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.
