Difficulty rating taken from Texas Whitewater. Distances and gradient measured using GIS tools in 2015.
There is no longer a gauge on the Johnson Fork of the Llano. The range of recommended flows is only a guess, based on the fact that the cumulative drainage of the other forks at Junction is about 6-7 times greater than the drainage of the Johnson Fork.
