Navigation Condition Surveys
The New Orleans District, Operations Division performs routine hydrographic surveys to monitor local river and waterway navigation conditions. This information is used as a decision making tool for channel maintenance operations.

The collected data is processed into MicroStation-format CADD files. The surveys are also very useful to supplement published navigational charts with more recent shoaling and other channel condition data.

This survey information is accurate as of the date of publication. Hydrographic survey data is subject to change rapidly due to several factors including but not limited to dredging activity and natural shoaling and scouring processes. The U. S. Army Corps of Engineers accepts no responsibility for changes in the hydrographical conditions which develop after the date of publication.

This data is intended for U. S. Army Corps of Engineers' internal use. This agency accepts no responsibility for errors or omissions contained in this data. The accuracy of this data is, therefore, not guaranteed. Prudent mariners should not rely solely upon it.
