Thanks a lot for the help!

Catmandoo:
The flying trout circus sounds great, at first I thought that you were suggesting that the trout had literally been tormenting you, like physical attacks. Haha, guess I've seen too much 'river monsters' lately.

Thanks for the tip on the sinking phenomena. That makes it a lot easier to give up on the fishing, actually, now I'll switch to a netting tactic. This way I should be able to grab at least one fish (dead or alive) and see how they look. I imagine that they may be showing physical signs of stress by this point, due to heat.

I have lots of pictures, but my only internet connection is this here Android phone. Can't figure out how to post pics with it here? I'd happily email them to someone to have them posted.
