Streamflow and Nutrient Flux of the Mississippi-Atchafalaya River Basin and Subbasins Through Water Year 2016

Graphics of Streamflow and Nutrient Flux for the Mississippi River near St. Francisville, Louisiana

The following graphics depict annual flux of dissolved nitrite plus nitrate (figure 1), total nitrogen (figure 2), total phosphorus (figure 3), dissolved orthophosphate (figure 4), and dissolved silica (figure 5), along with concurrent annual streamflow for the Mississippi River near St. Francisville, Louisiana (Station ID 07373420). Streamflow data are from Mississippi River at Tarbert Landing, Mississippi (U.S. Army Corps of Engineers [USACE] Station ID 01100Q).

The data used to generate the above graphs are available on the following page.

The U.S. Geological Survey defines a water year as October 1st of the previous year to September 30th of the designated year; for example, water year 2005 is from October 1st, 2004 to September 30th, 2005.
