Winnebago County, created in 1840 as a territorial county, is named for the Winnebago Indian Nation. Located in
northeast Wisconsin, the county seat is Oshkosh.
Is on the west side of the Lake of the same name, and from its location, has the best advantage of inland
commerce of any County in Wisconsin. Into this Lake flows the Fox, the largest and most easily navigated river in
the State. The Wolf, the main stream instead of the Upper Fox, is also navigable for a great distance, and the
increased business prophecies a large trade to centre around Lake Winnebago. The soil of the County is excellent;
the eastern part, along the Lake Shore, is heavily timbered; the western, prairie and openings. The region along the
Fox is marsh, extending from half to two miles back, and in no case, in its whole course through the County, has it
high banks on both sides, except at Oshkosh. There is some Government land not yet taken.
Oshkosh is the County Seat, and the largest place in the State north of Fond du Lac. It is near the mouth of the
Fox, and well situated to command a large trade. Several steam saw mills are located here, and along the Lake Shore
employed in manufacturing lumber from logs floated down the Wolf.
Winneconne, on the Wolf, at the only crossing place, on account of the marsh, has a good bridge for crossing, and is
a growing village.
Neenah and Menasha, on opposite sides of the Fox, at its outlet, are both places of note, and flourishing. The Fox
is here divided into two streams, by Doty's Island, on both sides of which are falls, creating good and abundant
power, which are partly improved for manufacturing purposes. The Fox River Improvement has its lower terminus at
Menasha. This improvement consists in building canals around some of the rapids, and by creating slack water above
them, thus rendering the whole stream navigable from Lake Winnebago to Green Bay.
The Green Bay district land office is at Menash, and the whole of Winnebago County is in that district.
As reported by the Census Bureau, the county has a total area of 579 square miles (1,499 km2), of which, 439 square miles (1,136 km2) of it is land and 140 square miles (363 km2) of it (24.21%) is water.
