'Douglas Channel' is one of the principal
inlets of the
British Columbia Coast. Its official length from the head of Kitimat Arm, where the aluminum smelter town of
Kitimat to Wright Sound, on the
Inside Passage ferry route, is 90 km (56 mi). The actual length of the fjord's waterway includes waters between there and the open waters of the
Hecate Strait outside the coastal archipelago, comprising another 60 km (37 mi) for 140 km (87 mi) in total.
A major side-inlet, the
Gardner Canal, is 90 km (56 mi) in length, and is accessed from the Kitimat Arm of Douglas Channel via Devastation Sound (20 km, 12 mi), which is on the east side of
Hawkesbury Island. South of Hawkesbury is Varney Passage (40 km, 25 mi), which has a sidechannel, Ursula Passage (30 km, 19 mi). Total waterway length of the
fjord dominated by Douglas Channel is therefore, not counting smaller side-inlets, is 320 km (200 mi), longer than
Norway's
Sognefjord (203 km, 126 mi) and rivalling
Greenland's
Scoresby Sund at 350 km (217 mi), though not as long as nearby Dean Channel's total of 335 km (208 mi).
Douglas Channel is a busy shipping artery because of the
aluminum smelter at
Kitimat, as
bauxite must be shipped in and smelted
aluminum shipped out. Recently-announced (2005) plans will see a major expansion of the port of
Kitimat as a container and bulk resources port, augmenting the port capacity of the British Columbia's North Coast currently a monopoly of the city of nearby
Prince Rupert.
The
Gardner Canal is important for being the location of the
Kemano generating station of the
Nechako Diversion, which was built to supply power for
Kitimat. The head of the Gardner Canal, also, is the mouth of the
Kitlope River, a major wildlife and wilderness preserve and area of outstanding natural beauty (and harsh weather).
The channel is named in honour of
Sir James Douglas, the first governor of the
Colony of British Columbia.
