I highly recommend the Chute of Muddy Creek, this weekend (4th) should be it for a good run. Check the gauge at Emery, if its above 300cfs you should be good to go. I ran it twice this year, both times the Emery gauge said 400cfs, but lots of water is taken out above I-70 for irrigation.
Class I-II, some technical manuevering, but nothing serious. The best low-key float I've ever done...15 miles of surreal beauty. Do it!
