The Mississippi River is perhaps the
most important river in the United States. It represents
the third largest drainage basin in the world. The basin
drains an area of 1,245,000 square miles, including
all or part of 31 states and two Canadian provinces.
The Mississippi River is vital to mid-continent transportation
and supplies water for drinking, irrigation, and industries.
Major floods on the Mississippi River have caused billions
of dollars in property damage.
