I am not sure what is running, but I think most stuff up there is still going. Gros Ventre,slide lake to bridge campground, III+ to IV is north of Jackson, and is 3 miles long. Bitch creek, hwy 32 bridge to france boat ramp, is 13 miles long and is III/IV with 2 V's which are supposed to be easy to scout/portage. Greys river, Squaw Creek to bridge campground, 2 miles long III/IV. And Granite creek, granite falls to hoback river 4.5 miles, class III.
You can buy a little pample called Jackson Hole Areas Floaters Guide at any of the local kayak shops. And it has directions, and short discriptions of the runs. Have fun.
