Oneida Lake is the largest lake entirely within New York (79.8 square miles). The lake is located northeast of Syracuse and near the Great Lakes. It serves as one of the links in the Erie Canal. It empties into the Oneida River which flows into the Oswego River which in turn flows into Lake Ontario. It is named for the Oneida tribe of the Iroquois who live in the area. While not included as one of the Finger Lakes, it is sometimes referred to as their "thumb".
