DandyDon:I think Mr.DelGagdo at the Visitors Center would be the one to ask. I was going to call today, but got sidetracked. Work is such an imposition.
I'll try Monday....
If we can get permission to dive Rock Lake I'm going to be finishing Decompression Procedures and Advanced Nitrox w/ Chad September 29.
I'll try to call again on Monday and ask for him. I also did some searches on google and came up with a phone number for agua negra ranch. I may give them a call as well.
