Rocky River Watershed
Is this watershed healthy or unhealthy? If it is unhealthy, what are the main impairments?

My hypothesis is that when the DO (Dissolved Oxygen) in the Rocky River increases, the IBI (Index of Biotic Integrity) also increases.
As the QHEI (Qualitative Habitat Evaluation Index) increases the IBI (Index of Biotic Integrity) will increase at the same rate.
QHEI vs. IBI
As the QHEI increases the IBI will increase at the same rate.
When a river has a rocky bottom, and lots of trees around it, you have happy fish, because:
When the health of the substrate increases the ICI or macroinvertebrate community increases in numbers also.
