Cabot is a six-mile-square New England town located in the northeast corner of Washington County, Vermont, United States. The population was 1,443 at the 2020 census. It contains the unincorporated villages of Cabot Village, Cabot Plain, South Cabot (Hookerville), East Cabot, Lower Cabot, and West Hill. There was also a community known as Petersville until property owners there sold a total of 100 acres to Molly’s Falls Electric Light and Power Company, and in 1925 a large dam was constructed on Molly’s Brook, that completely flooded the area that had been farms and homes to create what is now known as Molly’s Falls Reservoir, or sometimes “Marshfield Dam,” which is located close to the Cabot/Marshfield town line.
