  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.

 As part of the larger USGS Hurricane Irene response effort, the Wisconsin Internet Mapping group (WiM) developed the Hurricane Irene Storm Surge Tracking Map to provide up-to-date information for emergency responders. During the storm event, the map linked to real-time streamflow and tidal data. Additional data, including storm surge, wave heights, and site photos, will be uploaded as post-storm conditions allow for data retrieval and processing.
