For more than 100 years, the U.S. government has altered the channel of the Mississippi River to enable the passage of towboats and barges as far upstream as the Twin Cities.

First by constructing thousands of wingdams and then through a massive system of 29 locks and dams, the Corps of Engineers has created a consistent nine-foot-deep channel to ship crops and other goods from America's heartland to saltwater ports on the Gulf.

Though the system moves millions of tons each year (78.8 million tons in 2001), this expensive public works project blocked the river's natural hydrodynamic processes. The result: unintended costs-both environmental and economic.
