Data set |
Brief description |
Environmental samples |
Nutrient samples, including selected other data, collected
during water years 19922001 at NAWQA stream and river sampling
sites (19,098 Kilobytes) |
Load-model coefficients |
Regression coefficients and selected diagnostics for
models of nutrient loads at NAWQA sampling sites (468 Kilobytes) |
Daily streamflow |
Daily values of streamflow used to estimate nutrient
loads for selected water years at NAWQA sampling sites. Due to the
amount of data, streamflow files were separated into groups organized
by year in which the study unit began investigations and region of
the country. |
