Great Miami Loramie Creek
By: Kathryn Reed, Xiaojing Wu, and Sarah Ambach
Location
• Located in Western Ohio• Mainly in Miami and Shelby
Counties• City of Dayton is at southern tip
of watershed
Background info
• 353 miles of stream• Contains Lockington Dam
(habitat and flow alterations are damaging
watershed)• Mainly agriculture• Farmers working to improve riparian zones • Bonuses given to add filter strips, plant
riparian zones and add fencing for cattle
The yellow is row crops and the bright pink are cities like Dayton, Piqua, and Troy.
First 2 related, both due to channelization
Nutrients = fertilizer
Siltation results from channelization and construction
Hypothesis #1
As the QHEI increases, the IBI also increases.
=
Analysis *QHEI and IBI are directly related.
*In 1982, QHEI increased and IBI didn’t
*Troy may be causing runoff and point-source pollution causing IBI to stay the same as QHEI increases.

Conclusion
Habitat quality (QHEI) such as riparian zone, substrate, and meanders greatly affect IBI.Fish need clean water, High DO, and food to survive. Great habitat will bring more fish diversity.
Hypothesis #2
• As the percent of agricultural land use (within 90 meters of the stream) increases, the IBI decreases.
=
Where’s my friend Nemo?
• Inverse relationship • No significant discrepancies• Agriculture (within 90 meters of the stream) adds
nutrients (fertilizer) which hurt fish (IBI)

Conclusion
• Agriculture intrudes on the Riparian Zone
• Nutrients (fertilizer) and soil run off into the stream
• Causing an increase in siltation which destroys the fish habitat
Hypothesis number 3
• As the quality of the substrate increases the IBI also increases.

Place and TimeSubstrate is a component of the QHEI
IBI and Substrate quality are directly related
Siltation was a significant impairment –Causes low substrate quality

Conclusion
• IBI depends on the substrate to be clean and free of siltation
• If substrate is full of siltation (not clean) the IBI decreases
• When substrate is full of silt fish don’t have a place to lay eggs or hide from predators
What Can We Do To Help?
Urban
Stop point source pollution
Slow down construction
Keep streets clean of oil and gas
Agriculture
Plant riparian zones
Keep cattle out of streams
STOP channelization
Suburban
Stop washing Detergents into sewers
Stop fertilizing lawns
Slow down construction
Conserve!!!
