Major Watersheds of Ozaukee County
A watershed is the land area from which surface runoff drains into a stream channel, lake, reservoir, or other body of water that flows toward a common outlet. For example, in this county, all the creeks and rivers eventually flow into Lake Michigan.
There are 7 WDNR designated watersheds
within the county. The largest watershed is the Milwaukee River South, which covers 164 square miles, or 66% of the county. The watersheds and sub watersheds in the county are shown below.
"A watershed is more than the physical landscape that is defined by its ridges with one outlet for water to flow. A watershed supports a variety of resources, uses, activities and values, where everything there is linked in such a way that eventually all things are affected by everything else in the watershed. Perhaps more importantly, a watershed contains the history of all who went before - and the spirit of those who touched it remains." - George Wingate, US Bureau of Land Management
