Pollution

Reached the Tipping Point

Pathogens

MSD has to post warning signs like these along Floyds Fork due to the excessive pathogen loads.

Waste Water

Floyds Fork receives >4,000,000,000 (that's BILLION) gallons of Municipal Waste Water annually 

Set to increase by 250% by 2040 if no changes are made

Nutrients that Kill

Nitrogen and Phosphorus, while good for plants, are a disaster for aquatic life.  

These excess "nutrients" feed unhealthy algal blooms that deplete oxygen levels within the stream (remember: these nutrients are good for plants but bad for aquatic life)

When oxygen levels are depleted, animals that can't move die. Floyds Fork has a mollusk population (fresh water clams, muscles, snails, etc) that depend upon a healthy stream.  These mollusks are the natural filtration process that keep the water clean for the fish.  If they die, the fish will not live much longer after them.  Two thirds (2/3) of the Floyds Fork mussel species have already died. 

This is how you kill a stream!
