National Program for Inspection of Non-Federal Dams. Winnipauk Dam (A/K/A Flock Process Dam) (CT 00531), Norwalk River Basin, Norwalk, Connecticut. Phase I Inspection Report.
Abstract
The Winnipauk Dam is a run-of-the-river dam consisting of a stone masonry wall with a concrete cap and an upstream earth embankment. The dam has an overflow crest length of 75 feet, a maximum height of 22 feet and outlet works at the left abutment. There was 0.3 feet of water going over the spillway at the time of inspection, so the condition of the stone masonry wall could not be observed. The concrete weir appeared to be in fair condition. The weir had what looked to be wood planking on both the upstream and downstream edges. The outlet works at the left abutment consist of a stone masonry and concrete structure with a 5-1/2-ft. by 5-1/2-ft. sluice gate on the upstream side which discharges through a partially collapsed 6 foot wide by 4 foot high stone archway at the toe of the left abutment. The sluice gate is obstructed with leaves, sticks and debris and appears to be inoperable. The concrete top of the outlet structure is partially collapsed and the chamber is filled with debris. The dam has a watershed of 33 square miles and a water surface area of less than two acres. The pond is completely silted in. The maximum height of 22 feet and the storage capacity of 40 Acre-Feet are both below the requirements for a Small dam. The dam, therefore, does not qualify for inclusion in the Corps of Engineers' Inspection Program.
