Graphics of Streamflow and Nutrient Flux for the Lower Atchafalaya River at Melville, 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 Lower Atchafalaya River at Melville, Louisiana (Station ID 07381495).

• Annual MARB Nutrient Flux to the Gulf of Mexico for the Period of Record (through 2005)

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