The Mohawk River is a 149-mile-long (240 km) river in the U.S. state of New York. It is the largest tributary of the Hudson River. The Mohawk flows into the Hudson in Cohoes, New York, a few miles north of the city of Albany. The river is named for the Mohawk Nation of the Iroquois Confederacy. It is a major waterway in north-central New York. The largest tributary, the Schoharie Creek, accounts for over one quarter (26.83%) of the Mohawk River's watershed. Another main tributary is the West Canada Creek which makes up for 16.33% of the Mohawks watershed. Source: Wikipedia
