Flows & Flow Monitoring
The city implemented a stormwater monitoring program in 1996, and since then has collected stormwater flow, rainfall data and some water quality information at numerous sites throughout Surrey.
This data is used in various City initiatives, including:
- Calibrating hydrologic models for selected catchments using reliable rainfall and flow data,
- Establishing baseline conditions and benchmarks for future comparisons,
- Giving background information for updating polices and design criteria and standards,
- Providing quick analysis of significant rainfall events and response to flooding events, and
- Facilitating studies involving sanitary inflow and infiltration, stormwater, Low Impact Developments initiatives, fisheries, and water quality.
This data is stored on FlowWorks, a web-based data server that provides data collection, reporting and flow analysis tools.

Streamflow monitoring stations
There are 11 streamflow monitoring stations that record the water level which is then used to calculate flow using the relationship between water level and flow velocity.
- Archibald Creek at 142 Street
- Bear Creek at King George Highway
- Campbell Creek at 12 Avenue
- Chantrell Creek at 32 Avenue
- Elgin Creek at 32 Avenue
- Latimer Creek at 192 Street
- Mahood-Bear Creek at 144 Street
- Morgan Creek at 160 Street
- North Creek at Fraser Highway
- Quibble Creek at 88 Avenue
- Serpentine River at 104 Avenue
Water level monitoring stations
There are 8 water level monitoring stations which record water level using radar or ultrasound, or a pressure transducer.
- Bear Creek at 152 Street
- 68 Avenue Ditch near 168 Street
- 168 Street Canal near 68 Avenue
- 192 South near 51B Avenue
- Latimer Creek at Harvie Road
- Nicomekl Sea Dam
- Serpentine River at 168 Street
- Serpentine River at Highway 10
The City of Surrey operates 11 tipping bucket rainfall gauges. Water collects into a cylinder, and into a seesaw-like container that tips after a pre-set amount of precipitation falls. Each tip is counted and summed. Only the 68 Avenue and 176 Street station is heated and therefore able to record snow water equivalent.
