Louisa County at a glance: towns and land
Besides Wapello, which serves as the county seat, the map covers Columbus City, Columbus Junction, Cotter, and Fredonia. Unincorporated spots like Cairo and Toolesboro are worth a look if you want rural acreage near a crossroads community. The county was organized in 1836, so some tracts carry a long chain of deeds. The Census Bureau puts Louisa County at about 402 square miles of land and an estimated 10,513 people (2023). Outside Columbus City the parcels open up quickly into farms, timber and small acreage homesites. On the parcel layer, Port Louisa National Wildlife Refuge shows up as public ground, and the private tracts along its edges are worth checking line by line.

For a fence, an addition or a dispute in Louisa County, budget for a licensed survey; it's the answer a court or a lender will accept.
