BALL BLUFF Lake lot. Why have a lake lot on a lake when you can have a lake lot with land on 2 lakes. Ball Bluff Lake and Little Ball Bluff Lake. A great lake to fish or for recreation. Known to be a walleye and crappie lake. This is one of the cleanest clearest lakes in Aitkin County. Lake depth 78 feet and has a boat launch area on the west side of the lake. Homes are far and few in between on this lake. That makes it nice and peaceful. Close to other area lakes and the Mississippi River. Just 30 minutes to Grand Rapids and an hour to Duluth.
