Local government in Onalaska handles things like zoning, permits and utilities inside its limits, but the county runs assessment and recording. Land beyond the town limits near French Island generally falls under county rules instead.
Reading the legal description

A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near French Island can be irregular.

Using it on a phone

Who the record really names
Out toward French Island, the owner field shows who the tax bill names, which may be a person, a trust, a company or an estate. "Estate of" on a record near Bangor usually means title hasn't passed yet after a death, and the executor handles questions.
