55 seems about right. Main lake gets more wind. Also, the water's colder underneath than shallower water of more protected drop-offs. Back in late August, we marked fish as deep as 33 feet--one anyway, as I remember--on the main lake. That surprised me, especially with this summer's heat. I wouldn't rule out a spring down there, but I was not under that impression, and the bottom depth was at least 40 feet.
