51% of the nitrogen flux into the Gulf of
Mexico comes from interior basins of the upper Mississippi watershed
above the Missouri and Ohio Rivers. However, this section supplies
only 22% of the total volume of River water entering
the Gulf. Since the mid 1980s, large hypoxic areas
have been documented in the near-shore waters off the Louisiana
and Texas coast. However, there
have been no documented hypoxic
or low oxygen conditions in the
mainstem ofthe Mississippi River.
