Methods of data collection and results of analyses are presented for Lagrangian
and synoptic water-quality data collected from two agricultural drainages, the
Iroquois River in northwestern Indiana and Sugar Creek in northwestern
Indiana and northeastern Illinois. During six separate sampling trips, in
April, June and September 1999, May 2000, September 2001 and April 2002, 152
discrete water samples were collected to characterize the water chemistry over
the course of 2 to 4 days on each of these drainages. Data were collected for
nutrients, major inorganic constituents, dissolved organic carbon, trace
elements, dissolved gases, total bacterial cell counts, chlorophyll-a
concentrations, and suspended sediment concentrations. In addition, field
measurements of streamflow, pH, specific conductance, water temperature, and
dissolved oxygen concentration were made during all trips except April 1999.
