Watershed Management Authority


The Catfish Creek Watershed is a beautiful and diverse 57 square mile watershed that includes industrial centers, residential neighborhoods, rolling cropland, steep bluffs and rock outcrops, and dense forests. About half of the City of Dubuque lies in the watershed as well as parts of Asbury, Peosta and Centralia. Much of the watershed remains rural. The five forks of Catfish Creek support a diverse set of plants and animals and are a draw for hunters, fishers and those seeking to enjoy some of Dubuque County's most scenic areas, but they remain threatened by large amounts of soil and nutrients entering the water from both urban and agricultural runoff.
