I just did the first section to Neels Gap with my son this past Thursday & Friday. Water was flowing nicely in all the expected places, and in all of the unreliable places too. As mentioned above, there's a long stretch between Hawk Mt. Shelter and Justus Creek without water. This week, there was trail magic in one of the gaps in this section in the form of several gallon jugs of water. However, I wouldn't count on that. Just get water at Hawk and not worry about it.
I also recommend AWOL's guide
. You can buy it as a PDF and print out only the pages you need. I shrink it down to 4 pages per piece of paper (4 on front, 4 on back) and carry only the parts for the trip I'm on.
Enjoy the trip. Ask away if you have any other questions.
