The City of Surrey implemented a Stormwater monitoring program in 1996. Since then, the City has collected stormwater flow and rainfall data and some limited water quality information at numerous sites throughout Surrey.
The purpose of the program was to collect data to be used to meet requirements of various programs in the City. Some of the more notable uses of the data include:
• to calibrate hydrologic models for selected catchments using reliable rainfall and flow data;
• establishment of baseline conditions and benchmarks for future comparisons;
• as background information for updating polices and design criteria and standards;
• to provide quick analysis of significant rainfall events and response to flooding events; and
• to be used in studies involving sanitary inflow and infiltration, stormwater, Low Impact Developments initiatives, fisheries, and water quality.
All data is collected and stored on FlowWorks, which is a web-based data server that provides data collection, reporting and flow analysis tools. The data from the monitoring program is analyzed and summarized annually.
The City of Surrey’s monitoring network is extensive and includes streamflow, water level and rainfall monitoring stations.
There are 11 streamflow monitoring stations:
• Serpentine River at 104 Ave.
• Morgan Creek at 160 St.
• Archibald Creek at 142 St.
• North Creek at Fraser Hwy.
• Bear Creek at King George Hwy.
• Quibble Creek at 88 Ave.
• Mahood Creek at 144 St.
• Latimer Creek at 88 Ave.
• Elgin Creek at 32 Ave.
• Campbell Creek at 12 Ave.
• Chantrell Creek at 32 Ave.
These stations record water level which is then used to calculate flow using a relationship between water level and flow measurements.
There are 23 water level monitoring stations:
• Manson Pump Station
• 192 Street (Fraser River)
• Upper Serpentine Pump Station
• Latimer Creek at Harvie Rd.
• Fry’s Corner North Pump Station
• Fry’s Corner Pump Station
