The next time it rains, watch the water run off your roof, your driveway, down the street. Everywhere you go, water is on its way to the nearest stream, lake, or wetland. Some of it soaks into the soil to become groundwater and slowly replenish streams and lakes.
Some runs overland.
When you add up all the land that catches water and drains it to the same waterway, you have a watershed. Parts of seven counties in southeast Michigan drain to the Huron River and make up its watershed. The Huron, in turn, drains into Lake Erie and is part of the Great Lakes Watershed. View a map of the Huron River watershed , or a map of Michigan watersheds that shows how the Huron River Watershed fits into the larger system. Picture yourself canoeing on the Huron River.
