1892 Map of Oconomowoc

Genealogists and local historians can trace early village cores such as Delafield and Stone Bank, or identify vanished stops like Lakeside Station. The terrain is marked by significant elevations, notably Holy Hill in the north and Government Hill further south, providing a detailed look at the region's topography before modern development. Notable water features such as Nagawicka Lake, Pine Lake, and the chain including Upper Nemahbin Lake reflect the complex hydrology that shaped these early Wisconsin townships.
