Mapping the river watershed area
- Have a discussion about all possible surface waters in your neighborhood:
- Do you know from where streams, rivers, lakes, ponds, lagoon in your town get their water?
- How large is the watershed of your river?
- Making the map of watershed:
- Take a map of the province. Cover the map with translucent tracing paper.
- Choose a stream, river, or lake in your vicinity, and trace it down on translucent paper.
- Try to define the borders of the watershed by defining the high ridgeline. Draw the borders of the watershed on translucent paper.
- Are there any dams or reservoirs? If yes, draw them on the paper.
- Are there any wetlands? If yes, draw them on the paper.
- Have a discussion and attempt to describe how the water system functions in a chosen watershed.
- From where does the river, stream, or lake receive its water?
- Does the river run through a canal or is it natural? How does this affect the flow of the river or stream?
- Is there a large flood plain along the river or stream that is flooded every year? What can happen if we build a new town on the floodplain?
- Take a pencil and drop it on the map. The end-point of the pencil shows the location of water contamination with poison that was accidentally spilled because of a car accident.
- Which streams and rivers in the river watershed will be contaminated?
