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 tributaries. The USGS [...]
