Unadilla River

The Unadilla River in New York State flows 71 miles (114 km)^[1] from south of Utica to the village of Sidney, where it flows into the Susquehanna River, which eventually empties into the Chesapeake Bay, an arm of the Atlantic Ocean.

Most of the length of the Unadilla forms the western border of Otsego County and the eastern borders of Chenango and Madison counties, all in New York. This border made up a significant portion of the Fort Stanwix Treaty Line of 1768. It was meant to establish the border for an Indian reserve, beyond which European-American settlers were not supposed to go. Settlers resented British efforts to control their movements, and continued to encroach on Native American territories.

Branches

The Unadilla has two branches which join at Unadilla Forks on the Otsego-Madison County border.

• The main branch of the Unadilla starts at Unadilla Lake, at Miller's Mills in southwestern Herkimer County.
• The West Branch of the Unadilla starts a few miles north of Bridgewater in southeast Oneida County. This branch was known as Eghwagy Creek during the early 18th century.
