How healthy is the Rocky River Watershed?
Background InformationRuns through Cuyahoga, Lorain, Medina, &
Summit Counties Located in Northeastern quadrant, near
ClevelandSeven Major Tributaries: Plum, Blodgett, Baldwin, Abram, Baker, Mallet, & HealeyDrains into Lake Erie
Sophia’s HypothesisWhen the QHEI (habitat quality) escalates, the
IBI (fish diversity) will escalate with it.
This darter is from Big Darby Creek, where we went this week.

Liz’s HypothesisAs ammonia levels increase in the Rocky
River Watershed, the IBI, which is fish diversity, will decrease.

How can YOU help?Be cautious of what you use when you deice! Some
salts will run into the river as ammonia. Ethylene Glycol and Propylene Glycol are eco-friendly choices.
When you paint around your house or wash your car, be careful not to dump it into the storm drains.
Restore the riparian zones so they can keep the pollutants under control.These practices will keep the environment balanced
with the economy.
How healthy is the Rocky River Watershed?
