Public Land Survey Records

Original Field Notes and Plat Maps

1800's survey notebook with a town maps in the background that was produced from the survey notes. The field notes and plat maps of the public land survey of Wisconsin are a valuable resource for original land survey information, as well as for understanding Wisconsin's landscape history. The survey of Wisconsin was conducted between 1832 and 1866 by the federal General Land Office. This work established the township, range and section grid; the pattern upon which land ownership and land use is based. The survey records were transferred to the Wisconsin Board of Commissioners of Public Lands after the original survey was completed. Since that time, these records have been available for consultation at the BCPL's office in Madison, as hand-transcriptions, and more recently on microfilm. Now, they are available via the internet as electronic images at UW Madison Digital CollectionsExternal link icon indicating link will open an external website in a new tab.
