Albert Shoals is runnable above 200cfs and becomes fun at 300 or 400cfs. The primary route starts on the far right side and works its way down through terraced ledges and chutes all the way to the far left. It's quite satisfying, especially if you manage to avoid getting hung up on the moraine of junky rocks that litter the runout at the bottom. Above 2,000 cfs, the speed of the current and the size of the holes to skirt bump the difficulty up a notch to III+/IV.
