1. The Great Miami River Created By: Vidya Misra, Ke’Avonna Williams, and Kristin Cummings

2. Our Assignment Our assignment was to investigate different methods of water quality on the Great Miami River.

3. Our River Our river is located in southwestern Ohio- near Dayton. It’s 117.0 miles long which makes it a river. The major causes of impairment are flow and habitat alterations, siltation, and nutrient enrichment.

5. Great Miami Land Use Map All the areas that are pink indicate that they are urban areas. The yellow, the major land use, is agriculture areas. Our watershed covers 4,124 square miles of SW Ohio.

6. Definition Page BOD- Biochemical Oxygen Demand QHEI- Qualitative Habitat Evaluation Index ICI- Invertebrate Community Index (macroinvertebrate, or insects) IBI- Index of Biotic Integrity (fish) TSS- Total Suspended Solids

7. Methodology Page Using the internet we found a chart with information about water quality on the Great Miami River. This information was provided by the Ohio EPA. Using this information we created graphs on Microsoft Excel.

8. Hypothesis 1 When the average of total nitrogen increases, the average of BOD increases.

9. Hypothesis 2 As QHEI increases, ICI increases. As QHEI increases, IBI increases also.

10. Hypothesis 3 We think that when there is a low level of TSS, there are high levels of IBI and ICI.

16. Conclusion In conclusion to our project, we found out that the Great Miami is a healthy river. It has good levels of nitrogen, BOD, IBI, ICI, and TSS.

17. Acknowledgements We would like to thank Sue Brown, Steve Gordon, and Virginie Bouchard for making this program possible for us. Also, a special thanks to Nikki Husat- our group leader who has helped us with this project a lot.
