Isn't this fairly typical for this time of the year? I have been coming down to the lake around the 1st week of April for quite a few years. Last year it was flooded and the lake dropped quite a bit just before we got there, the year before I think parts of Hillman Ferry campgound where we stay was flooded at the end of March and the water was still falling when we got there. I actually think it's been pretty much the same forthe last 3 years.
I think Wiskers advice is excellent. Folks those fish are still there and as Wiskers said, look deeper. I'd be looking in the 8'-15' debth. Keep moving they got to be there somewhere.
I know its tough when the water fluctuates, they've dropped our local lake over 20' in the last week. Unfortunaley its all coming your way.
