CABLES The symbols for submarine and overhead cables do not differentiate between cables conducting electric power, often at high voltages, and other types of utility cables. Mariners are advised to exercise caution when passing under all overhead cables and to avoid anchoring or conducting seabed operations in the vicinity of submarine cables. The clearance of an overhead cable may differ from its charted value due to changes in atmospheric conditions, water levels and other factors. For additional information, consult Notice No. 16 in the Notices to Mariners, Annual Edition and the appropriate volume of CHS Sailing Directions.

AIDS TO NAVIGATION For additional information concerning aids to navigation, consult larger scale charts, the Pacific Coast List of Lights, Buoys and Fog Signals and Radio Aids to Marine Navigation (Pacific and Western Arctic).

VESSEL TRAFFIC SERVICES Traffic Services calling-in point with number; arrow indicates direction of vessel movement. For additional information concerning these services, see Radio Aids to Marine Navigation (Pacific and Western Arctic), Part 3.

MOORING BUOYS Private mooring buoys exist in this area, most established for recreational use.  Due to the number of buoys and frequency of change, individual buoys are not charted.  Many do not comply with Canadian Coast Guard standards and are difficult to see.

CAUTION Extremely hazardous eddies and turbulence may be encountered in Discovery Passage from the vicinity of Race Point to Plumper Point.  The flow close downstream of Ripple Rock may suddenly change from smooth to extremely turbulent.

See Notices to Mariners for subsequent corrections on this chart and Notices to Shipping in force for hazards or changes essential for the safety of navigation.
