The purpose of this activity is to make a model that shows how rivers and lakes are connected in a watershed.
Make it happen
The way water moves through rivers and lakes depends on the shape of the land! A watershed is the area where rivers and lakes are connected. In a watershed, all streams and rivers come together into one body of water like a larger river, lake, or reservoir. Mountains or other high ridges may separate some rivers in your map. These rivers are in different watersheds. If all the rivers come together in your map you’ll have one watershed.
