Iron County is home to the Turtle Flambeau Flowage. If you are looking for a more remote fishing trip without having to drive all the way to northern Minnesota or Canada, this area might be the destination for you. The Turtle Flambeau Flowage is the big draw here, however, there are plenty of smaller lakes in the Mercer area to fish as well. The water up here is murky in many of the lakes, so plan on using a lot of brighter jigs or lures when fishing here.
