Flowing from the mouth of Lake Huron into Lake Erie, the Huron-Erie Corridor (HEC) consists of the St. Clair River, Lake St. Clair, and the Detroit River. The southwestern Ontario and southeastern Michigan watersheds are also a part of the corridor, as they drain into the three water features. The HEC is an international route, which makes it one of the busiest navigation centers in the United States. It is also a fish migration corridor, containing important spawning and nursery grounds.
