Pacific Ocean watershed

Map of outline of Canada's Pacific Ocean watershed.

The Pacific Ocean watershed drains an area slightly greater than 1 million km2 that spreads from the border of the United States, in Alberta and British Columbia, to the Yukon, near the Mackenzie Delta. This watershed is separated by the continental drainage divide along the Rocky Mountains from north to south, dividing the streams that drain into the Pacific Ocean from those flowing into other oceans. The Fraser, Yukon and Columbia rivers are the largest rivers draining this region. The major cities are Vancouver, Victoria and Whitehorse.
