Counties: Union, Marion, Logan, and Delaware

Located in central Ohio.

Surrounded by an agricultural environment.

Largest City: Marysville

Main Water Sources: Scioto River, Bokes
C
reek, and Mill Creek

Used as drinking water for
M
arysville and Columbus.



Location


N
utrient
enrichment from nitrates
and phosphates


Others are siltation and habitat alterations such as
channelization of the river.

Impairment

A
s QHEI (the quality of the habitat) increases, the IBI
(diversity and health of fish) should increase.


Clear water, riparian zone, cover, cool temperature,
substrate, and meanders.


Fish with good habitats have many of their needs
met.


When ammonia and nutrients are high, the fish
population will decrease.

When the substrate quality increases, the ICI
(diversity and health of macroinvertebrates) also
increases.


Usually when the substrate is rocky, there is a larger
ICI. If the substrate is full of sediment, the ICI is lower.

When dissolved oxygen (DO) is high, so is the health
and diversity of the fish (IBI).


DO is important to the IBI because it allows them to
respire. Without this the fish would be smothered to
death.

rinking water for Columbus and Marysville


Agricultural industry sometimes clears too close to streams


Runoff leads to sedimentation


N
itrates and ammonia lead to nutrient enrichment, which leads
to increased algae growth and less dissolved oxygen


Runoff from industrial areas can increase the chemical oxygen
demand


Farmers can use conservation practices

Why is this Important??

Turbid Stream

This is an agricultural
field. This farmer is
being conservative
and using strips of
grass in between
crops to stop run off
