The U.S. delegation, led by Sen. Mary L. Landrieu (5th L) and Dutch Crown Prince Willem-Alexander (6th L), stands on the Neeltje Jans waterworks barrier during an excursion to study flood-control systems in Hoek van Holland, the Netherlands, January 11, 2006. The Netherlands' ambassador to the U.S. invited Landrieu and a delegation including political, business and education leaders after Hurricane Katrina broke floodgates and levees, flooding most of New Orleans and all of neighboring St. Bernard and Plaquemines parishes.
