SOL 6.7: Watersheds 172 The student will investigate and understand the natural processes and human interactions that affect watershed systems. Key concepts include a. the health of ecosystems and the abiotic factors of a
watershed;b. the location and structure of Virginia’s regional
watershed systems;c. divides, tributaries, river systems, and river and
stream processes;d. wetlands;e. estuaries;f. major conservation, health, and safety issues
associated with watersheds; andg. water monitoring and analysis using field equipment
including hand-held technology.

Make your own Watershed
1. Take out a sheet of paper, ball it up and smooth it out 2 times.2. Use blue water based maker to color the tips of the peaks – The Divides3. You are about to make it rain. What do you think will happen?4. Lightly spray the paper5. Where did the water collect, why? This is your lake.6. The path the water took to the lake is a stream.7. Draw a picture of your watershed. Is there more than one on the paper?

Where can airborne
pollutants come from?
Air over our region comes from various areas that change each day.
Most of the air comes from the Midwest and is polluted from power plants and vehicles this doubles the pollution in our area.
Pollutants are washed out of the air by rain and goes into the Chesapeake Bay and its Tributaries.

What is a ecosystem made up of?
An ecosystem is made up of the living community and the non-living factors that affect it. The health of an ecosystem is directly related to water quality.

What abiotic factors affect an ecosystem?
Abiotic factors determine ecosystem type, its distribution of plants and animals as well as the usage of land by people. Abiotic factors include water supply, topography, landforms, geology, soils, sunlight, and air quality/O2 availability.

What human factors can alter the abiotic factors in an ecosystem?
Human activities can alter abiotic components and thus accelerate or decelerate natural processes. For example, people can affect the rate of erosion (a natural process). Plowing cropland can cause erosion, while planting trees can prevent it. Flood protection/wetland loss is another example.

What is water quality monitoring?
Water quality monitoring is the collection of water samples to analyze chemical and/or biological parameters. Simple parameters include pH, temperature, salinity, dissolved oxygen, turbidity, and the presence of macro-invertebrate organisms.

What are found in healthy and unhealthy water systems?
Healthy Systems:1.Clear water2.Algae levels balanced3.Adequate oxygen4.Abundant finfish5.Aquatic plants flourish6.Bottom habitats are healthyUnhealthy Systems:Nutrients feed algae Blooms which decreases oxygen and water clarity. So plants cannot grow, animal life is stressed and Decreased so the food chain is broken and human health concerns begin

How can I help the watersheds?
1. Reduce your daily water usage.2. Never dispose of anything by dumping into a storm drain. Storm drains
lead directly to waterways.3. Use the correct amounts of fertilizer at the correct time for your grass
species.4. Reduce your use of pesticides and fertilizers by re- placing grass with
hardy trees and shrubs.5. Follow label directions carefully on all chemicals and use them only
when necessary.6. Clean up after your pets.7. Maintain home septic systems.8. Create buffers along waterways on your property.9. Know your watershed address.10. Volunteer for clean up, restoration, and conservation programs.11. Promote sustainable land stewardship throughout your community.
