The Butler Run starts right away with no warm-up. You'll paddle right into Butler Ledge from the put-in pool. A bit of a misnomer this is not a classic ledge-style rapid but rather a long rapid over a boulder bar with one plunge over some large boulders that makes that feature reminiscent of a ledge. The rapid continues past a large, picturesque white boulder before a brief pool separates it from the next rapid below.
There's a great surf wave at the white boulder (1200-1500 cfs is optimal) and a second good wave at the pool at the bottom (2000-2500 cfs is optimal). Usually both waves are not in at the same flow.
