Scioto Bokes Watershed
By: Akanksha, Annalese, and
Madison
Counties: Union, Marion, Logan, and DelawareLocated in central Ohio.Surrounded by an agricultural environment.Largest City: MarysvilleMain Water Sources: Scioto River, Bokes Creek, and Mill Creek Used as drinking water for Marysville and Columbus.
Location
Nutrient enrichment from nitrates and phosphates
Others are siltation and habitat alterations such as channelization of the river.
Impairment
As 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.

Drinking water for Columbus and Marysville Agricultural industry sometimes clears too close to
streams Runoff leads to sedimentation Nitrates 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 StreamThis is an agricultural field. This farmer is being conservative and using strips of grass in between crops to stop run off
