Haven't seen any evidence of winterkill other than one dead carp this spring that was floating when the ice melted.

BG - 2-3" (2009)
LMB - 4-5" (2009)
WE - 5-7" (2010)
Grass Carp - 8-10" (2009)

I believe there are a couple of full-sized crappie in there as well. Less than 10.

The water is muddy enough that you can't typically see more than a foot. Last spring I did see a couple of the bass.
