National Program for Inspection of Non-Federal Dams. Morris Reservoir Dam (CT 00473), Naugatuck River Basin, Morris & Litchfield, Connecticut. Phase I Inspection Report.
Abstract
Morris Reservoir Dam is an 800 foot long earth embankment dam and has a maximum height of 110 feet. Top width of the dam is 20 feet and appurtenant structures include a concrete spillway, spillway channel and outlet works. The spillway is on the right (west) side of the dam. The visual inspection of Morris Reservoir Dam indicated that the dam is in good condition and is well maintained. The inspection revealed that a surficial erosion channel up to 8 inches in depth is located on the downstream slope approximately 150 feet east of the spillway starting at the third berm down from the crest and extending to the toe. Occasional animal burrows were found on the downstream face of the dam. Loose rock and trees were observed overhanging the west side of the downstream channel. Slight erosion adjacent to the east side of the gate structure was observed. Occasional water observed on the berms is believed to be melt water. The spillway will pass the test flood outflow of 15,575 cfs with a pool elevation of 659.6 feet MSL which is 1 foot below top of dam.
