So we started diving a quarry that filled up in the late 1960s. According to the owner only two other people have ever tried diving this quarry (it was too dark and cold so only one dive). The quarry is said to be around 80' deep, but we encountered a dense algal cloud at around 50' that makes it dark and less than 1' vis at 55'. Surface water temp is around 78 degrees with a 22' thermocline below which the water is 58 degrees and 45 degrees at the algal cloud. I call it a cloud because there are "puffs" of algae that look like round rocks or like your descending into the tops of clouds. We will make another attempt in a couple of weeks to descend to the bottom of the quarry. The question is based on anyone's experience with other quarries, should the algal cloud clear up at some point before reaching bottom at 80'?
