Abstract

Upper Catfish Creek is located in a 9,300-acre watershed that flows through two significant natural resources, Swiss Valley Park and Swiss Valley Nature Preserves, one of the largest nature preserves in the Midwest. According to DNR’s 2002 305(d) report, that portion of the creek within the park and preserve is classified as a Class B(CW) cold water stream of which a portion has naturally reproducing trout (one of only 30 in the state of Iowa with this capability). Urban sprawl is a real threat to the Upper Catfish Creek Watershed. Currently, 10% of the watershed is residential, but 27% is zoned residential or commercial. The watershed is near Dubuque city limits but the jurisdiction is in the county. Differing criteria for land development between city and county jurisdictions further entices developers to build in outlying areas. County leaders agree there is more that needs to be done and will work with municipalities on uniformity of regulations and follow-up measures. We propose to set up key urban conservation practice models that will address storm water runoff and water quality which can be learned about and viewed by city and county officials, engineers, developers, etc. This would be part of a larger initiative including an educational campaign, inter-jurisdictional planning, the development of a land use GIS database, and agricultural conservation practices. The successes coming out of and learned about this watershed will serve as a model to spread county-wide.
