An assessment of areal and temporal variations in streamflow quality using selected data from the National Stream Quality Accounting Network
Timothy Doak Steele, Edward J. Gilroy, Richard O. Hawkinson
1974, Open-File Report 74-217
Streamflow chemical-quality data and stream-temperature data at 88 stations throughout the United States and Puerto Rico were analyzed to develop and to evaluate methodologies for the general assessment of the variation of the Nation's streamflow-quality conditions in space and over time. The spatial variation is described by the use of...
