Thread: Is this a thermocliine or something else?

Over the summer it was higher in the water column, around 18-19' or so. Maybe the cooling water temps have pushed it lower as the lake gets ready for turn-over? This line was actually a little deeper out more in the center of the lake.

In other areas of the lake, I did see fish right at that line and even a little below it. I got a few light nibbles but didn't hook any to see what might have been holding so deep.

I was drifting slowly with the wind when I took this picture.
