Catfish Creek (Iowa)
From Wikipedia, the free encyclopedia
Catfish Creek is a minor tributary of the Upper Mississippi River. It rises west and southwest of Dubuque, Iowa. The Middle Fork flows under and then parallel to U.S. Route 20; the former Illinois Central Railroad, now the Chicago Central and Pacific Railroad has its mainline in it. The remaining forks of the creek are all south of Highway 52. Swiss Valley Park, maintained by Dubuque County, is in the main Fork. The section of the creek in Swiss Valley is a designated trout stream. In recent years, people have been trying to stop the erosion in this relatively flat way out of the Gorge of the Upper Mississippi. The North Fork of the creek has been proposed for a trail/park.
