  1. Cedar River Watershed

  2. 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 using this website: • http://environment.nationalgeographic.com/environment/freshwater/change-the-course/water-footprint-calculator/ • How many gallons of water do you think the average person uses a day in America? (Discuss in small groups)

  3. Daily Water Usages Around the World

  4. Cedar River Watershed • The 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.

  5. Map of the Cedar River Watershed

  6. Wildlife • Home 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!

  7. Cedar River Watershed - Place • Physical 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.

  8. Aquifers • Water seeps into ground and causes water to pool. • Tapped for wells, or water returns to surface as springs.

  9. Invasive Species in the CRW • Invasive 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? http://www.youtube.com/watch?v=1ddKDCwfZTs&noredirect=1

  10. Ecological Preserves • Land 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?

  11. Natural Filtration • The 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?

  12. Normal drinking water filtration systems

  13. Reservoirs • Reservoirs are used to store water, usually drinking water. • Created by dams. • Water routed to cities by pipelines.
