Dam No.2 along Spaulding Pond Brook is an earth embankment structure. It is 12 feet wide at the creat, 200 feet long and 16 feet high. Both the upstream and downstream slopes are about 3H1V. There is partial riprap protection on the upstream slope. The principal spillway consists of a reinforced concrete drop inlet structure with trash racks and a 30 inch diameter reinforced concrete pipe. There is a grassed emergency spillway 100 feet wide in the left abutment. A dike approximately 900 feet long surrounds the reservoir on the easterly side. The maximum height of this earth embankment dike is 15 feet. The dam is located downstream from Spaulding Pond Dam No. 1 on the Spaulding Pond Brook. The maximum storage capacity of this facility is 63 acre feet at the level of the top of the dam, and its drainage area is approximately 0.45 square miles. The dam is a single purpose flood prevention dam which is intermittently used in the winter months for ice skating. It was constructed in 1968 by the City of Norwich with the assistance of the Soil Conservation Service. As a result of the visual inspection, hydrologic and hydraulic computations and the review of the design plans and specifications, the dam is considered to be in GOOD condition. To assure the long term performance of this structure a few items of concern require attention. Most of these are maintenance items and include the restoration of the surface along the crest of the dam, removing brush and debris from the culvert under the road and from the outlet channel, and cleaning debris from a drain outlet at the base of the dike.
