Cedar River Watershed
How much water do you use a day?Quickly answer the handout that you have
received with your best guesses. We will make a class water usage footprint by

How many gallons of water do you think the average person uses a day in America? (Discuss in small groups)
Daily Water Usages Around the World
Cedar River WatershedThe Cedar River Watershed is the land area where rainwater drains into the Lake Washington and eventually meets the sound by passing through the Ballard locks.
Map of the Cedar River Watershed
WildlifeHome to 88 species of fish and wildlife
14 species are close to being endangered.Sockeye salmon and Chinook salmon.
Some of the best salmon habitat in Washington!
Cedar River Watershed - PlacePhysical characteristics:
Starts in Cascade Mountain Range
Flows into Lake Washington
A large amount of water seeps into the ground making an aquifer.
Human Characteristic:Provides water to 22% of Washington’s
population.
AquifersWater seeps
into ground and causeswater to pool.
Tapped for wells, or water returns to surfaceas springs.
Invasive Species in the CRWInvasive species are plants and animals that
are non-native to the area. http://www.youtube.com/watch?v=-OyGHH_LG2A&noredirect=1
Talk in your table groups, what does non-native mean?
How might non-native species affect an environment?

Ecological PreservesLand protected and managed in order
to preserve a particular type of habitat and its flora and fauna, which are often rare or endangered.
Talk in table groups,Have you ever been to an ecological preserve? Where?
Why are ecological preserves important?
Natural FiltrationThe CRW is one of the largest watersheds in the
country that naturally filters its water.
A lot of watersheds that are used as drinking water sources need specially fabricated filtration systems.With chemicals at filtration plants.
Talk in table groups,What’s raw water?
Normal drinking water filtration systems
ReservoirsReservoirs are used
to store water, usually drinking water.
Created by dams.
Water routed to cities by pipelines.
