WEF, along with the Notheast Midwest Institute, hosted a briefing this week on Capitol Hill to inform Congressional staffers and other interested parties on an updated web-based decision support system developed by the United States Geological Survey (USGS) National Water Quality Assessment (NAWQA) program.  The event, which took place on Friday, October 28, was moderated by WEF Government Affairs Vice-Chair, Alan Vicory, who is the executive director for the Ohio River Valley Sanitation Commission. 


The USGS presented updates of the SPAtially Referenced Regressions On Watershed attributes (SPARROW) watershed modeling tool with other presentations from by state officials from Minnesota and Tennessee on how their respective state programs utilize this tool.  The USGS described the ability of the SPARROW platform to provide online snapshots in time of nutrient loads, yields and sources for areas covered by the tool, which includes all areas of the contiguous 48-state with the exception of California and portions of the Southwest region. A real-time demonstration was also provided by USGS to illustrate the modeling and forecasting ability of the tool.  The online tool can be accessed at this link.
