Soldiers and sailors from across France quickly mobilized and went to Paris where they joined forces with local police and firefighters. These first responders launched search and rescue missions throughout the flooded zone. The square in front of the Notre Dame cathedral became a launching point for boats into the still rising Seine.
The Seine flowed much faster than usual reaching speeds of approximately 25 miles per hour. Its color changed to a murky yellow and its became frothy. Parisians could watch the powerful eddies swirling on the water's surface.
