Made a dive @ Scuba Ranch at Clear Springs in Terrell, TX on Sunday and aside from being a very "refreshing" 58F @ 25 ft, the vis was quite good at about 12-15 ft. Four of my fellow DM classmates and I, along with our instructor, were the only ones in the water, which meant nothing had been stirred around at depth so that definitely helped with vis. And our training platform that's normally around 20 ft had a hard deck of about 26 ft, so the lake is definitely up quite a bit. I got down to 32 ft max depth and didn't notice a thermocline so it's must've been somewhere around the 40 ft mark. I was perfectly comfortable in a 5mm wetsuit with a 6/7mm semidry hood (SeaSoft for use with a ffm), 5mm booties and 3mm gloves. My hands did get cold near the end of the dive and my feet got cold about halfway through due to having drain holes drilled in the soles of my booties but I was never uncomfortable at any point during the dive. Looking forward to the OW class I'll be helping with in mid-January.
