PART 62_UNITED STATES AIDS TO NAVIGATION SYSTEM--Table of Contents

 

              Subpart B_The U.S. Aids to Navigation System

 

Sec. 62.51  Western Rivers Marking System.



    (a) A variation of the standard U.S. aids to navigation system 

described above is employed on the Mississippi River and tributaries 

above Baton Rouge, LA and on certain other rivers which flow toward the 

Gulf of Mexico.

    (b) The Western Rivers System varies from the standard U.S. system 

as follows:

    (1) Buoys are not numbered.

    (2) Numbers on beacons do not have odd/even lateral significance 

but, rather, indicate mileage from a fixed point (normally the river 

mouth).

    (3) Diamond-shaped non-lateral dayboards, checkered red-and-white or 

green-and-white, similar to those used in the U.S. Aids to Navigation 

System, as appropriate, are used as crossing dayboards where the river 

channel crosses from one bank to the other.

    (4) Lights on green buoys and on beacons with green daymarks show a 

single flash which may be green or white.

    (5) Lights on red buoys and on beacons with red daymarks show a 

double flash [Group Flashing (2)] which may be red or white.

    (6) Isolated danger marks are not used.
