National Program for Inspection of Non-Federal Dams. Hopeville Pond Dam (CT 00438), Thames River Basin, Griswold, Connecticut. Phase I Inspection Program.
Abstract
The dam at Hopeville Pond is approximately 493 feet long (including the overflow spillway) and is an earth embankment structure. The embankment is about 18 feet high with an average crest width of 10 feet. The overflow, concrete-stone masonry vertical fall spillway, is approximately 108 feet in length and located 187 feet from the right abutment. There are two outlet works structures. The dam is judged to be in FAIR condition with several deficiencies that require attention. The deficiencies include: lack of slope protection on the upstream slope, rotting tree stumps on the upstream and downstream slopes, trees growing on the downstream slope, and seepage at the downstream toe and left abutment. The maximum spillway discharge of 3985 CFS represents only 22.9 percent of the routed test flood outflow.
