National Program for Inspection of Non-Federal Dams. Risdon Pond Dam (CT 00176), Housatonic River Basin, Waterbury, Connecticut. Phase I Inspection Report
The maximum height of the dam is 27 feet at the left edge of the spillway. The reservoir storage at the top of dam is 11 acre-feet. There are both upstream and downstream spillway training walls composed of mortared and hand placed cobbles respectively. The visual inspection of Risdon Pond Dam indicated that the dam is in fair condition. The inspection revealed that the unprotected upstream face has been slightly eroded by wave action. The downstream face of the dam has a number of blocks which have been displaced, cracked or have unmortared joints, Grass, moss and small trees are growing out of some of the joints. There are several areas of seepage along the downstream wall both sides of the spillway. There is a 3-foot deep depression on the left downstream wall of the dam. Also, there are five large tree stumps along the crest of the dam and a footpath traverses the crest. The spillway will discharge 220 cfs, or 16% of the test flood with the pool level at the top of the dam. The test flood flow of 1420 cfs will overtop the dam by 2.0 feet.
