Despite our best efforts to kill it, the Fox River just keeps on rolling along…

One of Kendall County’s most valuable natural assets is it’s surprisingly extensive system of waterways.

The Fox River is, of course, the most dominant waterway in the county. The river enters the county in northwestern Oswego Township and then cuts diagonally cross county, running along the border between Oswego and Bristol townships, similarly along the Bristol-Kendall Township line and then into Little Rock Township and through Fox Township before exiting the county and heading southwesterly into LaSalle County.

The other major system of waterways in the county is the Aux Sable watershed. In terms of area within the county’s bounds, the Aux Sable watershed is actually the county’s largest, since it drains all or parts of six of Kendall County’s nine townships.

That Kendall has two major drainage basins separated by what the voyageurs used to call a “height of land,” is a rarity for such a small county. Thanks to that accident of geography, more than half the county’s surface waters drain directly into the Illinois River via the large Aux Sable system while the rest of the county drains through the Fox River watershed.

The Fox River’s watershed includes most of the county’s largest creeks, including Big Rock and Little Rock creeks, Rob Roy Creek, Blackberry Creek, Waubonsie Creek, and Morgan Creek.


The county’s earliest residents, Stone Age Native American hunters and their families, found that the area’s numerous waterways made it a nice place to live. Those earliest inhabitants lived around the lakes, sloughs, and swamps left behind as the last glaciers retreated because game was abundant in those areas, as were many other necessities of life. Camp and village sites dating back thousands of years found overlooking the county’s waterways and wetlands show that those early residents depended on streams for clams and other invertebrates and fish, on swamps and sloughs for small and big game, and on rich bottomland for edible plants, from nuts and berries to wild grain, that could easily be gathered in abundance.

After European explorers arrived, the lifestyles of local Native Americans changed as they gathered materials to trade for brass pots, iron and steel axes, woolen blankets, linen cloth, brandy and run, firearms, and silver ornaments and glass beads. The area’s waterways proved even more valuable in that new mode of life, as local tribesmen trapped beaver, muskrat, fox, and other fur-bearing animals whose skins were sent back to Europe in trade for items that quickly became necessities.

In those days, the various branches of the Aux Sable (French for “Sandy Water”) were important geographical references, and were referred to as landmarks in several major treaties between the U.S. Government and the Indian tribes living in northern Illinois.

By the time the first permanent white settlers arrived along the banks of the Fox River in the 1820s, fur-bearing animals were nearly extinct and game in general was scarce due to over-hunting and over-trapping. In fact, the earliest Kendall County settlers found they had to import food to what had once been one of the richest natural areas on Earth.


According to this survey map, a sawmill was located at the mouth of Hollenback Creek in Fox Township in 1838, illustrating that even some of the smallest creeks in the Fox River’s watershed were harnessed to power mills.

Waterways proved just as important to the economics of early settlers as they had to Native Americans, although in far different ways. The settlers quickly harnessed the power of the county’s waterways through the construction of dams. The resulting water power was put to work turning mill wheels to grind corn and other grain and to saw the wood needed to build homes for the area’s fast-growing population. Virtually every substantial stream in the county—and even some insubstantial ones—boasted a mill of some kind at some time or another. And the Fox River itself eventually became dotted with dams along its length through Kendall County that provided water power for many more mills.

With the tribes gone (all Indians were removed from Northern Illinois in 1836), game slowly recovered, although the buffalo never returned to Illinois after it was wiped out about 1800 by a combination of over-hunting for skins and vicious winters.

Within a few generations, however, the newly recovered big and small game was again decimated by over-hunting. It has only recently began to recover relatively recently once again as fewer and fewer county residents hunt and trap during the winter months and as development has made hunting either inappropriate, unwelcome, or downright dangerous.


This group of youngsters was captured in a photograph around 1910 fishing in Waubonsie Creek near downtown Oswego. By then, the county’s two main watersheds was already badly polluted by homes, farms, and businesses.

Settlement also meant extreme changes in water quality for the county’s streams. Kendall County’s once-clear and cool streams were slowed by dams, choked by silt, and poisoned by fertilizer and other chemicals running off of cultivated fields. After the settlement era, the Fox River in particular became a dumping ground for growing industries upstream in Kane County and for human waste from virtually everywhere else in the river’s drainage basin. By the 1950s, the river and many of the county’s creeks had become little more than cesspools with currents.

But beginning in the 1970s, word on cleaning up the county’s streams began, thanks to federal clean water regulations, without which most of our streams would be open sewers still. Today, the Fox River is prized for its smallmouth bass fishery and the once-rare wildlife it attracts and nurtures. The City of Aurora even uses it for drinking water, and Oswego, Montgomery, and Yorkville are talking about doing that, too.

But Kendall County has yet, I think, to realize how valuable a resource the river and its tributaries is and how valuable it could be. The good news, I guess, is that at least we’ve at least temporarily quit trying to kill the river and its tributaries. The bad news is it took the federal government to make us do it.
