If I had to pick one spot to hook a musky I'd pick Little Wilson Creek. I've had a lot of unintentional musky hookups there and like FIL mentioned most of them has been on spinnerbaits while bass fishing.

I personally would not try fishing below the dam from a boat for a while. The lake is above summer pool now, that plus the rain we've been having lately means who knows what the COE will do when it comes to opening and closing the gates. Two gentleman lost their lives there last fall while hunting from a boat.
