Gentleben,
Crappie had been starting to pick up a bit on Grand the last couple of weeks, but seem to have slowed down since this warm/cold unstable weather. At least that is the way it has been in my dock. I fished last weekend and cleaned some nice fish, and this weekend it was a good thing there was some turkey leftovers.....
You might read a little on this sight, they usually keep up with what is happening in the upper lake area....

Hope that helps ....
