I tell you what, that is one tough place to access. I've explored it in my EWU days, but I found that the access is just too weird and tough, and I didn't catch a thing the places where I could access. There are trees all over the sides of the canyon and over hanging in the lower canyon to a non fishable level in many areas. The upper canyon seemed like there was fishable water in the middle, but getting out past the marsh and lillies was just to hard, you need a floatation device just to help you walk, every step you just wait to keep on sinking! I'm sure there is some sort of fish there, but the access is just not worth the fuss. You will see what I mean when you go. I've spent many days chasing fish out that way, and I only went there once because of the funky access. Ticks,

I don't miss them at all.

I would not go there during tick season. Being hot and sweaty and frustrated because of the lack of fishable water is enough.

I would say if you go, the lower river is the place to access easier and it looks more like a fishable stream instead of a weird marshy slow moving frog stream. My 2.
