I was there last weekend and the range was still flooded. If the water has not drained, I personally would look for another place or bring your shrimp boots because it was a mess.
Went out there this morning, it was my first time out there great people and really nice range. I joined for the 65 a year membership.
As far as the status still pretty nasty down range lots of mud. Once you go out past the 10-15yd mark gets pretty sloppy and anything past 50yd theres still some water so bring your shrimp boots as previous post stated.
