According to local legend, Wauconda was named after an indigenous chief whose name translated as “spirit water”.

“Waconda,” it says in the Otoe language, Great Mystery, meaning that vital thing or phenomenon in life that cannot ever be entirely comprehensible to us. What is understood though, through the spoken word, is that silence is also Waconda, as is the universe and everything that exists, tangible and intangible, because none of these things are separate from that life force. It is all Waconda. . . .” [Anna Lee Walters, Talking Indian: Reflections on Survival and Writing (Ithaca, N.Y.: Firebrand Books, 1992), 19–20.]

Many early settlers of Wauconda came from New England and New York by covered wagon or through the Erie Canal and the Great Lakes.

Elihu Hubbard built the first log cabin on the bank of Bangs Lake in 1836. Justus Bangs, the first settler in Wauconda, built a house next to the lake in 1848 and the lake was later named after him. In 1840, members of the Winnebago tribe who did not leave the shores of the Fox River often went to the area to trade.
