Our Assignment

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

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.

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.

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

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.

Hypothesis 1

• When the average of total nitrogen increases, the average of BOD increases.

Hypothesis 2

• As QHEI increases, ICI increases.

• As QHEI increases, IBI increases also.

Hypothesis 3

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

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.

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.
