donblume:David, No, on Powell or Mead, I have had only 3 dives since OW cert. We had a boat docked at Lake Powell for 3 years and it is an awsome place. I often wondered what it was like to dive there. Sometimes the water had 8 to 12 foot visibility. Odly enough, then (1999) at the slip, the water under our boat was 150 feet deep. Some docks were 250 feet deep. All this, before the lake levels dropped 150 feet. In other lakes (mountain) the visibility is very poor. In my first open water dives for cert. the visibility was at best 2 1/2 feet. I am looking forward to more warm and clear waters to dive.
Lake Powell is awsome. They say you could spend a life time exploring all the nooks and crannies of that lake. Didn't realize fresh water vis was so bad, I've only dove salt water.
