River Navigation Conditions

 
New Orleans District Operations Division performs routine hydrographic surveys to determine waterway and river navigation conditions. These surveys are processed into CADD drawing files for review and analysis.

We use Bentley/Intergraph MicroStation Design File (DGN) file formats for this data processing. These survey files may be reviewed via your browser or downloaded for your use.
