  1. SPARROW Watershed Modeling of the Entire Great Lakes Basin By Dale M. Robertson1, D.A. Saad1, G.A. Benoy2, W. Jenkinson3, and C.M. Johnston4 1 U.S. Geological Survey, Wis. WSC 2 International Joint Commission 3 National Research Council of Canada 4 U.S. Geological Survey, NH/VT WSC IAGLR Conference, McMaster University May 29, 2014 *dzrobert@usgs.gov (608) 821-3867

  2. Eutrophication Issues in the Great Lakes Lake Erie Manitowoc, Lake Michigan Cladophora on Beaches Pelee Island, Lake Erie

  3. The Importance of Nutrient Loading to Lakes is Well Known And several models available for smaller systems Delavan Lake, Wisconsin

  4. Goals of SPARROW Modeling for the Great Lakes Basin: 1. Determine P and N loading over the entire basin (largespatial scale). 2. Determine where are the main contributing basins (Rank all contributing basins based on loads and yields). 3. Determine what are the main causes of the high loads(Describe the relative importance of nutrient sources). 4. Provide information to various regional organizations to support regional interpretation and guide local, more in-depth studies.

  10. Major Criticisms of Past SPARROW Modeling • Only part (U.S. side) of the watersheds have • been modeled. 2. Spatial extent rather crude – ~HUC 11, ~100 km2 3. Interbasin transfers and direct deposition were not included
