National Program for Inspection of Non-Federal Dams, Fairview Reservoir Dam (CT 00205), Thames River Basin, Norwich, Connecticut. Phase I Inspection Report
Fairview Reservoir Dam is an earth dam with a masonry core wall constructed around 1868 and is used today as a standby water supply for the city of Norwich. The dam has a maximum height of 28.0 feet and is approximately 520.0 feet long, with a top width of 27.0 feet. There are four auxiliary dikes at the north end of the reservoir; all four dikes are earth embankments of the same construction and similar to the main dam. The outlet spillway is located in the Northwest Dike and is 27.0 feet long. The dam is considered to be in FAIR condition. Several visible signs of distress which indicate potential hazards are: seepage at two spots at the downstream toe of the dam, seepage through the roof of the valve chamber, rotting stumps on the main embankment, trees and shrubs on the downstream face of the main dam and both faces of all the dikes, structural deterioration of and seepage from under the spillway, rusted outlet conduits at the valve chamber with valves frozen in the open position allowing constant pressurized outlet pipes to pass through the embankment, and a general lack of regular maintenance. The maximum spillway discharge is 648 cfs, or abut 48 percent of the test flood outflow.
