Description
Oneida Lake is the largest lake entirely within New York state, with a surface area of 79.8 square miles (207 km2). The lake is located northeast of Syracuse and near the Great Lakes. It feeds the Oneida River, a tributary of the Oswego River, which flows into Lake Ontario. From the earliest times until the opening of the Erie Canal in 1825, the lake was part of an important waterway connecting the Atlantic seaboard of North America to the continental interior.
