Wallaceburg was once considered to be more vulnerable to floods than any other community in Ontario. It was estimated that over 5000 homes could be affected by a major flood in the Wallaceburg area.

Flooding in Wallaceburg is caused by lake levels, ice jams and runoff. The level of water in the River is usually the same as the level of water in Lake St. Clair. But in Wallaceburg the land around the lake and river is very flat, so when the lake level rises, the extra water ends up flooding into the town. The ice on the top of the water gets jammed up as the river flows to the lake, forming mini-dams. This also forces the water to flow out into the town. "Runoff" is the snow or rain that drains into the river. This happens all the time, but when you combine runoff with ice jams and high lake levels, major floods can result.
