Ran the updated Granite Springs rapid on 9/6/16. We ran early morning - 8:30 - and the flow was close to 10K. At this flow, the rapid looked very similar to a reversed Crystal - without the dreaded rock island at the end.
Two offset holes, one after the other, in center toward top. Both can easily flip a boat. Huge breaking laterals coming off of the far right shore (bedrock?) with a nasty pour over immediately downstream. The tongue lead to a wave train with a very large pulsing wave about 3/4 of the way down. One boat hit this and reported a "Lava-like" crashing wave. Running down the left shore required breaking over some strong laterals and the run-out is through shallow water. I expect the rapid to look similar at lower water, with stiffer pour overs in center, but perhaps friendlier through wave train. No guesses at higher flows.
Scout left, but be aware that the cobble is still loose and moving under foot.
Hope this helps you all. Be safe.
