Approximate - nearest available gauge. Use as general reference only.
Grumpy's Ledge is rated Class III+ between 1,200 and 1600 cfs. At higher flows Grumpy's Ledge really deserves respect. To run this rapid clean make a nice controlled peel out from the ramp eddy. Then follow and ride the current to just left of White Face Rock. Beware getting to close to pyramid rock as there is a shallow rock lurking there.
