STEP 3: Where is Your School Located on a Watershed?
Find out where your school is located within a watershed.
- Begin by visiting the link: http://www.canadiangeographic.com/watersheds/map/?path=english/watersheds-list Enter your city or town in the search box at the bottom to find your watershed.
- Open Google Maps on a separate tab to locate your school in your city/town.
- Using the Locate My School on a Watershed Handout in the Activity PDF, draw the boundaries of the watershed as found in the tool above. After you have drawn the boundaries of the watershed, locate your school on the map using Google Maps and draw it on the handout. Use proper labels and indicate a distance scale in the bottom right corner.
After you have found your school on the watershed and completed the sketch, discuss the following questions amongst your peers:
- Where does the water from your watershed end up? (a river, a lake, etc.)
- What organizations help manage your watershed? For example, in some areas Conservation Authorities are used. Which level of government is responsible for managing this water system? (is it local or municipal? Is it provincial? Or is it national - federal?
