Streams & Water Quality

Surrey stream.

Surrey has an open drainage policy, meaning that the City has endeavored to keep Surrey’s 1400 km of stream and creek habitats protected over the course of infrastructure development. Protecting Surrey's natural areas promotes healthy and productive stream environments and preserves the water quality for the aquatic species, such as salmon and trout, which live within the habitats.
