Winnebago County does not publish parcel acreage, so acreage below is measured from each owner's parcel boundaries. That is a close match for deeded acreage — the median of the two agrees where counties publish both — but it is not the deed, and it will differ where a deed runs to the centreline of a road or where several units share one footprint.
