A Henry County township map answers two different questions around Kewanee: which local township a property sits in, and where it falls on the survey grid. Here's how to see township lines for Henry County, Illinois, on free official maps.
How to use the Henry County township map
The named townships on a county map are civil townships, and a parcel near Cambridge belongs to exactly one of them. Rural land in Henry County sits on the Public Land Survey System, in which each township is about 36 square miles; each holds 36 sections, so a farm near Nekoma may span two.
Finding the tract on the Henry County map
The county's own public map is the Henry County WTH GIS map, built on a WTH Technology GIS parcel site, and it opens without an account for parcels in Annawan and the rest of the county. Click any Henry County parcel near Annawan to open its record: owner, parcel ID and assessed acreage are generally listed. For a backup route to the map covering Cambridge, our Henry County directory entry keeps the link current.
Seeing township lines on the Henry County map
On the Henry County WTH GIS map, the parcel record for a tract close to Cambridge generally lists the township, and many viewers draw township lines as a layer. Some Henry County viewers include a PLSS layer that labels sections, which helps when a deed near Colona cites T and R numbers.
How the survey grid is numbered
Near Colona, sections are numbered from 1 in the northeast corner, with the count snaking back and forth to 36 in the southeast. Calls like 'NE 1/4 of the SW 1/4' near Colona are read from the end: the final quarter listed is the largest piece. Correction lines and irregular sections exist, so a section near Cambridge may not be exactly 640 acres.
Old names and overlapping districts in Henry County
If a county deed near Nekoma cites a township that no longer appears on the map, the county recorder can generally explain the change. For property tax questions, the township shown on the county record for a parcel near Annawan is the one that counts.
The Henry County economy in brief
County Business Patterns counted 1,037 business establishments in Henry County for 2022, led by retail trade, other services, and construction. Compared with national shares, Henry County leans toward agriculture and forestry support services and museums, historical sites and parks, which shapes demand for land near Atkinson.

Why the township matters
In Henry County, township boundaries decide which local office you deal with, so check the record before assuming. When you compare tax bills for land near Cambridge, check whether the parcels sit in the same township; levies can differ across the line.
