Lake Eerie is a large lake near Duckburg.
Lake Eerie, a large lake near Duckburg and the primary source of its drinking water, had, by the early 1970's, become damnably polluted, to the point that its waters were corrosive to the touch and became home to a number of mutated lifeforms such as Motor Sludge Catfish and the mysterious Trashivorous Dragon. Some time into 1972, however, heavy rainfall diluted the pollution, killing off part of the Eerie fauna, though reports differ on whether the pollution levels had only decreased a little, or if it had truly become livable for regular people again.
