December 2 Starts Webinar Series on New USGS Nutrient Management Tool

On Friday, December 2, 2011 from 2:00pm to 3:00 pm (eastern), the USGS will conduct the first in a series of webinars on its six newly-developed regional SPARROW models and online decision support tool.  This first webinar will provide an overview of how the tool can be used to:  prioritize areas for nutrient reduction actions; identify which sources contribute the largest amounts of nutrients to downstream waters; and evaluate combinations of nutrient reduction scenarios.
