LAFAYETTE, Louisiana – As Hurricane Ida struck Louisiana as a Category 4 hurricane on the anniversary of Hurricane Katrina, a major difference emerged between the two storms: the levee system , in large part, has withstood the test of the storm.
Governor John Bel Edwards said no major dykes failed during Hurricane Ida, thanks to a $ 15 million hurricane risk reduction system built in the aftermath of Hurricane Katrina in 2005. The system was only activated Sunday morning for the second time.
Floodwaters passed some dikes, while some failed on Sunday as the storm swept through the state.
Here’s what we know about the dike conditions so far.
