Overview of Project
• Conducted in Eau Claire County, Fall Creek Wisconsin
• From October 2000 to May 2001.
• Worked with Paul Tweed, biology teacher of Augusta and Scott Thiel, science teacher at Altoona and Beaver Creek Reserve and staff.

Why we chose the stream?
• We can’t see inside the stream, like we can on the ground.
• Find what is in our water.
• See how pollution affects our water and the living organisms that live in the water as well.

Hypothesis
•Beaver Creek Watershed has a good water quality rating.
![Page 5: Stream Pollution Assessment of Beaver Creek](https://reader036.vdocuments.us/reader036/viewer/2022070413/56814ce2550346895db9e52b/html5/thumbnails/5.jpg)
What is our project?
• Insects
• Fish
• Chemicals
• Temperatures
![Page 6: Stream Pollution Assessment of Beaver Creek](https://reader036.vdocuments.us/reader036/viewer/2022070413/56814ce2550346895db9e52b/html5/thumbnails/6.jpg)
Insect collections
• Disrupt stream bottom into D-framed net
• Empty all of contents into collection pan
• Remove 100 insects randomly (to avoid a bias collection)
![Page 7: Stream Pollution Assessment of Beaver Creek](https://reader036.vdocuments.us/reader036/viewer/2022070413/56814ce2550346895db9e52b/html5/thumbnails/7.jpg)
Use a D-framed net

Identify the Family of Each Insect
• Some determinates of insect families include: body shape, gill structure, wings, mandible, and abdomen.
• Use FBI key by looking at these features

Temperature
• Change in stream temperature between the hobos.
• Temperature recorded by hobos, small devices that records temperature every 4 hours.
• Placed 2 hobos in the stream one mile apart
• Placed 1 above the stream
![Page 11: Stream Pollution Assessment of Beaver Creek](https://reader036.vdocuments.us/reader036/viewer/2022070413/56814ce2550346895db9e52b/html5/thumbnails/11.jpg)
Why Collect Temperature Data
• Correlation between fish and temperature
• Correlation between dissolved oxygen and temperature
• Change is temperature between two hobos in stream
![Page 12: Stream Pollution Assessment of Beaver Creek](https://reader036.vdocuments.us/reader036/viewer/2022070413/56814ce2550346895db9e52b/html5/thumbnails/12.jpg)
Chemical Tests
• Collect Water Samples from 2 sites
• Analyze in Lab for concentrations
• Decipher change
![Page 13: Stream Pollution Assessment of Beaver Creek](https://reader036.vdocuments.us/reader036/viewer/2022070413/56814ce2550346895db9e52b/html5/thumbnails/13.jpg)
Nitrate Information
• NO3
• Found in farm fertilizers
• Promotes plant growth
• Too much pollution causes a decrease in oxygen
• U.S. Public Health Service only allows 10 mg/L. in public drinking water

Phosphate Information
• PO4
• Found in fertilizers and pesticides
• Stimulates plant growth
• .1 mg/L. is recommended maximum for rivers and streams

Turbidity
• Measure of sediment in water
• Enables us to determine whether erosion or excessive growth is taking place

Dissolved Oxygen Information
• O2 dissolved in water
• Diffusion from surrounding air
• Photosynthesis
• Reduced by decomposition of excessive plant growth

Fish Collections• Placed 2 minnow traps one mile apart
at Field Station• Collected every 4-7
days• Measured and
identified each minnow

Summary
• From chemical tests we found stream has high phosphate levels but all other tests indicated good quality
• Insect tests indicated overall good quality with minimal change
• Temperature data fluctuated normally
• Minnows found were typical of habitat
![Page 26: Stream Pollution Assessment of Beaver Creek](https://reader036.vdocuments.us/reader036/viewer/2022070413/56814ce2550346895db9e52b/html5/thumbnails/26.jpg)
Concerns
• Tests valid
• Phosphate levels
• Future interests in the Beaver Creek Watershed
![Page 27: Stream Pollution Assessment of Beaver Creek](https://reader036.vdocuments.us/reader036/viewer/2022070413/56814ce2550346895db9e52b/html5/thumbnails/27.jpg)
Closing Comments
• More work than we had anticipated.
• Great class, but students must be committed because this individual work.
• Only factor that would make this class even better is more time.
