Surrey Fish Facts

Surrey first developed a Watercourse Classification Map in 1995 that classifies streams based on their value as fish habitat for salmon and trout, collectively these are called 'salmonids'. This map is constantly updated when new information becomes available and is based on fish presence, duration and source of water, and surrounding vegetation potential. Watercourses are divided into 4 categories and colour coded like a traffic signal in RED, YELLOW and GREEN:

Class A (RED): Inhabited by salmonids year round or potentially inhabited year round.

Class A(O) (RED dashed): Inhabited by salmonids primarily during the over-wintering period or potentially inhabited during the over-wintering period with access enhancement.

Class B (YELLOW): Significant food/nutrient value. No fish present.

Class C (GREEN): Insignificant food/nutrient value. No fish present.

If you are interested in spotting salmon in Surrey there are great locations that have viewing spots perfect for seeing spawning salmon make their way upstream.

Why was a Fisheries Map created?

The Map was first developed to streamline the process for the City to conduct works in and around watercourses, and was used mainly by the Engineering Department and Operations crews. It is now also utilized extensively as a tool by land developers and planners to get an idea what the fisheries stream setbacks may be for new development areas.

The Watercourse Classification Map is compiled from various sources and is not warranted as to its accuracy by the City of Surrey. It is intended to be used as a planning tool only. New development applicants are advised to hire a Registered Professional Biologist to perform a watercourse assessment to verify the actual fisheries watercourses, with their related setback areas, on subject properties.
