Scanning Update
As of August 18, 2014 all "M" number surveys and approximately 94% of "S" surveys are available on-line in PDF format. It is anticipated that "S" number scanning will be complete by the end of the year. Please note that a small percentage of maps, due to legibility, durability of paper, etc. have/will not be scanned; in those cases on-site inspection of the original will be required.

Thank You

Thank you to all who participated in the recent priorities survey.

About the Surveyor's Office

The County Surveyor reports to the County Administrator and to the governing Planning and Development Committee.  The Surveyor is a voting member of the County’s Land Records Committee.

Rock County consists of twenty townships.  In 1833 Lucuis Lyon surveyed the southern boundary, which is the Wisconsin, Illinois state line.  In 1836 the final township was surveyed.  From 1840 to 1975, the County Surveyors’ position was elected and in 1975, the County Board changed it to an appointed position. 

The original government surveyors and their field notes may be found at the Wisconsin Commissioners of Public Lands.
