Just got back. My suggestion is to try to find some "slack" water where the current isn't as strong and get deep. I didn't have a whole lot of success, myself. But the ones I did catch were strong fighting!
I read somewhere that those were bred specifically to be easy targets for eagles. It was some website dealing with streams in the Cherokee reservation in NC...
Indeed I have been sprayed with police grade pepper spray for training at work and I can tell you ...IT SUCKS WORSE THAN ANYTHING IN THE WORLD It's worse than teargas. It should do wonders on dogs.
