Ten years after creation landfall, scars from Hurricane Katrina still linger. And not only in a blighted houses that blotch some neighborhoods. The marshes and swamps that aegis New Orleans from a Gulf of Mexico still uncover justification of Katrine’s wrath.
The wetlands surrounding Delacroix, a fishing city to a southeast of New Orleans, were some of a hardest strike by a hurricane. Pounding surf, pushing winds, and a manly charge swell remade a marshes by picking detached mats of passed grass, stirring adult and disbursing soothing underlying sediments, scouring several new channels, and depositing leftover lees and waste in new areas.
Katrina delivered a vast swell of H2O that dramatically lengthened lakes, including Lake Lery and Petit Lake. It also scoured new channels and widened canals in ways that separated vast amounts of marshland. As seen in a 2015 image, flood-damaged foliage has returned to a normal color, though a lengthened waterways have persisted.
