GIS lines vs. surveyed lines in Dunn County

How Dunn County deeds describe boundaries
Wisconsin uses the Public Land Survey System: acreage near Elk Mound is commonly described by section, township and range, where a full section is about 640 acres. On a subdivision lot near Rock Falls, the recorded plat named on the record lists the dimensions, and that plat is the document to pull.
