National Program for Inspection of Non-Federal Dams. Curtis Pond Dam (CT 00312), Connecticut Coastal Basin, Newton, Connecticut. Phase I Inspection Report
The entire structure is 235 feet long and consists of a 90-foot-long, 14-foot-high earth embankment extending from the right abutment, a 25-foot-long, 10-foot-high concrete broad-crested spillway weir, and a 120-foot-long 14-foot-high embankment span between the spillway and the left abutment. The top of the embankment is approximately 14 feet wide and is 4 feet above the spillway crest elevation of 327 NGVD. The outlet facilities consist of a 24-inch gated conduit at the base of the concrete spillway and an 18-inch ungated conduit in the left embankment. Visual inspection of the dam indicated that the dam is in poor condition. The inspection revealed considerable spalling and efflorescence of the spillway training walls, an inoperable low-level outlet, heavy vegetation on the dam, and evidence of seepage along the toe of the embankments. The test flood outflow is approximately 1,670 cfs; and the capacity of the spillway, with the water surface at the top of the dam, is 620 cfs or 37 percent of the routed test flood outflow. Therefore, the dam will be overtopped by about 1.2 feet.
