No access is basically the deal, they will not give any type of permit at all. It's a real bad deal because it's a great run especially at high flows, this april they did a flush and released 5-6 grand for a couple of days and I tried to get access but was shutdown. I even offered the Wind River Rafting Company a $150 per kayak access just to run it during the release but he was not intrested.
I had heard if you buy a fishing permit for the canyon that it gives access but on the permit it mentiones no kayaking.
If your in the area you will want to hit our local ditch, the flow is 1200 and it's going to hold that level untill October 15th. Also if your coming this way all of the clarks fork runs are really good.
