After Hurricane Ida made landfall on August 29, 2021, near Port Fourchon, La., the storm slowly churned inland over the coastal communities and marshes of Southeast Louisiana, eventually crossing the Gulf Intracoastal Waterway (GIWW) and, later, the Mississippi River. As Ida moved inland, the storm s counter- clockwise rotation dislodged an enormous amount of silt and vegetation from the marsh south of the GIWW and deposited it in the canal and in Lake Salvador to the north. The result: the GIWW was rendered impassable for commercial traffic between Miles 18 and 33 (west of Harvey Lock). Immediately after the storm passed, representatives from the New Orleans Engineer District, led by Vic Landry, operations manager of the GIWW, deployed to assess impacts to the waterway and craft a strategy for reconstituting the waterway. |
