Concentrations, loads, and yields of nutrients (total nitrogen and total phosphorus) were calculated by the USGS for the Barnegat Bay-Little Egg Harbor (BB-LEH) watershed for 19892011 at annual and seasonal (growing and nongrowing) time scales. Concentrations, loads, and yields were calculated at three spatial scales: for each of the 81 subbasins specified by 14-digit hydrologic unit codes (HUC-14s); for each of the three BB-LEH watershed segments, which coincide with segmentation of the BB-LEH estuary; and for the entire BB-LEH watershed. Base-flow and runoff values were calculated separately and were combined to provide total values.
