Abstract:

The Wepawaug Reservior Dam is an earth embankment dam with a 90 ft. long concrete ogee spillway. The length of the dam, including the spillway, is approximately 375 feet. The earth embankment has a top width of 15 feet, upstream and downstream slopes of 2 horizontal to 1 vertical, and a maximum height of 16 ft. above stream bed. A concrete core wall with upstream and downstream batters of 1 horizontal to 24 vertical and a top width of 2 ft. extends down to rock. Upstream slope protection consists of riprap placed to within 6 inches of the crest of the dam. Downstream slope protection consists of a heavy growth of grass. The outlets consist of a 30-inch diameter blowoff, and a 4-inch diameter outlet utilized to maintain downstream flow. Both outlets are controlled by manually operated gates located in the gate house at the left end of the spillway. Water is diverted from this reservoir to Maltby No. 3 Reservoir via a diversion tunnel. Flow through the tunnel is regulated by a manually operated gate at the intake structure located at the east side of the reservoir. The general condition of the dam appears to be good.
