Visited Dive Haven today for the first time, and was very pleasantly suprised. Beautiful area, easy to get to (compared to Blue Water or Loch Low Minn), lots of room, picnic tables, platforms (and more on the way), and the Easley family were extremely hospitable.
My wife and I dove the perimeter, max depth on the dive was about 45 feet (but averaged about 25). Average viz varied from 3 to 15 feet (however, I think the water was stilled a bit stirred up from the storms yesterday). We hit the first thermocline at about 18 to 20 feet.
We brought the kids, and they had a blast snorkeling and exploring. It has more of a lush lake feel, then a quarry. The Easleys are obviously working hard to add a number of platforms, and have plans for doing much more, including adding white sand for the kids to swim/snorkel, night dives, camping facilities, etc.
This will undoubtedly become our favorite local dive spot, to keep tuned. It's convenient, inviting, and family friendly. All the scuba dogs in the Atlanta area should definitely check it out.
