I'm guessing there will be fish in 5' to 10' tight to brush on the flats (shallower when it warms back up), but they may pull out to the 1st drop near the flats during the really cold days. I'm more worried about TVA dropping the lakes than the temps as it looks like they are only calling for (2) days to be way below normal temps. If they start dropping the lake the crappie will head deeper fast.....too bad I can't seem to catch them worth a darn casting when that happens and I'm not much on the long poles. Weather is pretty much normal for this time of year....doesn't stay pretty for long early April, but the fish gotta eat sometime and the cold won't be around too long. Good luck.
