Lake Mendota is a freshwater eutrophic lake that is the northernmost and largest of the four lakes in Madison, Wisconsin. The lake borders Madison on the north, east, and south, Middleton on the west, Shorewood Hills on the southwest, Maple Bluff on the northeast, and Westport on the northwest. Lake Mendota acquired its present name in 1849 following a proposal by a surveyor named Frank Hudson, who claimed to be familiar with local Native American languages; Lyman C. Draper, the first corresponding secretary of the Wisconsin Historical Society, proposed that 'Mendota' could have been a Chippewa word meaning 'large' or 'great.'
