National Water-Quality Assessment (NAWQA) Program
Agricultural Chemical Transport Study
Stream discharge and stream water quality
Stream discharge and selected water-quality constituents are monitored
at a near real-time basis at two sites in the South Fork Iowa River
Watershed to allow for better understanding of the relation between
stream discharge and stream quality. Data collected from site SF305
(South Fork near Blairsburg, Ia) will provide data from the headwaters
of the stream. Data collected from a site SF450 (Iowa River northwest of
New Providence, Ia) will help document effects of runoff from a larger
watershed and assist in the understanding of the transport
and behavior of natural and agricultural chemicals through the
watershed.
