The County Surveyor reports to the Planning Director and to the governing Planning and Development Committee and is a voting member of the County’s Land Records Committee. The Surveyor’s office is responsible for maintaining Rock County’s survey records and the County PLSS Survey Monuments. The Rock County Surveyor does not provide private land surveying services for the public, so please contact your local surveyor or visit Wisconsin Society of Land Surveyors for assistance with these services.

Rock County consists of twenty townships. In 1833 Lucius 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.
