I never knew of muskie being in the lake proper.

The tailwaters and tribs of Barren yes. Drakes Creek is chock full of them from the dam in Franklin downstream to BG and upstream of the dam in the resevoir in Franklin.

They are also in the upper Green. I would assume some must be in the lower Green but KDFWR doesn't report on them there.

Here is the 2011 fishing forecast > http://kyafield.com/pdf/2011fishingforecast.pdf

I have caught them in Drakes on crappie jigs, Bandit crankbaits, and texas rigged worms.
