Because the cooler Gulf waters do not mix well with the lighter and warmer fresh waters from the Mississippi River, oxygen is not replenished, resulting in a large Dead Zone in bottom waters. Inconsistent implementation of the Clean Water Act impacts any efforts to improve the health of the Mississippi River.
What happens to the Mississippi river when it flows into the Gulf of Mexico?
