The Henrys Fork- I have not been fishing it lately, the water temps are too high on the lower stretches. But towards the end of June and the beginning of July it fished well. Streamers were the ticket for most trips, although I did run into some epic pmd, caddis, and drake hatches that produced consistent fishing on top.
Here are some of the goods.
And here are some pictures of some other fish from the area.
