The streams and rivers of the Iowan Surface partially form the foundation of our local ecosystems, everything from providing drinking water to producing floods. The Black Hawk Creek, Cedar River, and Maquoketa River were studied in the months of June and July of 2018. The goal of the research was to understand the ecology of each water way, how life was sustained by these rivers and creek and how the surrounding landscape may have determined the features of the waterways. Datasheets were filled out describing the sites’ ecological and geologic makeup, and GIS Trimble units were used to chart the points on a map. Wildlife observations were calculated for each river and creek. Black Hawk Creek wildlife was comprised of 35% mammals, 31% waterfowl, 23% amphibians, and 11% reptiles. The Cedar River had 64% waterfowl, 18% mammals, 9% reptiles and amphibians. Lastly, the Maquoketa River resulted in 30% mammals sightings and amphibians, 20% reptiles and waterfowl. Future work will determine how accurate the study was by testing different techniques and sampling times.
