This is pretty helpful for being prepared. I would also recomend a day on Friday Creek. The grayling and the trout can be incredible. We actually camped there for two nights so we could spend an entire day hiking the creek. Very high water made for an interesting trip.
Some rapids become easier in high water.
We started at the midpoint and had no real problems. Basically you need to know what to expect and scout rapids first. When we floated there were only the two previously mentioned rapids to worry about. We ran the first one with no problem and no choice, the water was too high to line through. The second one we lined.
