Oneida Lake, located ten miles north of Syracuse in Oneida and Oswego Counties, is the largest lake lying wholly within New York State. Oneida Lake is a relatively shallow natural lake with an average depth of 22 feet. It is named for the Oneida Nation, one of the Haudenosaunee (Iroquois) Nations. The Oneida people call the lake "Tsioqui" or "white water", a reference to the wave action on the lake on windy days.

Aquatic Plant Life:
Since zebra mussels entered the lake in the early 1990's water clarity has improved considerably. This has resulted in increased aquatic vegetation growth. Oneida Lake has very good weed growth, especially along the shoreline and in the larger bays. Vegetation is most abundant in 5 to 15 feet of water; however with the greater water clarity some vegetation may be found as deep as 20 feet.
