The diversion measures aimed to lessen the damage caused by an unusually severe spring flood season. The Advanced Hydrological Prediction Service (AHPS) of the U.S. National Weather Service reported that the Mississippi River at New Orleans reached 17.05 feet (5.20 meters) at 9:00 a.m. CDT on May 20, 2011. This was just above the flood stage fo...
