Streamflow and Nutrient Flux for Selected Mississippi River Subbasins with Varied Sizes, Hydrology, Land Use, and Geographic Location
Streamflow and Nutrient Flux of the Mississippi-Atchafalaya River Basin and Subbasins Through Water Year 2012
Streamflow and Nutrient Flux for Selected Mississippi River Subbasins with Varied Sizes, Hydrology, Land Use, and Geographic Location
The following list provides access to information on streamflow and nutrient flux for 22 subbasins within the
Mississippi-Atchafalaya River Basin (MARB) for the period of record through 2012. This information
extends the information provided by Aulenbach and others (2007) for the period of
record through water year 2005 and uses the same approach and methodologies. These subbasins vary significantly in
characteristics and are representative of other subbasins within the MARB. Data collection at the stations for a few of these
subbasins has been discontinued; however, information for the discontinued stations is provided by Aulenbach and others (2007)
where noted. Data from these stations and others are used in modeling
relations between watershed characteristics and nutrient yields and estimating nutrient yields in unmeasured subbasins,
for example the SPARROW Model (Alexander and others,
2000).

Graphs of the annual flux of dissolved nitrite plus nitrate, total nitrogen, total
phosphorus, dissolved orthophosphate, and dissolved silica, along with concurrent annual
streamflow are available for all of the above basins.
