Treasure Island is the largest island on Lake Waseosa. Zoned Conservation, it is a contained slice of undeveloped land comprised of 3 parcels. The larger eastern parcel is separated from the smaller western parcel by a narrow strip of public land. A few years ago, the western parcel was sold for back taxes to the owners of the western parcel. They now want to change the zoning to permit development, a move opposed by the vast majority of area residents.
