Abri there is a number you can call but I will tell you I was there last Sunday and it had a bunch of water and mud. I can only imagine how it is now especially being so close to the river. Be safe. Call them.
I went with a group after Zeta and some parts of the trails were closed but the cave was not obstructed. The cottonwood tree path was flooded however.
We were there right after Zeta and Yadkin got up over 20 feet and there was no problem seeing the caves. You could see where the water came up down by the kayak area but we had no problems.
