When a parcel crosses a boundary
The county borders Clay County, Emmet County, O'Brien County, Osceola County, and Palo Alto County, and each of those keeps its own parcel map, at least around Arnolds Park.

How land is described here
Iowa uses the Public Land Survey System, so rural legal descriptions near Spirit Lake cite section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though corrections make some sections near East Okoboji Lake odd-sized. Keep the legal description for land near East Okoboji Lake for any title or survey request.
Before you lean on the lines
For a tract near Okoboji, listed acreage is an estimate; only a licensed surveyor establishes the real lines on the ground. For land near Arnolds Park, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
Not the same thing
If you're looking near Okoboji, don't confuse the atlas with a recorded subdivision plat: the recorded plat at the County Recorder is a legal document, while the atlas is a reference.
