Interesting! I was visiting my dad in Mesquite, and rode my bicycle from Mesquite, up Hwy 91 (which is what the campground is on), right past the entrance. I wondered how the campground was, but being on a 55 mile ride, didn't really want to take the time to look.
We had the Saturday evening wind and rain in Mesquite, also. Half an inch at the house. All but a couple spots had dried on the roads when I was riding (started at 6 a.m.), but the canyon walls on 91 between Mesquite and Littlefield had lost lots of rocks onto the road.
I'll have to swing-through the campground the next time I am heading to Mesquite. Sister & her husband stop in Hurricane when heading towards Colorado, and this may be another possibility for them.
