Streamflow and water quality data collected by the US Geological Survey (USGS) and the Kentucky Natural Resources and Environmental Protection Cabinet from 37 sites in the Green River basin were compared to data from the USGS National Stream Quality Accounting Network (NASQAN) Station, Green River near Beech Grove, Kentucky. This comparison was used to determine variability of water quality data throughout the basin, and to determine if water quality data from the NASQAN station were representative of water quality data upstream. Water quality concentrations, yields, and trends were studied. Water quality data from the NASQAN station were fairly representative conditions throughout the basin for specific conductance, pH, phosphorus and nitrogen, but were not representative for chloride, sulfate, iron, and water temperature. Water quality characteristics which were not representative can generally be attributed to impacts of specific land uses such as coal mining or oil production. Mean concentrations of suspended sediment were similar, but extreme concentrations varied throughout the basin. There were no temporal trends detected in instantaneous streamflow, sulfate, or total iron concentrations. 33 refs., 17 figs., 18 tabs.
