Clear Creek, a 270km² watershed located west of Coralville, IA, is heavily influenced by anthropogenic nutrient sources, exhibits erratic flows, and is very susceptible to extreme erosion of its banks during heavy rains. These rains contaminate the creek with excessive amounts of nutrients, sediment, and urban-related toxins, contributing to poor quality of downstream waterways. Water and its contaminants flow from the Iowa River to the Mississippi River and then discharge into the Gulf of Mexico. Our research utilizes water quality sensors to measure nitrate, oxygen, and phosphate at high sampling frequency. Data collected this from June 6^th-13^th, 2009 indicate that during a rain event the nitrate flux was as high as 0.519kg/min. Making the collected data accessible in real-time would provide the community with contaminant level information and awareness about the problem. Continuous monitoring of the watersheds and analyzing data obtained for various parameters provides a better understanding of Iowa's natural waters and hot the states' agricultural practice contribute to larger environmental problems. Also, it can allow for a plan to be developed in order to improve these issues in Clear Creek, the Mississippi, and even the Gulf of Mexico.
