Sixty-two watersheds and thirty lakes were sampled for one year. Nitrogen loads were estimated for each lake and watershed. The nitrogen loading rates varied from 8·0 to 38·5 kg/ha. A greater percentage of nitrogen was transported in baseflow than stormflow. Soil type and percentage of cropland had an influence on the nitrogen loading rate. Excessively well drained soils and higher nitrogen loading rates than poorly drained soils. Watersheds with a large percentage of the drainage area in cropland had the highest nitrogen loading rates. Broiler production did not have a large impact on the nitrogen loading rate.
