I stopped up there last week a bunch of guys fishing it. Don't know how they did though. I heard they put some Walleye and Musky in there I didn't hear any one catch any though.
according to their web site..........
Fishing: The common fish in the 250-acre Gouldsboro Lake are bass, pickerel, yellow perch, catfish and sunfish. The lake also has muskellunge, walleye, crappie, sucker and fallfish. An ADA accessible fishing pier is near Parking Lot 4.
