Pretend this is all the water in the world.

FRESH WATER. This 2 ½ cups represents all FRESH WATER.

UNFROZEN FRESH WATER. Out of the 2 ½ cups comes ¾ cup representing all UNFROZEN FRESH WATER.

WATER IN LAKES AND RIVERS. This 1 ¼ teaspoons is all the WATER IN LAKES AND RIVERS. ONE-FIFTH OF THIS ( ¼ TSP) IS IN THE GREAT LAKES.

This activity, designed to help students define the boundaries of a watershed, is part of the Watershed Wonderland lesson found at Michigan Geographic Alliance website under Online Resources. How to draw watersheds 9

10 WATERSHED A WATERSHED is the area of land where all of the water that is under it (ground water) or drains off of it (surface water) goes into the same place. drained by a river, river system, or other body of water Watersheds come in all shapes and sizes. A watershed is like a large bathtub. When a drop of water hits anywhere in that bathtub, it eventually finds its way to the drain. The edges of the bathtub define the watershed boundary. They can cross county, state, and national boundaries. Human activity within a watershed in one location can affect all locations separated from other watersheds by higher land (drainage divide)

Watershed Wonderland 11 Find and label the Saginaw Bay and the Saginaw River.

Watershed Wonderland 12 Trace the Saginaw River….

Watershed Wonderland 13 and all its tributaries.

Watershed Wonderland 14 And trace the other rivers flowing into the bay.

Watershed Wonderland 15 Without crossing a river, outline the Saginaw Bay Watershed.

Watershed Wonderland 16 Put a dot on the mouth of the Muskegon River.

Watershed Wonderland 17 Trace the Muskegon River and its tributaries

Watershed Wonderland 18 Without crossing a river, outline the Muskegon River Watershed.

Watershed Wonderland 19 Using 4 different colors, trace the rivers flowing into each of the Great Lakes that surround Michigan.

Watershed Wonderland 20 Drawing boundaries (without crossing a river) shows the watershed boundaries for all the Great Lakes.

Watershed Wonderland 21 These lines represent the higher elevations in Michigan, and are near the sources for all our rivers.

Notice where the rivers of Michigan start! (source) Michigan Elevation Which way do all rivers flow?

The topography of Michigan determines the direction of the rivers in Michigan. Michigan Elevation Explain this sentence:

27 Where does our water come from? Highlands of Michigan

28 Where does our water go? Downhill to Lake Michigan

29 Where does our water go? Can you name the Lakes and Rivers on its journey? Lake Huron Lake Michigan St. Clair River Lake St Clair Detroit River Lake Erie Lake Ontario St. Lawrence River

30 Can you draw the Great Lakes Watershed?

31 Start on the south side of the St. Lawrence River Remember not to cross a river!
