 Throughout the country, declining water quality in rivers and streams has been linked to excessive inputs of nutrients, particularly nitrogen and phosphorus. The SPARROW nutrient modeling project recently released results for Major River Basin 3 (MRB3), which includes the Great Lakes and the Ohio, Upper Mississippi, and Souris-Red-Rainy River basins. Three journal articles were published in August detailing the data, model, and decision support system. In addition, two online mapping tools are also available: the MRB3 SPARROW Mapper provides load and yield data, source information, and displays rankings; and the SPARROW Decision Support System, which can be used to predict water-quality conditions, track nutrient transport downstream, and evaluate management source-reduction scenarios.
