Register Today for New Webinar Series on USGS Nutrient Management Tool!


On Friday, December 2, 2011, from 2:00-3:00pm EST, the United States Geological Survey will kickoff a host of webinars about its new regional SPARROW models and online decision support tool. The first webinar will provide an overview of the tool’s main uses: prioritizing areas for nutrient reduction, identifying sources that contribute large quantities of nutrients to local waterways, and evaluating nutrient reduction scenarios.

SPARROW relates in-stream water-quality measurements to spatial characteristics of watersheds. The tool uses these measurements to estimate the origin and fate of contaminants in river networks across the nation.

USGS plans to host five additional webinars between November 30 and December 8 that explain how the regional models can be used in specific areas of the country.
