Opening the Dubuque County parcel viewer

Reading sections near Asbury
On a grid map of Dubuque County, sections are numbered from 1 in the northeast corner, and the sequence zigzags row by row to section 36. Calls like 'NE 1/4 of the SW 1/4' near Asbury read backward: locate the southwest quarter, then its northeast quarter, on the county grid. Correction lines and irregular sections exist, so a section near Bankston may not be exactly 640 acres.
Township records near Bankston
Older deeds near Bankston may name a township differently than today's Dubuque County records, so compare the legal description too. Election maps, school districts and fire districts in Dubuque County do not always follow township lines near Bernard, so check each one separately.
