The Metro Vancouver watersheds, also known as the Greater Vancouver watersheds, supply potable water to approximately 2.4 million residents in the Lower Mainland of British Columbia. They provide tap water to a land area covering more than 2,600 km², including cities such as Vancouver, Langley and Richmond. From west to east, the watersheds are the Capilano (19,545 hectares), the Seymour (12,375 hectares), and the Coquitlam (20,461 hectares). They are located in the North Shore Mountains and Coquitlam Mountain, respectively. Each watershed possesses a reservoir for water storage purposes, under the control of Metro Vancouver. The reservoirs are supplied by about 3.5 metres of rain and 4.5 metres of snowpack annually. Two additional off-catchment areas (Lower Seymour Conservation Reserve and Or Creek watershed) under control of Metro Vancouver contribute to the water supply. The watersheds have a long history of controversies surrounding logging, highway development, and salmon run conservation.
