The largest river by volume flowing into the Great Lakes — the Maumee drains a vast agricultural watershed across northwest Ohio and northeast Indiana before emptying into Lake Erie at Toledo. The river offers big-water flatwater paddling through the Great Black Swamp region. The annual walleye run below the rapids in Maumee and Perrysburg draws anglers from across the Midwest.
