What kind of fish is this

[LlindeX]

Yes, the fish is a White Sucker. Go to your local library and look up books on ichthyology and/or limnology. Any good book on these subjects should have them listed and tell you how to tell the different species of suckers apart. As far as the fish kills, if you continue to see them in any numbers, I'd collect one of the freshly dead ones (or one that seems to be in distress), keep it on ice, and turn it in to the local Dept. of Wildlife office along with a description of what you're seeing and the location. They will usually check things out. You never know, you may have some unscrupulous idiot putting something in your stream of river that doesn't belong there. I know, we've have about five or six cases of that here in Colorado in the last few years. It is getting so expensive to legally dispose of waste products, that some people will do anything to avoid that expense; even dump the stuff in a waterway.
