Although there are no natural lakes of significant size in Wolcott, several man-made reservoirs have been created from the damming of small rivers and brooks. Scovill Reservoir, also known as Woodtick Reservoir, covers and was built by damming the Mad River in central Wolcott. Originally constructed in 1917 to supply water for the Scovill Manufacturing Company, a brass manufacturing mill, it is now a town-owned recreational lake. Other reservoirs that are at least partially contained within Wolcott include Chestnut Hill Reservoir, Hitchcock Lake, Southington Reservoir #2, New Britain Reservoir (which extends east into neighboring Southington, Connecticut) and Cedar Lake and Dunham Mill Pond (both of which extend north into neighboring Bristol, Connecticut).
