Yes, that stretch. Put in is a bit easier, we found a spot with about a 25 yd carry to put in.
The whitewater classification system needs revision in my opinion. While I consider the stretch I just floated as class 3, it differs completely from Shoshone at 3000 CFS Class 3 which in turn differs from every river. So, I hear ya, descriptions of runs can be difficult to quantify with our antiquated system.
Here's a better description.
In my raft we had a rookie rower and two veterans. The rookie rowed the lake.
I would NOT take my 2 and 4 year olds on this stretch, but I did take them down the Dolores from Bradfield to Dove Creek and the entire slickrock section. I also felt comfortable with them doing cemetery rapid at about 3000 CFS on the roaring fork. (all of these supposedly have class 3).
If you swam without a PFD, I feel confident in saying you'd die. If you swam with a PFD and did not go back to the boat, I would not like the odds of survival.
Continuos, fast and no eddies. However, at lower flows, the danger would be minimal- other than getting stuck on a rock.
I say, lets change the whitewater classification system!
