  1. *Stillwater watershed project* • By: Group 2 • Meah Kee • Tiffany Yang • Lesley Preece • Teacher: Melanie

  2. *Definitions* • Watershed- drainage basin for a stream • IBI- the number of fish species in the watershed. • ICI- the number of macro- invertebrates in the watershed • QHEI- index used to determine habitat quality

  3. Methods • To find out how many species of fish are in a watershed (IBI), we use electrofishing. ( Shocking the fish to make them swim to our nets.) • To find out how many macroinvertebrates are in a watershed we drop nets and disturb the substrate.

  4. Background of Stillwater • Location: Located in Eastern Ohio, bordering Indiana. Montgomery, Darke, and Miami counties contain the watershed • Land: 80% of the land is cropland. Some hay and lots of row crops. Some small cities and towns

  5. Background of Stillwater Cont. • Large number of live- stock and poultry operations in the upper part of the watershed resulted in high bacteria and high levels of nutrients.

  6. Stillwater • Stillwater is on the priority list for impaired waters in Ohio. • EPA has projects going on to improve it. • It contains some macro- invertebrates and 59 fish species and has birds such as wood duck and the great blue heron

  7. Hypothesis # 1 • As maximum total nitrates increases IBI (fish) decreases.

  8. Analysis • Nitrates in the water are there because of run off from farmers’ fields. • Nitrates are harmful to fish and humans. • They are found in fertilizers. • The Stillwater watershed is 80% cropland.

  9. Conclusion to hypothesis # 1 • From looking at the graph we came to the conclusion that our hypothesis is supported. • It is because the places that have more nitrates also have less fish.

  10. Hypothesis # 2 • As the QHEI ( habitat quality) increases the ICI (macro- invertebrates) increases

  11. As you can see here there is one place that is the exception to our hypothesis. We know there is a discrepancy because there is one place where the QHEI decreases and the ICI increases. We researched this area and could not figure out why this occurred. Analysis

  12. Conclusion of hypothesis # 2 • This information supported our hypothesis • As the QHEI increased the ICI increased

  13. Hypothesis #3 Our hypothesis was: As the percent of deciduous forests increases, the ICI increases.

  14. Analysis • We graphed the information • Percent of deciduous forests increased, ICI increased • Exception of location seven • Our research could not find conclusion to discrepancy

  15. Conclusion to hypothesis #3 • Our conclusion supported hypothesis • Where there was a high percentage of deciduous forests, the ICI was high also.

  16. Improvements • EPA sponsoring improvement projects • Reduce oil erosion • Encourage manure management • Restore wetlands • Reduce septic loading • Restore riparian zones • Stillwater: greatly improved in past seven years

  17. Thank you YWSI, OSC, and especially Melanie. *The End*
