A water quality improvement project has been initiated by several state and federal agencies via pollution prevention activities in the Sny Magill Creek watershed in northeast Iowa. The U.S. Fish and Wildlife Service, U.S. Geological Survey, U.S. National Park Service, the University of Iowa Hygienic Laboratory, and Iowa Department of Natural Resources (Iowa DNR) are cooperating to conduct a comprehensive, long-term water quality monitoring program designed to identify and document project benefits. The Iowa DNR-Fisheries Bureau's primary role is to monitor and assess responses in the fisheries population in Sny Magill Creek. Fish population sampling conducted in 1991 will serve as the pre-project baseline data set for future annual fisheries surveys. The initial fish population samples from Sny Magill contained species typically found in Iowa coldwater streams. The population was made up of eight fish species and was dominated by fantail darters, blacknose dace, redbelly dace, and johnny darters.
