Iowa WQIS integrates data gathered by IIHR—Hydroscience & Engineering (IIHR) and United States Geological Survey (USGS) and offers access to real time nutrient data with a range of water-related information such as precipitation, stream flow, and soil moisture. Our goal is to help researchers, agencies, and land-owners directly monitor the impact of land-use strategies/changes on downstream water-quality, enable watershed stakeholders to understand the fate and transport of nutrients in Iowa’s waterways; and help the state monitor the success of its Iowa Nutrient Reduction Strategy.
