The Tubes

The Tubes is a railroad bridge with three arches. This bridge is quite dangerous because of the ever-changing accumulation of strainers.
The main current usually funnels into the middle tube, which is usually clogged with debris. BE VERY CAREFUL HERE, SCOUT THOROUGHLY AHEAD OF TIME.
The left tunnel is the most difficult and most interesting. Immediately after this bridge is a river-wide, 3 or 4-foot pourover.

Wade Bowman contributes:
"This is an extremely technical section, and the water is extremely shallow for a long distance following the tube, which is something foot scouting will not reveal. When I say shallow, I mean about an inch of water (at a high level), and it moves very fast. Be sure you are on balance and prepared after the first drop, before entering the tube. Being on edge or out of your boat would be a disaster at this point."

Between The Tubes and the Williams Street bridge is only one interesting river-wide ledge drop. River left is a slot with a large rooster tail. Sneak just right of the roster tail. At very high water, you may bypass the slot on far river right, over a pourover. Immediately before the Williams Street bridge there is a nice boofing rock in the center of the current. It has a large pillow in front of it.
