The Mohawk River is a 149-mile-long (240 km)[5]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 state capital of Albany.[10] The river is named for the Mohawk Nation of the Iroquois Confederacy. A major waterway, in the early 19th century, the river's east-west valley provided the setting and water for development of the Erie Canal, as a key to developing 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 Mohawk's watershed.
