We did it last weekend. The gauge was swinging from 1100 to 800. Looks like the bottom dropped out. Its hard to believe that it dropped that fast with the heat. I'd say it could be run with a lot less water than we did it so it might still be doable. We noticed that it didn't start rising until about 3:00 or so. If you get on it just before dark it should be higher than mid day.
No bad wood to speak of. One log in the crux in the inner box, but it looked like it improved the drop at the level we did it at.
For approach you can take 2 routs - the high road and the low road.
Go through the town of marble and start the easy 4x4 road up the hill. In a sharp left bend you reach a hidden fork in the road. Right to the town of crystal is the low road. Left is the high road.
Low road: This is rougher with more rock crawling and sketchy drops offs (almost as exciting as the creek), but shorter. Dive down past lizard lake, down to the crystal, through the town of crystal (in low range most of the way for 4 miles). After crystal wind up a steep hill past a crux spot and take the left fork (right goes to the south fork). Crawl around a sketchy corner and drive up the NF. When you reach a patch of pine trees, youre at the beef (the runnable beef).
High road: Smoother, longer, way more switch backs, exceptional scenery, takes just as long if not longer. Drive past the fork up hill. Make a stream crossing to the right, wind up over the pass, drive down into NF valley (Lead King Basin), drive down the NF. You can't miss the first drop. All road side (or jeep trail side).
Have fun. Run lots of laps on the upper 4 (boater cross maybe?).
