Methods of data collection and results of analyses are presented for diel water-quality data collected from two nearby agricultural drainages in northwestern Indiana, the Iroquois River and Sugar Creek. During four separate sampling trips, in June and September 1999, May 2000 and September 2001, 208 discrete water samples were collected to document the aqueous chemistry over the course of 2 to 4 days on each of these drainages. Data were collected for nutrients, dissolved organic carbon, suspended sediment, major inorganic constituents (major cations and anions), trace elements, total bacterial counts, and chlorophyll-a concentrations. In addition, field measurements of water temperature, specific conductance, pH, and dissolved oxygen concentrations were made during all trips.
