Deeper Lakes Extended Metro or close to cities

[jasondbaker]

Wazee is about 2.5 hours from the west side of the Twin Cities -- and probably more like 2 hours if you are closer to St. Paul and 94.

I don't think there are any worthwhile deep dives in the extended metro region. You can reach several good deep sites if you are willing to devote 10-12 hours to driving and diving. I would recommend: Lake Superior (Madeira), Biwabik (St. James), Wazee, and Crosby.
