A am relatively new to the area and I went to fish Tanner creek and Warenndale for the very first time. Here is my observation:
Tanner creeek, you have to fish outside the creek's mouth boundary. Places where you are allowed to fish are not very good for plunking, the water reverses itself and flows upstream next to the bank. Only people fishing were throwing spinners and other hardware at the fish! Didn't see them catch anything. I was plunking there with no success. Warendale was a different story, this place was full of plunkers but only two fish caught. They said it was good a few days before (of course they always say that).
It was a scounting trip for me to see how it's done on such a big river. I quickly came to conclusion that I don't have a proper gear to fish there. Not enough weight, rod not big enough etc.
