We ran the Narrows on 4.24.09 It was great fun once you hit the confluence but getting there was a grind to say the least... (6 to 7 hours of dragging, scraping, or walking your boat down)
Two in our party of four put some large cracks in their boats during the run and we found the info available from the park service to be less than consistent.
I was told we could camp in the narrows on the phone with a ranger, but the backcountry desk wouldnt let us camp anywhere in the narrows. Permits were all FREE and the 15 ft. falls was runnable, all four of us ran it and it was killa!
Sinawava down is the gnar of the lower river (below the narrows). Yes, it is well below the confluence with Deep Creek. The rapids dont start until you hit the court of patriarchs and be sure to scout from the bridge that is well off the road at court of patriarchs. This was the only section we didnt scout due to the fact that it wasnt roadside and it was the rowdiest (Satans Staircase)! Top notch whitewater if its running.......
The road to Chamberlain's Ranch was in great shape, and though we had 4wd we didnt use it. flow was a bit below 300 cfs that day and it was going down. I heard the guy at the desk say they werent going to issue boating permits past today, 4.26.09
If you havent done this run already this year you may have missed it.
Contact Zion Ponderosa lodge for current road conditions, if you can, try to get in touch with Cowboy Ken (a local mountain lion hunter).
