtop the upstream training walls which are at elevation 174.0. The overall condition of the dam is considered fair due to the lack of adequate draw down capacity. Remedial measures consist of removing vegetation from the downstream face of the dam, further observation of seepage at the right abutment, repair the wooden crest cover, and develop a formal warning system to warn downstream areas in case of an emergency.

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 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is a stone masonry gravity dam having a hydraulic height of 26 ft., 100 ft. long, 9 ft. wide at the crest, and a vertical downstream face. The dam is in poor condition and it appears that maintenance of the structure has been neglected. It is small in size with a hazard potential of high. Assuming that the flood plain of the Deerfield River is not already inundated, a major breach of the dam would cause flooding of 2 to 3 feet in the area near the downstream elementary school.

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 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: West Parish Filter No. 3 Dam is an earthen embankment structure 37.5 feet high and 800 feet long. A side-channel spillway is located at the right abutment. It has a concrete overflow section which is 23.4 feet long. Outlet piping passes beneath the embankment and connects directly to the water treatment plant which serves the City of Springfield, Mass. The dam is situated on a very small (0.07 sq. mi) drainage area, and serves as offstream storage and as a sedimentation basin for water which is piped from other dams. Based on the visual inspection, the dam is judged to be in fair condition. The following deficiencies were observed at the dam: a soft, wet area near the downstream toe; a row of evergreen trees along the downstream toe with some roots penetrating the embankment; rodent holes on the downstream slope; wheel tracks on the crest of the dam; misaligned riprap and loose rock and trees overhanging the spillway; low areas on the top of the dam; and no means of controlling flow at the upstream end of the outlet conduit. The spillway capacity is about 335 percent of the routed test flood outflow of 142 cfs. During the test flood, the freeboard would be 1.9 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 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 1978 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Springfield Water Works Intake dam is an approximate 295 foot long concrete masonry structure spanning a gorge in the Little River. This dam is built on a 180 foot radius and appears to be functioning as an arch. The visual inspection of this dam did not disclose any findings that indicate an unsafe condition. The spillway for this dam is able to pass a 1/2 PMF flow from its own drainage area of 3.15 s.m. It must be noted however, that the Cobble Mountain Reservoir, some 2.75 miles upstream, could affect the flow at this site. Should the Cobble Mountain Reservoir be full and overflowing its spillway at a time of flooding conditions, the flow at this site would change significantly. It is recommended that the owner have repairs made to certain spalled areas of the intake structure and wasteway.
