South Bentinck Arm

Dean Channel is the upper end of one of the longest inlets of the British Columbia Coast, 105 km (65.2 mi) from its head at the mouth of the Kimsquit River. The Dean River, one of the main rivers of the Coast Mountains, enters Dean Channel about 9.5 km (5.9 mi) below the head of the inlet, at the community of Kimsquit.

Dean Channel was named by Captain Vancouver in 1793 after Rev. James King, Dean of Raphoe, Ireland. The channel was surveyed by Captain Richards in 1861 of the HMS Hecate. It is located within the Central Coast region.

Ending at the mouth of Cousins Inlet, which is the harbour for the abandoned town of Ocean Falls, the fjord's name changes to Fisher Channel down the west side of King Island. Below Fisher Channel's 40 km (24.9 mi) length the fjord merges with Burke Channel, which is a 70 km (43.5 mi) sidewater of the Dean/Fisher Channel on the east side of King Island, the name of the fjord changes to Fitz Hugh Sound, which is considerably wider than the upper part of the fjord at about 10 km (6.2 mi) in width and is itself about 60 km (37.3 mi) in length. Fitz Hugh Sound passes on the inside of Calvert Island and opens onto Queen Charlotte Sound just northwest of the opening of Queen Charlotte Strait.
