Before European settlement, numerous Winnebago Indian villages and camps could be found on Lake Mendota's shores. About 350 effigy mounds built by the Winnebago have been identified around Lake Mendota and over 1,000 in the four lakes area. A bird effigy on the Mendota hospital grounds is one of the finest and has a wing spread of 624 ft.
The Winnebago called the Four Lakes Region Tay-cho-pe-ra. They called Lake Mendota Wonk-shek-ho-mik-la. In 1849 a Madison surveyor, Frank Hudson, named the lake “Mendota” after the Sioux term meaning "mouth of the river."
More information can be found on a historical marker at the park.
