This book was released on 1979 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dams are in fair condition, due to the potential overtopping of the dams during the occurrence of the test flood and the reported overtopping of the dams during prior floods. There is some eroding of concrete joints in the dam, deteriorated concrete on appurtenant structures and observed seepage both from the joints in the concrete and from the embankments. The east dike is heavily overgrown with brush and young trees. Hydraulic analysis indicates that the test flood stage would be at elevation 240.3 which is approximately 4.3 feet above the top of the right embankment. Approximately 95 percent of the test flood would pass over the 60 foot dam, 29 foot dam and the small dam spillways. The remaining flow would be over the right embankment between the screen house and the mill building.

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).

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.

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.

This book was released on 1978 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: The South Barre Mill Pond dam is a small dam consisting of two adjacent concrete ogee spillways, a short earth embankment on the right side and an outlet works to a penstock at the left abutment. The present dam, constructed about 1904, was extensively damaged in the floods of 1936 and 1938 and has been reconstructed on several occasions, the latest work in 1944. The dam is in fair to good condition. There are no obvious signs of failure or conditions which would warrant urgent remedial treatment. Hydraulic analyses indicate that the spillway will not pass one-half the probable maximum flood and the spillway is considered inadequate, Recommendations for remedial work include repair of concrete at the left training wall and right spillway weir and restoration of gates to good operating condition. Additional investigation of the right spillway weir is recommended, since no data are available concerning this portion of the structure.

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.

This book was released on 1980 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is comprised of a 1,300 foot long, 49.5 foot high earth fill embankment having a concrete core wall. The reservoir is a pump storage facility, having no inlet stream or spillway. Between the design high water level, elevation 144, and the top of dam, elevation 147.5, there is 221 acre-feet of available storage. This capacity is sufficient to store all the runoff, 203 acre-feet, from the drainage area. There will be no test flood outflow. The dam will not be overtopped. The following remedial measures should be instituted by the Owner: grass and brush on the dam should be cut and maintained; animal burrows should be filled-in and prevented from reoccuring; trespassing on the dam should be prevented; a formal warning system for the downstream impact area should be developed and the dam should be inspected once every year by a qualified registered professional engineer.

This book was released on 1979 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dam generally consists of a 190 foot masonry spillway, an earthfill embankment and 2 outlet pipes. The dam was designed in 1955 by Stone and Webster Engineering Corporation to replace an earlier dam, which was damaged by the flood of that year. Construction which utilized portions of the original structure was completed in 1957. The visual inspection showed the dam to be in good condition. However, water passing over the spillway limited the inspection of the spillway. The spillway is capable of passing 96% of the test flood outflow. The top of the embankment, elevation 175, would be overtopped by about 1 foot. However, failure under this condition would only cause insignificant damage as the downstream flooding would have already occurred. The dam is generally in good condition. However, it is recommended that the owner repair the drawdown outlet, and operate it at least once yearly to insure continued adequacy. After this outlet is repaired, or during a period of low flow, the owner should engage a qualified engineer to inspect the spillway without water flowing over it. Also the erosion of a retaining wall downstream of the spillway on the right abutment side should be repaired.

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.

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.
