Never fished Belva Deer myself yet, but I`ve talked to a few who have fished the lake, with one returning from there earlier this week from a 4 day outing.
Sounds as though they caught some decent bluegill last Thursday, but Friday with the severe weather and front that moved through changed things alot. Nothing caught after the front went through.
I have been told this lake turns off for a few days after a big rain, course that can be true for most lakes.
