Yes, PeteCz, exactly. I certainly take this seriously. I just want a decision to fish or not based on the best data we have. Without that data, it just becomes a battle of anecdotal viewpoints. We humans often make bad decisions when our emotions become involved in the process. And trout dying makes a lot of people emotional. Some people so much that they join PETA.
Ijsouth, your point seems very reasonable to me. Some streams are obviously in more trouble than others.
