I don't think the gate's open from HWY160- call 4Corners in Durango and ask, because it should be opening any day now and they have sources that might give you a heads up. In fact, I'm guessing that that's what rg5hole might have been alluding to when he mentioned Sunday.
Given that there's very little play and its 20 miles, creekboats are highly recommended. If you've got a comfortable river runner, that'll be fine for all the rapids on this run.
Scouting the big ones will be pretty obvious, just be on the lookout for a nasty hole on the right channel below Eye of the Needle (shown below in the lower part of the frame) in Lucifer's (upper frame, the two channels and the confluence below):
If you look close you can see something white and nasty in the shadows, far right, just around the rock island- just hug the inside of that right channel and you'll miss the chomper.
