Description of Work U.S. Geological Survey (USGS) scientists collect real-time, near-real-time, and synoptic flow and water-quality data (sediment and nutrients) from tributaries to the Great Lakes. The data provide baseline information to assess effectiveness of restoration and land management activities. Thirty of the 59 major downstream flow gages are continuously operating for water-quality samplings at these sites (number of sites reduced to 25 effective June 30, 2013). The work builds on current USGS monitoring efforts and those of partners in the Great Lakes. The results of this effort will provide information on nutrient and sediment loads and measure the effectiveness of restoration efforts in selected...

Description of Work The Great Lakes Observing System (GLOS) coordinates and integrates regional coastal observations supporting national and regional priorities including Great Lakes restoration. The Department of Interior backbone project is providing GLOS equipment for collecting water-quality sensor parameters and samples for organic and metal contaminants, and nutrient and sediment data in tributaries, embayments, and the nearshore to determine and guide restoration activities. Simulation models are also being developed that will provide quantifiable measures of restoration progress and comparisons of progress over time and space.
