While everything stated above is true with regards to rocks, portages, and the like, R2ing lower clear creek in a smaller raft is a pretty damn good time. Give it a little more flow to pad things out, maybe 400-500, and it's a great level to learn the creek in your raft. Scout the critical areas - elbow falls, screaming 1/4 mile, and the diversion damn - and you should be good. It's all class III with those features layered in to give you a taste of class IV. Don't wait too long the lower flows are prime for learning the lines. Once it gets over 650-750, the creek takes on a different nature and becomes a little more pushy. I R2'd it at about 900 a few years back and, well, giddy-up. To be fair, my partner an I know the lines in there extremely well, as it is the backyard ditch.
