National Program for Inspection of Non-Federal Dams. Miller Pond Dam (CT 00154), Thames River Basin, Waterford, Connecticut. Phase I Inspection Report
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.
