Book Description
Fitchville Pond Dam is a stone masonry and concrete gravity dam constructed about 1871 and is used solely for recreation. The dam has a height of 27 feet and is approximately 200 feet in length. The spillway is an uncontrolled ogee overflow structure which comprises the right two thirds of the dam. The outlet works for the dam consists of three manually operated sluice gates which discharge flows into a waste way at the left abutment of the dam. Due to its age, Fitchville Pond Dam was neither designed nor constructed by present state-of-the-art procedures. Based upon the visual inspection at the site and the lack of engineering, operational and maintenance data, there are areas of concern which must be corrected to assure the long-term performance of this dam. The dam is considered to be in FAIR condition. The dam is classified as SMALL in size and a SIGNIFICANT hazard structure in accordance with the recommended guidelines established by the Corps of Engineers.

Book Description
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.

Book Description
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.

Book Description
The dam at Hopeville Pond is approximately 493 feet long (including the overflow spillway) and is an earth embankment structure. The embankment is about 18 feet high with an average crest width of 10 feet. The overflow, concrete-stone masonry vertical fall spillway, is approximately 108 feet in length and located 187 feet from the right abutment. There are two outlet works structures. The dam is judged to be in FAIR condition with several deficiencies that require attention. The deficiencies include: lack of slope protection on the upstream slope, rotting tree stumps on the upstream and downstream slopes, trees growing on the downstream slope, and seepage at the downstream toe and left abutment. The maximum spillway discharge of 3985 CFS represents only 22.9 percent of the routed test flood outflow.

Book Description
Pachaug Pond Dam is an earth embankment which has a maximum height of 17.0 ft. and is approximately 770.0 feet long. The dam is considered to be in fair to good condition. A spillway design test flood 24,800 cfs (equal to the PMF) will overtop the dam by approximately 4.0 feet.

Book Description
The Yantic River Dam is an earth embankment with a gravity overflow section. They have a combined length of approximately 323 feet and a maximum height of 18.2 feet. A spillway is located on the northern side of the dam and is approximately 128 feet long. The concrete and masonry spillway is 4 feet lower than the top of the dam. A gate structure and sluiceway near the northern end of the dam supplies water to a downstream factory. There is a 24 inch low-level discharge pipe that passes through the base of the dam at the southern end of the spillway. The pipe is controlled by a gate on the upstream side of the dam and this gate is operable. The drainage area is 39.4 square miles and the reservoir has approximately 77 acre-feet of storage capacity. The assessment of the dam is based on available information, visual inspection and hydraulic/hydrologic computations. The dam is judged to be in FAIR condition with several areas that require attention. These areas include: seepage through the earth embankment and the northern spillway training wall, settlement behind the spillway training wall, cracking and spalling of the sluiceway gate structure and brush and trees on the embankments and along the toe of the dam. The spillway capacity at the top of dam is 2,700 cfs or 44 percent of the test flood outflow. The test flood outflow will overtop the dam by approximately 2 feet.

Book Description
The dam consists of a concrete principal spillway, embankments to the right and left of this spillway and an emergency spillway near the right end of the dam. The principal spillway is a concrete chute with weir-boards at the upstream end and the emergency spillway is an unlined channel cut into the right end of the embankment. A swale, which will overflow to the toe of the dam at approximately the same elevation as the auxiliary spillway, exists at the left end of the dam. There is no low-level outlet at the dam. Based upon the visual inspection at the site and past performance, the dam appears to be in fair condition with items which require repair, maintenance and monitoring. These include spalling of the concrete walls at the principal spillway, seepage through the embankments, trees and brush on the embankments and in the emergency spillway, erosion of the upstream slopes, extending the embankment to fill the swale at left end of the dam, and debris and overhanging brush in the spillway discharge channels. The total spillway capacity at the same pool level is 820 cfs, which is greater than 100% of the routed test flood outflow.

Book Description
The dam, constructed in 1964 and 1965 to replace an earlier dam which failed in 1963 is an earth embankment approximately 435 feet in length with an emergency spillway at its right end. It is approximately 30.5 feet in height and has a maximum design storage of approximately 235 acre-feet. The principal spillway is a drop inlet structure. The dike, built the same time as the dam is approximately 740 feet in length and 18.5 feet in height. The upstream slope is protected by riprap to approximately 3 feet above the normal pool and grassed to the top of the slope. There is a paved roadway along the top of the dike embankment and the downstream slope is grassed and contains a toe drain. Based upon the visual inspection and past performance, the project, is judged to be in good condition. No evidence of instability of either the dam or dike was observed. Peak inflow to the pond at PMF is 780 cubic feet per second (cfs); peak outflow is 490 cfs with the dam and dike maintaining 3.0 feet of freeboard. The combined spillway capacity to the top of the project is 1142 cfs, which is equivalent to 230% of the routed test flood outflow.
