Why Round River?     Aldo Leopold (1887-1948) was an Associate Director of the Forest
            Resources Laboratory at the University of Wisconsin.  He founded the
            science of Game Management and served as a consulting forester.  But
            he is probably best known as a naturalist and conservationist through his
            writings.  His major contribution, A Sand County Almanac,
            was
            published a year after his death.  One essay in this book was
          titled "The Round River".  Below is an except from this essay. 
            "One of the marvels of early
              Wisconsin was the Round River, a river that flowed into itself, and thus
              sped around and around in a never-ending circuit.  Paul Bunyan
              discovered it, and the Bunyan saga tells how he floated many a log down
              its restless waters."  
            Clay Hill's constructed wetland is a
              "round river".   Its headwaters are in the Joan White
              Howell Environmental Education Center and pavilion, its main stem is the
              wetland cells and its mouth is a 250 aquarium in the center.  Our
              "wastewater" is cleaned by plants and microorganisms that reside
              in the wetland cells. You can read more by following the links
