Visit Mercer, WI

From the vast water wonderland of the 14,300 acre Turtle Flambeau Flowage to the far-reaching wilderness of the 74,500 acres of public forestland, Mercer offers authentic outdoor adventures that you will remember long after you?ve returned home.

Whether you choose to explore on snowmobile, ATV, car, camper, bike, boat, skis, or by foot, you are sure to discover the unending, unique fascination of the Northwoods.

Every season offers a new way to experience our natural beauty. The quiet of winter snow is broken by the sounds of spring peepers that fade as the loon?s calls fill the lakes in the summer. Finally, the woods explode in a riot of color in autumn and then the cycle begins again. That?s the beauty of Mercer. You can?t go wrong... life is outdoors.

Beautiful, quiet lake with plenty of loon activity...and bald eagles now! Good variety of lake structure - sand/rocks, pads, cabbage weed, grass and muck bottom. Water clarity was about 8 feet.

Ditto the small pike and teeny panfish. Stunted lake so alot of action if your fishing with kids. Heck, tie a little fly on the end of a line and set it in the water and walk 10 feet down a pier and you'll have a bluegill. no pole required.
