The Ark has been holding at a perfect flow for the 1 1/2 Wave on the Numbers for over a week now. If you like a big, really fast wave, definitely check this thing out. Stay for a ride or two or a whole session. Just front surfing it is super fun. This video is at 2,800 cfs on the Ark Below Granite gauge:

The best set up at 2,800 for blunts and other moves is to carve around on the surfer's right shoulder, get up nice and high, scoot surfer's left and throw off your very first bounce. Have fun and be aware that there is a pourover maybe 100 yards (?) downstream in the middle. You'd have to miss a few rolls to tangle with it.
