Potomac, North Fork of South Branch

I joined AW specifically to add info to this stretch of river. Ran it at 1080 cfs and I can confidently say at this level there are about a dozen class IV wave trains.

The ledge seen in many pictures tossed two paddlers in my group of three, and one was very experienced. Once you start seeing the rock formation behind you after a bend, be sure to go left on this upcoming ledge.

I'm not sure who posted that you should run this anywhere above 1100 or so. This run was the site of some pretty hardcore paddlers in the 70's so I wonder if the rapids and water levels were defined by those who didn't want to characterize a major tributary as too tricky.

I believe it's a class III at much lower water levels.

Pour-over: if you use the designated takeout, walk along the banks until you see the 5 ft pour over. To avoid this later, find the middle channel in the river (the pour over is in the rover left channel).

Lastly, I don't think the boulders in the other poster's pictures are along this run, but rather further downriver.
