AIDS TO NAVIGATION
Buoys marking a narrow or dredged channel are normally established on the edge
of the channel.  Light structures established to mark the main channel may be
located in shoal water some distance back of the channel edge.
INDEX

CABLES
For the mariners safety, all submarine and overhead cables are assumed to
conduct electric power at high voltages and contact with or proximity to these
cables poses an extreme danger.  Mariners are advised to exercise caution when
passing under all overhead cables.  However, if anchors become hooked onto a
cable, care must be taken not to sever the cable.  Cables installed since the
date of publication of this ENC may not be charted.  Sufficient clearance must be
allowed under all overhead cables.  Actual clearances may differ from charted
values due to changes in atmospheric conditions, ice buildup and/or water
levels and other factors.  For additional information, consult Notice to Mariners
No.  16 of each year and the appropriate volume of CHS Sailing Directions.

CAUTION
This chart was designed for offshore navigation.  For complete details of aids to
