National Program for Inspection of Non-Federal Dams. Menuckatuck Reservoir Dam (CT 00408), Connecticut Central Coastal Area, Guilford, Connecticut. Phase I Inspection Report
Menuckatuck Reservoir Dam is a concrete gravity structure with a downstream earth embankment. The total length of the dam is 248 feet with a maximum height of 58 feet. A 42 foot wide concrete gravity spillway section is located at the right side of the dam. Concrete steps on the downstream face transmit flow to a concrete spillway raceway 300 feet long that discharges to a bedrock channel. The outlet works consist of an intake gatehouse for drawing off water to the supply system and a 36 inch diameter cast iron pipe that serves as the low level outlet. The dam is judged to be in generally good condition. The concrete surfaces were recently gunited and are in good condition. The horizontal and vertical alignment is good. The downstream earth embankment is well-maintained and did not show any evidence of sloughing or seepage. Slight erosion of the embankment was trees have been planted along the crest of the downstream embankment. The concrete spillway weir and spillway raceway are in good condition with minor seepage at construction joints on the floor of the spillway raceway. The capacity of the spillway is inadequate to pass the full PMF test flood outflow (7030 CFS) without overtopping the dam.
