Rogue, North Fork

This run and the two below (Takilma & River Bridge) are summer and fall Rogue Valley staples. In the 9 years I've been boating on this stretch I have never seen it too low to boat. Both Dreamflows and Pat Welch post daily estimates online. The two estimates do vary a bit from each other but the difference is consistent so both work. I'd say below 800cfs the run is easier (solid class 3 boaters should be OK 800 on down) as Karma becomes less pushy and the two holes on the right mid way down disappear. The best way to scout Karma is to stop in the eddy on the right above the 3+/4- rapid leading into it. Eddy out right then climb the right wall and walk to the overlook about 150' downstream for the birds eye view. Even then you'll only see 2/3 of the rapid as the last 8' sloping ledge is out of sight as the river curves to the left. To spot this large eddy; it's on the right before the river will make a 60 degree turn to the left, narrowing down between large boulders with a horizon line just past the boulders. Trust me you'll know when you see it. As of 2011 it is now really easy to spot the eddy as a 1' to 2' diameter log now spans the river just below the eddy as you head into the drop above Karma. Don't count on this log being there next year though.
After Karma the river mellows out until Knob Falls, I go up and over (more work but faster) but most of my buddies opt for the seal launch below the falls. I would go up and over unless you're with somebody who knows where to get out above the falls. This run even though upstream is better at low flows than River Bridge as the channel is more narrow and the water deeper. Oregon Kayaking, Jefferson State Creeking and Dreamflows all have write-ups with pictures of this run
