The failure of the levees against Lake Pontchartrain and the Mississippi River caused the extensive flooding of New Orleans during Hurricane Katrina.
It was the failing of the levees against the Lake Pontchartrain and the Mississippi River that caused the extensive flooding of New Orleans during Hurricane Katrina. The levees were designed to protect the city from floodwaters, but they could not withstand the powerful surge of water from the hurricane. As a result, large areas of New Orleans were submerged, leading to widespread damage and loss of life.
