•The Upper Great Miami River is located throughout several counties. Including: Auglaize, Hardin, Mercer, Champaign, and Logan
•There are 245 total stream miles
•117.4 miles of the stream were assessed

Kristin’s Hypothesis
Hypothesis: As the Total Suspended Solids increase the QHEI (quality of habitat) and the ICI (diversity of macro-invertebrates) decrease.
![Page 5: Upper Great Miami River](https://reader035.fdocuments.in/reader035/viewer/2022062321/56812bb3550346895d8ff0c3/html5/thumbnails/5.jpg)
Data Analysis
As TSS decreases, ICI and QHEI increases.

Conclusion:
• The Total Suspended Solids cover up the macroinvertebrate’s habitat.
• Since the quality of their habitat decreases, the macroinvertebrate’s population also decreases.
• My hypothesis was supported

Chenoa’s Hypothesis
When the substrate quality decreases, the QHEI also
decreases

Data Analysis: As Ag. and Forest increases, QHEI decreases.

Conclusion
• Agriculture within 90 meters of the river can lower the QHEI.
• When farmers work the land at the edge of the stream, pesticide run-off kills sensitive fish, which lowers the QHEI, which in turn lowers the IBI.
• My hypothesis was supported.

Megan’s Hypothesis
As DO (dissolved oxygen) increases,
so will the IBI (diversity of fish).

My graph shows that as the DO increases the IBI also increases.

Conclusion• The Upper Great Miami
has very good DO with a healthy fish community
• Fish cannot live without oxygen, so therefore the IBI depends on the DO
• The DO is important because fish that are sensitive will not live in the creek/stream if there was low DO
• My hypothesis was supported

To Increase ICI, IBI, and QHEI
• Don’t remove the cover (removing the cover would cause the DO level to drop) , rocky substrate, or meander (curves in the stream) from the stream
• Don’t farm within 90 meters of a creek/river
