Flood map for New Orleans, Louisiana

New Orleans flood map and elevation view

Use this New Orleans, Louisiana flood map to inspect Lake Pontchartrain, the Mississippi River bend, and low-elevation neighborhoods across metro New Orleans. The page opens directly on New Orleans instead of making you pan from the national view.

What you can do

• Open a New Orleans-centered map instead of manually panning across the U.S.
• Compare elevation and flood scenarios around Lake Pontchartrain, the Mississippi River bend, and low-elevation neighborhoods across metro New Orleans.
• Start with a 3.0m flood setup, then adjust the slider for milder or more extreme water levels.
• Copy a permalink for the exact New Orleans scenario you want to share.

How to use it

1. Start with the default New Orleans map view and pan toward the shoreline, river, or neighborhood you care about.
2. Use flood mode for scenario testing, or switch to elevation mode to inspect terrain and relative height differences.
3. Click a specific point on the map for a location-based risk sample, then copy the permalink if you want the same view later.

Model notes

In and around New Orleans, levees, water bodies, and very flat terrain make relative elevation differences especially important. FloodMap USA is a screening tool for exploration and comparison, not a substitute for surveys, FEMA products, insurance decisions, or emergency instructions.
