1. GIS Aspect We used GIS to extract the watershed basin we were going to focus on so that we could obtain the NLCD landcover data for the catchments the development was going to be in.

2. Catchments of Interest

3. The Process • Clipped Haw River and New Hope watersheds from a file containing the entire water network for the Southeast U.S. • Overlaid NHD water body to locate Jordan Lake • Overlaid files for primary, secondary, and local roads to get an exact location • Overlaid catchment data • Added NHD flowline attributes data table • Overlaid NED file for the area to view the elevation of catchments

4. The Process • Joined catchment shapefile with NLCD flowline attributes to get CUMNLCD • Used identify function to select catchment of interest and obtain information about landcover • Compiled data to get total values

5. NLCD Classifications • 11 Open Water • 12 Perennial Ice/Snow • 21 Developed, Open Space • 22 Developed, Low Density • 23 Developed, Medium Density • 31 Bare Rock/Sand/Clay • 32 Quarries/Strip Mines/Gravel Pits • 33 Transitional • 41 Deciduous Forest • 42 Evergreen Forest • 43 Mixed Forest • 51 Shrub • 61 Orchards/Vineyards/Other • 71 Grassland/Herbaceous • 81 Pasture/Hay • 82 Row Crops • 83 Small Grains • 84 Fallow • 85 Urban/Recreational Grasses • 91 Woody Wetlands • 92 Emergent Herbaceous Wetlands

7. What’s In Store? How will the nutrient runoff rates be affected if we move the development farther upstream?
