Lake Manitou is a man-made lake in Rochester, Indiana, created in 1827 by the federal government of the United States for the Potowatomi Native American tribe.

The lake was created as a part of the treaty with the Potowatomi that required the U.S. government to create a mill for Potowatomi use.

[1] The Potowatomi originally called the lake Man-I-Toe which translated to the Devil's Lake due to the belief that a monster lived in the lake.

[2] The lake contains about 775 acres (3.14 km2) of open water,[3] with a maximum depth of 65 feet (20 m).
