OTTER LAKE, Eagle River Chain of Lakes, Wisconsin. The Eagle River Chain connects to the Three lakes chain of lakes forming the largest freshwater inland chain of lakes in the world. Boaters have access to 20 lakes and another 8 in the Eagle River Chain - connected by the Burnt Rollways Boat Lift. This property features 5 beautiful acres with 300' of sand shoreline, with a permanent dock. You'll have your own boat landing, and boathouse lakeside. The current owners had a Timbershore custom built home built in the 1970's which has been very well maintained. The home is all cedar with 3 bedrooms, 2 baths. They did an addition a number of years back which gave them a large office on the main level and a great workshop in the walk-out lower level. There is a detached 2 car garage with a storage and overflow area. There are very few, if any, 5 acre parcels (beautifully wooded), with 300' sand frontage, on such a great chain.
