The dam, built in the 1870's, has a total length of approximately 425 feet and consists of an embankment section with upstream and downstream masonry faces and a masonry spillway section. The dam is 19.5 feet in height above the old streambed of Hunts Brook and, with the pond level to the top of the dam, impounds approximately 700 acre-feet of water. The spillway is an 87.8 foot long broad-crested weir located at the right end of the dam and is founded on bedrock. Based upon the visual inspection at the site and past performance, the project is judged to be in poor condition. There are areas which require monitoring and/or maintenance such as: seepage at several locations on the downstream face and toe of the dam, seepage of the low-level outlet culvert, the inoperable low-level outlet gate, eroded areas on the top of the dam, deteriorated masonry at several locations on the dam, and possible erosion or undermining due to high velocity flows along the downstream toe of the spillway and dam. Peak inflow to the reservoir at the 1/2 PMF is 8,610 cubic feet per second; peak outflow is 7,730 cfe with the dam overtopped by 2.7 feet. The spillway capacity with the reservoir level to the top of the dam is 1,610 cfs, which is equivalent to 21% of the routed test flood outflow.

The Packers Pond Dam, built about 1880 to provide water for industrial use, is an earth embankment impounding 450 acre-feet of water on Mill Brook. The length of the dam, including the spillway, is 325 feet. The top of the dam averages between 12-15 feet in width and is approximately 18 feet above the old streambed at the spillway discharge channel. The spillway, located at the right end of the dam, is a 64 foot long, broad-crested, stone masonry structure which provides 4.4 feet of freeboard from the crest to the top of the dam. The outlet is a concrete intake and gate structure located on the upstream slope at the left end of the dam. The gate is not functional and the size of the outlet could not be exactly determined. However, the outlet is assumed to be approximately 3 feet wide by 2.5 high. A railroad embankment runs along the downstream toe of the dam. This embankment is about 24 feet in height, with the top of the embankment approximately 12 feet higher than the top of the dam. The spillway capacity with the pond level at the top of the dam is 1700 cfs, which is 28% of the routed test flood outflow.

The dam, built around 1920, has a total length of approximately 400 feet, consisting of a 184 foot long board-crested masonry spillway, a 190 foot long earth embankment, and a 27 foot long sluiceway. The top of the embankment, at elevation 88.7, is approximately 20 feet wide, 8.7 feet above the spillway crest, and 23 feet above the streambed of the Little River. With the pond level to the top of the dam, the pond impounds approximately 1000 acre-feet of water. The sluiceway at the left end of the dam leads to abandoned factory buildings about 400 feet from the dam. The intake to the sluiceway is a wood bulkhead, which contains 5 gates. Based upon the visual inspection at the site and past performance, the project is judged to be in poor condition. No evidence of instability of the project was observed. However, there are items which require maintenance, such as the dense vegetation on the embankment and the inoperable sluice gates. The spillway capacity with the pond level to the top of the dam is 13,000 cfs, which is equivalent to 108% of the routed test flood outflow.

Papermill Pond Dam is a 573 ft. long composite rubble masonry, concrete, and earth embankment dam consisting of a 124.5 ft. long gravity masonry overflow section, and 84 ft. long earth embankment to the right of the overflow section and a 365 ft. long earth embankment to the left of the overflow section. About 160 ft. of the upstream face of the left embankment is paved with concrete. It is a run-of-the-river dam which is used for storing process water for a paper mill located upstream on the left bank of the river. In the left embankment there is an intake which controlled flows through a conduit to a turbine facility in a mill building located immediately downstream of the dam. The turbine has been abandoned and the mill building is in the process of being razed. The spillway for the dam is equipped with 2.3 ft. high permanent wooden flashboards. The dam is judged to be in generally good condition, but is rated as in fair condition owing to the absence of a dewatering facility. There is brush growth on both embankments. Mortar is missing from the joints of the rubble masonry section of the spillway. There is a crack in the concrete apron on the left embankment and the construction joints of the apron have opened up. Minor erosion has taken place on the downstream slope of the left embankment. The spillway can pass 7,750 cfs or about 72 percent of the routed test flood outflow without overtopping the right embankment.

Mill Pond Dam is an earth-covered, irregular natural rock formation 600 ft. long, with a top width varying from 10 to 20 ft. and a maximum height of 19 ft. The outlet for the dam is a natural rock weir spillway approximately 35 ft. wide, which is overpassed by a footbridge. The crest of the spillway is about 3 ft. below the lowest point on the dam crest. Based on visual inspection, the Mill Pond Dam is judged to be in good condition; however, during the inspection, there was a light snow cover of approximately 2 inches which may have obscured problems, such as erosion or seepage. A test flood of a 100 year frequency was selected in accordance with the Corps of Engineers' Guidelines. The calculated test flood inflow of 1,000 cfs results in a routed outflow of 990 cfs. With the water level at the top of the dam the spillway capacity is 575 cfs which is 58% of the outflow flood. The storage capacity of the Mill Pond is 52 ac.-ft. at the top of the dam.
