Hi Jighead,

I think Wiskers is right on. I fish mostly on Green and water temps are below what we
"normally" have.
Once the temps fell into the mid to upper 30s the fish moved into 30 feet of water , plus and are holding very tight against the cover.
Not saying every fish it there, because I still experiment and can catch a few shallower, but by and far the bulk seem to be there. At least for my way of fishing.

Good luck to ya and if your ever up this way let me know. Most of my buddies give up when it gets cold and I end up going alone.
