1. Stream Study-Kent Park Group: Blue Abtin Toshtzar, Lindsey Walsh, Ashley Ding, Becky Vandevere, Michael Doyle, Paul Facenda

2. Crum Creek Watershed Picture of the entire Crum Creek Watershed

3. Physical Data • Date: 5/25/2011 • Location: Kent Park • In the Sun air temperature: 27˚C • In the Shade air temperature: 20˚C • No Cloud Cover • Wind: 5mph/ South Wind • No current Rainfall/ No rain in past 24hrs. • Air Temp: 19.9 ˚C • Water Temp: 17.8 ˚C

4. Physical Data… • Average Width: 3.73 m • Average Depth: 0.0925 m • Average Velocity: 0.2244606404 m/sec • Volume of flow: = 0.06195563 m3/sec = 2.23040253 ft3/sec

5. Essential question: 1 • There are various necessities that must be met in order to support a certain organism. Chemically, the dissolved oxygen level, pH level, phosphate level, and nitrate levels must be normal or neutral. Physically, different organisms depend on different temperatures and weather conditions to provide their source of food and to create their habitat.

6. Stream Bottom (Widest)

7. Stream Bottom (Narrowest)

8. SHRUBBERY!! Description of Area • Rocky • Fairly clear waters • Overhanging trees • Grass • Eroded stream bank

9. Widest Point- 4.25m Narrowest Point- 3.25m Mid-Way Point- 3.46m Width of Stream

10. Measurements Widest Point: 9 cm Narrowest Point: 12 cm Midway Point: 11.67 cm

11. Stream Bed Deposits • Composition is sandy with various rocks • Made from large rocks eroded by water over time

12. Stability • Slightly unstable • Due to the constant flow of water the rocks are slightly loose in some places. • Only a few sinking areas

13. Stream Bank Composition • The banks of the stream are made up of hard-packed soil • Supported by the outgrown roots of the trees. • Stream has also been greatly eroded by the gravel and rock particles in the stream bed. • The stream bank shows the previous water levels during heavy rainfall.

14. Stream Bed Shade • More than half; roughly 75% 75%

15. Abiotic/ Biotic factors

16. Velocity of Stream • Widest Point: 39.02 m/sec. • Narrowest Point: 23 m/sec. • Mid-Way Point: 13.86 m/sec.

17. Water Clarity • Water • Translucent • 87 cm in clarity • No odor • Clear and brownish like tea

18. The human impact on this lovely creek is not too bad. There were some water bottles and wrappers, but there was a ton of glass. You should always recycle. Remember kids, THE POWER IS YOURS!

19. Conductivity PIKA-PI! (The stream’s conductivity was 380 µS/cm! That’s normal!)

20. Conclusion • Our site had normal values and concentrations for pH, dissolved oxygen, phosphates, and nitrates. • Therefore, we expected to find a normal or average amount of macro- invertebrates(36) in the stream water.

21. Chemical Data • Day 1 • 16.3°C • Dissolved Oxygen: 9 ppm • Nitrate Concentration: 6 ppm • pH Level: 7 • Phosphate Concentration: 0 ppm • OVERALL: NORMAL

22. Chemical Data Comparison… • Day 2 • 8.2°C • Dissolved Oxygen: 8.6 ppm • Nitrate Concentration: 2 ppm • pH Level: 7 • Phosphate Concentration: 0 ppm • OVERALL: NORMAL

23. ORGANISMS • Day 1 • SOME individual small fish • NO schools of small fish • NO bass • NO trout • NO catfish • NO other • NO dams or waterfalls

24. MORE ORGANISMS! • Day 2 • NO scattered individual small fish • NO scattered schools of small fish • NO bass • NO trout • NO catfish • NO carp • ONE crayfish • NO dams or waterfalls • BUT there were trees/rocks that could hinder movement

25. Algae Observations THERE WAS INDEED BROWN COATED ALGAE, DARK GREEN ALGAE, AND MATTED ONTO THE STREAM BED ALGAE! MWAAHAHAHAH! MY CLOSE COUSINS WILL SOON SUCCEED!!!!

26. Macro Invertebrates! • Day 1 • THREE worms • TWO leeches • ONE scud • TWO netspinners • FIVE most caddisflies • TOTAL= 14

27. Macro Invertebrates….! • Day 2 • TWO worms • THREE leeches • TWO stoneflies • ONE netspinner • TWELVE most caddisflies • SIX midges • TWO most true flies • TOTAL=25

28. Individual Metrics • Mayflies+ stoneflies+ Most caddisflies= 53.8% • Common netspinners= 3.8% • Lunged Snails= 0% • Beetles= 0%

29. % Tolerant • Two worms+ three leeches+ six midges=11 • Value for Metric 5: 11/.42= 42.3%

30. % Non-Insects • Two worms+ three leeches= 5 • Value for Metric 6: 5/.19= 19.2%

31. MMIS • After all calculations, the results are in. • Subtotals • Total number of 2’s: 8 • Total number of 1’s: 1 • Total number of 0’s: 0 • Multimetric Index score is………..NINE! • This is indeed and acceptable ecological condition!

32. Lindsey: I carried the biological test box to and from the stream. I recorded most of the data, preformed the tests that involved going in the stream, and I did some chemical tests.

33. Abtin: I carried the physical box and the kick-net bundle to and from the site. I also had to conduct both the Dissolved Oxygen and the Phosphate test. I helped collect bugs by separating and identifying the bugs with a paint brush. Throughout the whole field trip I wrote down all of the data that we had collected.

34. Ashley: I carried the biology box to and from the creek. I picked up a wrapper, found the water temp. and collected bugs into the ice tray.

35. Michael Doyle: During the trip, I did many things. I helped measure the creek and counted bugs. Also, I filled up the water bottles and counted some insects. Lastly, I carried the chemical box.

36. Paul: I was the fist one in the water. I brought the physical data box, rulers, and the turbidity tube. At the biology station, I held the kick net, corralled the bugs, and identified them. At the physical station, I found the width of the stream for my group. And I found a toad.

37. Becky: (Ad-lib since I lack your info as well. Giggle.) Becky: I carried the chemical box, I put chemicals into the chemical test, I filled water bottles, I dropped the tennis ball in the water.

38. We hope you liked our rockin’ presentation!
