The Unadilla River is a 71-mile-long (114 km)[1] river in the Central New York Region of New York State.[2] The river begins northeast of the hamlet of Millers Mills and flows generally south to the village of Sidney, where it converges with the Susquehanna River, which drains into the Chesapeake Bay,[3] a bay 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.[4]

Branches

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

Tributaries

The Unadilla's tributaries, from north to south, include:
