Townships organize a lot of rural life near Altamont, from road upkeep to how land is described, and a Deuel County township map displays their lines. This guide covers the free Deuel County, SD options and how to read them.
How to use the Deuel County township map
Where civil townships exist in the county, they are named local units, and their duties near Clear Lake depend on South Dakota law. Rural land in Deuel County comes from the Public Land Survey System, where a boundary survey township is about 6 miles square, divided into 36 numbered sections.

Seeing township lines on the Deuel County map
On the Deuel County parcel viewer, the parcel record for a tract around Astoria typically lists the township, and many viewers draw township lines as a layer. For the survey grid, look for section, township and range in the legal description on the Deuel County record.
How the survey grid is numbered
For land around Gary, sections are numbered from 1 in the northeast corner, and the numbering ends at 36 in the southeast corner. Calls like 'NE 1/4 of the SW 1/4' near Goodwin make sense in reverse: locate the last quarter named first, then work inward. Water, old surveys and corrections can leave odd-sized lots along section edges in Deuel County.
Old names and overlapping districts in Deuel County
Older deeds near Altamont may name a township differently than today's Deuel County records, so compare the legal description too. Election maps, school districts and fire districts in Deuel County do not always follow township lines near Astoria, so check each one separately.
