The upper part is but when you get down on the lower springriver where it runs into the current river, black river is outstanding fishing not many places to get to the river and take out. your not going to catch a limit every time but one or two a trip with a 3 or 4 lber and maybe a 5 or 6 you never know. The Eyes are like hunting a big Buck their not everywhere not everyone can catch them unless you go to Canada they have lakes that have nothing but Walleye in them.Been their,Done that.Walleye for breakfest,lunch and supper what a life!!!!!!
