It is part of the Fox–Wisconsin Waterway and receives its inflow from a short segment of the Fox River which drains from the north end of Lake Winnebago around Doty Island.

The north end of Little Lake Butte des Morts becomes the section of the Fox River running to Green Bay.

The lake is part of the Butte des Morts region in Winnebago County, Wisconsin.

French archives state that in 1716, over 8000 civilians and over 500 soldiers lived within the fortified walls of Little Lake Butte des Morts.

[1] The Roland Kampo Memorial Bridge which carries the Tri-County Expressway (WIS 441/US 10) crosses the lake.
