The Watershed Concept


Michigan Environmental Education Curriculum

Alt | Win

Water reaches the earth’s surface as rain and snow. A portion of the water falling on land seeps into the soil or flows over the surface before entering streams and lakes. The land area that supplies water to a particular river or lake is called a watershed. We manage watersheds and the water they produce to provide for agriculture, human consumption, industry, flood control and recreation. In this exercise, you will learn more about what makes up a watershed, track the movement of water through the hydrologic cycle and explore ways in which scientists and engineers work to manage water resources.
