Granddad Ledge - Center (Right) Line

There is a 'right side' route (center-river at Granddad Ledge) which opens up at mid-range flows. This was run at 1800 cfs, but most likely was also available at 2000 cfs. No scouting was done of this line at 4000 cfs. A large rock in the middle of the landing zone would be of concern for higher levels. See the picture -- the rock could piton and vertically pin a boat.
