WESTERN RIVERS MARKING SYSTEM
The Western Rivers Marking System is a variation of the standard U.S. Aids to
Navigation System and is found on the Mississippi River and tributaries above
Baton Rouge, and on certain other rivers which flow toward the Gulf of Mexico.
- Red daybeacons, lights, and buoys mark the starboard banks and limits of
channels as vessels "return for sea" or proceed upstream.
- Green daybeacons, lights, and buoys mark the port banks and channels
while going upstream.
The Western River System varies of the standard U.S. system as follows:
- Buoys are not numbered.
- Passing daybeacons are not numbered but normally have an attached "Mile
Marker" board that indicates the distance in statute miles from a fixed
point (normally the river mouth).
- Lights on green buoys and on beacons with green daymarks show a single
flash, either green or white.
- Lights on red buoys and on beacons with red daymarks show a double flash
[Group Flashing (2)], which may be red or white.
- Isolated danger marks and safe watermarks are not used.
