National Program for Inspection of Non-Federal Dams. Dobsonville Dam (CT 00210), Connecticut River Basin, Vernon, Connecticut. Phase I Inspection Report
Dobsonville Dam is a run of the river stone masonry gravity dam. The total length of the dam is 84 feet with a maximum height of 26 feet. The crest width of the dam is approximately 10 feet. The centrally located spillway is 62 feet in length. The stones forming the crest of the spillway are connected with metal rods. The dam was originally constructed to provide water power for a mill, however the ponds is now used for passive recreation only. Dobsonville Dam has a storage volume of 125 acre-feet and a maximum dam height of 26 feet. Based on the visual inspection, the Dobsonville Dam and its appurtenances are judge to be in fair condition. The vertical and horizontal alignment was good. Trees are located at the abutments with roots growing into the stone masonry face. Seepage was observed eminating through the downstream face. Water was overflowing the spillway at the time of inspection. The maximum spillway capacity without overtopping the dam is 342 CFS. The capacity of the spillway is inadequate to pass the 100 year test flood outflow fo 4290 CFS and would overtop the dam by 5.7 feet. The spillway is adequate to pass only 8 percent of the spillway test flood outlfow without overtopping the dam.
