Dove the Offset mine on Sunday and had the place all to ourselves. Visibility was amazing - easily 30 feet. Best I have seen in Missouri. The surface temp was 75 but the thermalcline was at about 12 feet where it abruptly changed to 50. At about twenty feet it was about 40 degrees. Definitely happy I dove the drysuit. Plenty of fish, underwater rock formations and macro algae that looked like it went for miles. I spoke with the caretaker and he said the normal crowds don't show up until Memorial Day, so I am going back this coming weekend. All this and it's only about an hour and fifteen minutes from St. Louis. If anyone is interested, feel free to email me about going - bsigmund0359@nospam.yahoo.com. Obviously remove the nospam from the address. Two pictures attached.
