The James River monitoring station is located at Cartersville, Va., which receives about 60 percent of the streamflow from the 10,200 mi2 James River Basin. Of the nine tributaries monitored, this river contributes about 12 percent of the streamflow from the nontidal part of Chesapeake Bay Basin, making it the third largest streamflow source after the Susquehanna and the Potomac Rivers. The station is located upstream of municipal wastewater discharges of the Richmond, Va., area.
The James River contributes about 20 percent of the total phosphorus load and the second largest yield of total phosphorus from the nontidal part of the Chesapeake Bay Basin. In contrast, the James River contributes only about 5 percent of the total nitrogen load to the Bay. The relatively large phosphorus yield is caused by both point and nonpoint sources, including wastewater treatment plants, high concentrations bound to sediment in agricultural runoff, and naturally high concentrations in soils and rocks (Belval and Sprague, 1999).
