Casa Cenote is situated a few kilometers north of Tulum, and was not in the destructive section of Dean. However, the coastal areas do get knocked around. So, whilst most of the cenotes had no impact whatsoever, the brackish water cenotes, right on sea front, do get alot of run off. As You can see, it is not always water and silt. The water is still murky, quite far back in the cave.
