Abstract |
The National Eutrophication Survey (NES) national maps of non-point source nitrogen and phosphorus concentrations in streams were evaluated for applicability and reliability. Interpretations on these maps which were based on data from 928 sampling sites associated with non-point source watersheds and the relationships of these data to general land use, and other macro-watershed characteristics, were compared with a nationwide set of non-point source stream nutrient data collected largely by the U.S. Geological Survey (USGS). In most areas where comparisons could be made the mapped interpretations agreed relatively well with USGS data. Revised reliability map insets based on these analyses are provided for maps of total nitrogen and total phosphorus concentrations. |
