Fished it a few times now. Access is very limited.
In my experience, bows in the headwaters/ browns down below. Not worth all the hassle considering other streams in the area. I'm sure big fish are present ( though I never caught one) but surely not in the numbers of other local watersheds.
IMO it's worth a shot if your close. If you gotta travel at all might as well fish some where else, but I've only been there twice fwiw.
