New Orleans-area officials prepare flood defenses as Tropical Storm Bertha approaches
New Orleans-area authorities prepared flood defenses as Tropical Storm Bertha moved along the northern Gulf Coast on July 21, closing most floodgates and lowering canal levels ahead of expected heavy rain.
The preparations involved coordination among the Sewerage and Water Board of New Orleans, levee authorities and officials across New Orleans metro parishes, according to a July 22 report by WWNO. The actions were part of a broader storm-preparation effort across coastal Louisiana and the metro area.
Flood-control operations ahead of rain
Officials closed most floodgates in the area as Bertha approached. The report does not say that every floodgate was closed, nor does it provide a precise total of gates involved.
Canal levels also were lowered in advance of the storm. That action was taken ahead of expected heavy rainfall, rather than in response to a documented post-storm flooding outcome.
The available report identifies Bertha’s movement along the northern Gulf Coast on July 21 and describes preparations reported July 22. It does not establish an exact rainfall forecast or total for New Orleans, and it does not document whether the storm ultimately caused major damage in the city.
Drainage response under scrutiny
The storm preparations came after criticism of the Sewerage and Water Board over failures during flooding that followed Tropical Storm Arthur in June, as well as additional flooding in July. Those recent events placed renewed attention on the performance of the city’s drainage and flood-protection operations.
Regional officials emphasized readiness across coastal Louisiana and New Orleans metro parishes as Bertha approached. The reported measures were official preparations intended to reduce risk from heavy rain; they were not a guarantee that flooding would be prevented.
Levee system background
The report also noted that the levee system has been reinforced since Hurricane Ida in 2021. That reinforcement is part of the region’s flood-protection context, while the immediate actions ahead of Bertha focused on floodgates, canal levels and coordination among local and regional agencies.
No post-storm assessment was included in the source material. As a result, the available information supports reporting on the preparations and the anticipated heavy-rain risk, but not conclusions about Bertha’s eventual impacts on New Orleans.
