The range is for the rapids of Glendale Shoals and of Little Five Falls; the flat water has no known upper limit
Below Glendale Slide is Lawson's Dawg. At medium flows, this rapid offers a first rate boof. It vaguely resembles Soc-em-Dog on the Chattooga River, but is easier to hit. Some of the river peels off to the right, so you'll have to work a little bit to hit it perfectly. In low water, the approach is a little boney and can kill your momentum, but it's still good to go. The run out is manky in levels under 300 CFS.
At higher flows, this is a first rate rapid. Just be weary of everything to the right of the boof, as it gets scarry looking. Lines open up left of the boof in higher flows as well. The run-out can be a little manky.
