Clear Lake is a city in Cerro Gordo County, Iowa, United States. The population was 7,687 at the 2020 census. The city is named for the large lake on which it is located. It is the home of a number of marinas, state parks and tourism-related businesses. Clear Lake is also a major stop on Interstate 35 with many restaurants, hotels and truck stops.
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. By 1853, many more white settlers had also came to settle in the area. By the year 1855, the first Clear Lake school was built as well
