We were there a couple of weeks ago; I meant to post this earlier but forgot. Anyway, we ran into several hikers freaking out because they were unaware of the water situation. Water was flowing at Catawba in October. Water is running at a trickle at Campbell out of the pipe (the pipe really leaks bad in many places), but is scoopable out of the spring well. Just make sure to bring a prefilter because there were a ton of dead bugs floating on top..
Maybe the recent rains will help...
