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.

Current velocities represent normal maximum rates at springs. 

See Canadian Tide and Current Tables Vol. 7 for current information.

MARINE FARMS Aquaculture facilities may be found in areas covered by this chart. Symbols for these facilities do not necessarily represent their exact location. Submerged debris may also remain in abandoned sites in areas not recently surveyed. Caution should be exercised while navigating in the vicinity of all aquaculture sites. For more information, consult Sailing Directions, Notices to Mariners and Notices to Shipping.

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.

SKIDEGATE CHANNEL

TIDAL RANGE The tidal range decreases significantly from east to west through Skidegate Channel.  Approximate levels above chart datum at selected locations within Skidegate Channel are shown below for various high waters at Village of Queen Charlotte.

Slack water at East Beacon occurs about 1 to 2 hours after high or low water at Village of Queen Charlotte.

Slack water at McLellan Point occurs about 3 to 3 hours after high or low water at Village of Queen Charlotte.

West-flowing currents at McLellan Point can attain velocities of 7 knots.
