Last time I fished up on Big Creek the lower end was slow. Did go above Walnut Bottoms the fishing was alot better. Caught several small fish. This was early last Spring. Some of my fishing buddies ride in on horse back and fish above the bottoms, they have done well this year. One of the guys caught a 11in. rainbow on a #12 Adam. They told me it was caught above Walnut Bottoms. Good luck if you get to fish up there and watch out for bears. My friends have seen a couple up there this year.
May God Bless You...
