Downsville is a hamlet and former village within the town of Colchester in Delaware County, New York.
It is the site of the Downsville Bridge, a covered bridge and the historic Union Free School.
Downsville is named for Abel Downs, who had a tannery there.
Downsville is located on the East Branch of the Delaware River. A dam on this portion of the river, at Downsville, was completed by locals paid for by New York City in 1954, creating the Pepacton Reservoir, which is part of the New York City water supply system.
Downsville Central School, located on Maple Avenue, serves families from the surrounding areas, including municipalities as far away as East Branch. Downsville Central School's colors are purple and white and their mascot is the Eagle.
