National Eutrophication Survey (NES) data for a nationwide collection of 928 non-point source watersheds were studied for relationships between macro-drainage area characteristics (particularly land use) and nutrient levels in streams. Both the total and inorganic forms of phosphorus and nitrogen concentrations and loads in streams were considered. For both nationwide and regional data sets, significant correlations were found between general land use and nutrient concentrations in streams. Mean concentrations were considerably higher in streams draining agricultural watersheds than in streams draining forested watersheds. The overall relationships and regionalities of the relationships and interrelationships with other characteristics are illustrated cartographically and statistically.
