Foam in Creek

Clay particles.

They've never really determined what exactly causes it, but they say it is of no health concern...

That's what they were saying about the Cuyahoga River in Cleveland just before it caught fire!

Call it what it is. It's pollution contaminating the water. Clean water doesn't do that and it certainly isn't normal. It's usually caused by phosphates and other contaminates in runoff/discharge into the streams and rivers.

I guess you guys have forgotten what clean water looks like.

I fly fish high mountain streams with foam. It's caused by decaying organic matter. The matter causes a disruption to the skin or surface of the water creating air bubbles. In the fall, when the aquatic grasses start to die and decay, it's most prevalent. It has a light tan hue to it.

If you find very white foam, it is possible it comes from a man made contaminate.

The creek in my back yard that is mostly spring water never foams.
