first which three mile are you referring to, unfortunately there are a few. Is it the one close to the town of Windermere or Rosseau?
if so, there is no pike in the lake, good sunfish, perch and rockbass populations. bass and walleye are the 2 main species in the lake most people target. i have a cottage up there but never seem to venture into any of the backlakes. i probably should start to.
