gills range from this years hatchlings to about 8 inches....average being about 6 in...the lake is relatively small...guessing maybe 50 acres...but i have no clue how close that is to being right... as far as trout stocking goes...they stock all sizes. they've put some in at 6 pounds and then we one this year around 8 inches...so size definitely vary....im pretty sure the bass have plenty to eat...every fish we catch is healthy but not obese...i think the main problem may be that an 11" bass doesnt make a very large fillet so most people throw these back and keep the rarer 14" fish.
