 The region around the lake that would later be called Clear Lake was a summer home to the Dakota and Winnebago American Indians.During a land survey of northern Iowa done in 1832 by Nathan Boone, the son of the famous explorer, Daniel Boone, a map was made showing the lake and other bodies of water in the area.In 1851, Joseph Hewitt and James Dickirson brought their families to camp on the east side of Clear Lake, soon building a cabin, and began a friendship with the Winnebago natives.
