The lay of the land in Poweshiek County
Parcel searches in Poweshiek County tend to center on Montezuma, the county seat, plus Barnes City, Brooklyn, Deep River, and Grinnell. You'll also find unincorporated communities, among them Carnforth, Jacobs, and Tilton. The county was organized in 1843 and named for Poweshiek, Meskwaki chief, so some tracts carry a long chain of deeds. Poweshiek County covers about 585 square miles of land; its 2023 population estimate from the Census Bureau was 18,453. Most of the land area is agricultural or wooded, and the parcel lines get bigger and more irregular as you move away from Brooklyn.
The Poweshiek County economy in brief
The Census Bureau's County Business Patterns counted 572 business establishments in Poweshiek County in 2022, and the largest groups were construction, retail trade, and health care and social assistance. Measured against national shares, agriculture and forestry support services, plastics and rubber products manufacturing, and machinery manufacturing are overrepresented in Poweshiek County. Timber is part of the land story around Hartwick, so a wooded parcel's value can hinge on when it was last cut.
Reading property lines on the Poweshiek County plat map
Parcel boundaries on the Poweshiek County viewer are drawn to keep tax accounts straight, so small offsets from the true line are expected. Rural Poweshiek County land sits on the federal survey grid: a deed might call out a quarter of a numbered section in a given township and range. For a fence, an addition or a dispute in Poweshiek County, budget for a licensed survey; it's the answer a court or a lender will accept.
Acreage and vacant lot search

- Scan the imagery around Tilton; open fields and woodlots with no driveway stand out right away.
