Book Description
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.

Book Description
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.

Book Description
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).

Book Description
The dam is about 48 ft. long and 13 ft. high. It is constructed of cut stone masonry. The dam is generally in poor condition. The right end of the dam has had a partial failure at the crest. The dam is classified as small in size with a hazard potential of low. Recommendations for remedial work include repair of the failed area at the right end of the crest of the dam, the plugging of pressure leaks in the dam and mortaring of open joints, and the repair of erosion damage at the right abutment.

Book Description
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.

Book Description
The impoundment structures on Barre Reservoir consist of a 225-foot long earthfill dam and a 410-foot long earthfill dike. The spillway consists of a flat-crested, concrete weir 68.3 feet long and the low-level outlet is a 12-inch diameter iron pipe located at the dike, approximately 70 feet to the right of the left abutment. Generally, the dam and dike are in poor condition. The following deficiencies were observed at the site: severe seepage from the downstream toe of the dike at the left abutment; seepage along almost the entire length of both the dam and dike, at the downstream toe; heavy growth of vegetation on the crest and slopes of both the dam and dike; seepage through the vertical downstream stone spillway wall and beneath both left and right sidewalls of the spillway channel; minor bulging of the vertical stone spillway wall; spalling of the concrete approach apron, spillway crest, and splash apron, slight to heavy spalling of concrete along the upstream face of the spillway sidewalls; and an accumulation of debris in the spillway discharge channel. The test flood would overtop the dam by 0.1 feet but would not overtop the dike. Hydraulic analyses indicate that the spillway can discharge 1,370 cfs, or 93 percent of the test flood outflow before the dam is overtopped.

Book Description
Mill Pond Dam is an earth embankment dam believed to have been constructed around 1900. The facility is used as a bridge across the Agawam River and to impound water for recreational purposes. The dam is about 285 ft. long and 16.5 ft. high. The dam has two spillways. The primary spillway is a concrete sluiceway located near the left abutment. A two bay stoplog structure located at the downstream end of the sluiceway controls flows through the facility. The secondary spillway is a 5 ft. dia. metal pipe culvert located on the right side of the dam. A stoplog structure having a weir length of 5.4 ft. is located on the upstream end of this spillway. An 18 in. dia. outlet passes through the dam near mid-point. Outflow is controlled at a 6 ft. by 8 ft. by 6 ft. upstream concrete intake structure. The dam and appurtenant works are judged to be in fair condition. There is no low level outlet for draining the pond. Seepage was noted at four locations. There was erosion of both the upstream and downstream embankments in the vicinity of the 18 in. dia. outlet pipe. Tree and brush growth is abundant. The test flood inflow is 3,420 cfs; the routed test flood outflow of 3,150 cfs would overtop the low point in the left abutment by about 2.0 ft. The spillways can pass about 7 percent of the routed test flood outflow without overtopping the low point in the left abutment.

Book Description
Paper Mill Pond consists of a 17 foot long concrete spillway and a 15 foot long concrete dam, all completely surrounded by buildings of Amerbelle Corporation. At top of a dam elevation, the dam impounds 90 acre-feet. Outlet works consist of a drawdown conduit of unknown size and twin 8-inch line for process water. Under normal conditions, the entire flow of the Hockanum River discharges over the spillway. This dam has a maximum height of 16.7 feet with the top of dam 5.5 feet above the spillway crest. The dam is in fair condition with some seepage from the face of dam and some deteriorated concrete. In addition to the operable outlet works, there is the 48-inch metal penstock that was originally used to supply water to the generator turbine. This outlet is plugged and the pipe partially filled and collapsed.

Book Description
Shaker Mill Pond Dam consists of a gunite covered concrete and masonry spillway structure between approach channel walls and abutting earth roadway embankments. The overall length of the dam is about 50 ft. and its maximum height is 20.4 ft. There are two regulating outlets at the dam site. The dam is in fair condition, based on a visual examination of the structure. Several deficiencies, mainly due to deterioration, were noted. However, there was no evidence of settlement, lateral movement or other signs of structural failure of the dam, or other conditions which would warrant urgent remedial action. With the water level at the top of dam (level of Route 102 bridge deck), the ungated spillway capacity is approximately 1,600 cfs which is 6 percent of the test flood outflow.
