As of right now the south fork of the Boise river is the place to go and fish. The fish are easy to find and they are feeding alto, the hatches are good there are tons of bugs coming off right now as well. the bugs to look for would have to be BWOs and really surprisingly their are still a few PMDs coming off on the warmer days. if their is nothing going on with the whole dry fly thing. you can always through on a nymph rig and see what you can pull out. I would use a two fly set up with a October caddis nymph on top and a pheasant tail on the bottom. now the fish are easy to find doesn't mean they will be easy to catch.
