I was about to post the same question about the North Rim, where I'll be hiking this weekend. The Wilderness Conditions page hasn't been updated since July 6th: http://www.nps.gov/yose/planyourvisit/wildcond.htm But back then, they said early July conditions were more like late August conditions, that seasonal creeks are dryer, and small named creeks may also be dried up. I hope we see an updby jaybee - Backpacking and Hiking Yosemite and the Sierra
