I dove for the first time at The Blue Lagoon this week. It's just north of Huntsville and has a reputation for having pretty good visibility. Boy, did it deliver. There are actually two lakes there and they're old limestone quarries. The visibility in lake one was 30' + all morning. On 9/29, water temp was 82f and my deepest depth was 28'.
