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-Atchafalaya River Basin

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 delivered to the Gulf of Mexico by the Mississippi-Atchafalaya River Basin.

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.
