Dove a portion of the Yough River this last Sunday. I went with 3 other dive veterans (3 dive masters) from a local scuba club and and we entered the water at 10:30am and got out around 12:30pm. As the current was relatively strong, the current carried us at different speeds down the lake.
It was basically a drift dive and all 4 divers didn't get to see other till the end of the dive. The day was perfect for lake diving with about 6ft vis. I drifted down the lake pushing against any rock I encountered. We used 7-5-3mm suit (no hood, no gloves).
There were a lot of 1-2ft fishes (bass, catfishes) following us around (they get really curious and come as close as 5inches from your dive mask looking at you face to face and opening their mouths wide to show territorial instinct.
I dove close to 2 hours using 2500psi air (I don't breathe :). It was pretty shallow with max depth of 20ft. I overshot the landing area by about 200ft so had to swim the lake upstream against the current. Final departure site was Hazelbakers on Layton road.
All in all, a nice dive to practice buoyancy, presence of mind (essentially you're on your own) and navigational skills.
