I have a day hike permit on 8/1, and today I went from the TH to Lone Pine Lake just to check that portion of the trail out. I had no problem with the creek crossing -- if you are careful and have a good sense of balance you should be able to get across and keep your feet dry. If you have GTX hiking boots you could just walk across in the water and not worry about stepping on the rocks to keep your feet dry.
