Map 3.3.2 Land use and water yield for the Fraser–Lower Mainland drainage region

Description for Map 3.3.2

The title of this map is “Land use and water yield for the Fraser–Lower Mainland drainage region.” It includes three components: a map on land use and two charts on water yield.

The map has two main components—a large map that shows land use for the drainage region and an inset that locates the region within Canada. The drainage region extends throughout much of the interior of the province between Vancouver and Prince George.

On the map dark red represents built-up, dark green represents natural and semi-natural, yellow represents agricultural land use and pale blue represents water. In 2011, the majority of the region’s total area was natural and semi-natural, followed by agricultural land use along the major river valleys. Most built-up area occurred in the Lower Mainland.

Provincial boundaries are indicated with a dashed grey line, while international boundaries are indicated by a thick grey line and thin dashed black line. Drainage regions are indicated by a black line. The locations and names of some of the larger population centres within the drainage region are included on the map. Land areas outside the drainage region are coloured medium grey while areas outside Canada are light grey. Major water bodies, like oceans and bays, are named.

Below the map, two charts provide information on water yield for the drainage region. The titles of the charts are “Monthly water yield, 1971 to 2013” and “Trends in water yield, 1971 to 2013.”

A line representing the smoothed trend of the raw annual data points is also included on the chart for Trends in water yield, 1971 to 2013.

Notes: The land use map is derived from remote sensing data products and administrative data sources. Water yield data were derived from discharge values contained in Environment and Climate Change Canada’s HYDAT database. Additional information is available in Appendix E.
