The BC River Forecast Centre has issued a High Streamflow Advisory for the Fraser River which will remain in effect through the week and into the upcoming long weekend. A High Streamflow Advisory means that river levels are expected to rise rapidly, but that no major flooding is expected. Minor flooding in low-lying areas is possible.

Given the elevated water levels, the City of New Westminster is urging residents to remain aware and use caution when around the Fraser River shoreline, in particular, Quayside, Port Royal, Braid Industrial Area, Sapperton Landing and other exposed and low-lying areas adjacent to the Fraser or Brunette rivers. Please keep pets out of and away from fast-moving water.

Starting Friday, May 18, 2018, the wooden portion of the Quayside boardwalk will be closed for public use from Tenth Street (Westminster Savings Building) westward to the rail bridge due to high water levels. Please use the concrete pathway and use caution around the river.

Residents and visitors should remain aware when utilizing below ground parking areas adjacent to the Fraser River as they may experience minor flooding or seepage during high water levels. Residents and strata representatives are responsible for monitoring their parking areas, particularly those that contain electrical rooms, mechanical rooms, and equipment in case of flooding. Affected residents may wish to consider alternate parking arrangements for vehicles during this period.

The City of New Westminster will continue to monitor the situation by conducting regular dike patrols and liaising with provincial officials. The City will provide updates to the community as necessary via the City’s website and social media channels. 

Fraser River Freshet Preparation Plan

The City’s freshet monitoring and associated tasks have historically been referenced to the water level at the Environment Canada gauge at the Mission (08MH024) which is not influenced by tidal effects.  Tasks of the Freshet Preparation Plan are activated when the gauge readings reach the levels indicated in the following table:

Tasks / Historical References

Mission Gauge Water Level

CNW Starts Weekly Dike Patrols

6.0 m

CNW Starts Daily Dike Patrols

6.5 m

CNW Starts 24hr Continuous Patrol

7.0 m

Historical References

1948 Flood levels (June 8th)

7.56 m

1894 Flood Levels

7.92 m

Top of Dikes at Mission Gauge

8.53 m

 

The work plan also includes additional tasks to be completed during the freshet.  Regular updates will be provided as circumstances change.


A High Streamflow Advisory means that river levels are rising or expected to rise rapidly, but that no major flooding is expected.  Minor flooding in low-lying areas is possible.

A Flood Watch means that river levels are rising and will approach or may exceed bank full.  Flooding of areas adjacent to affected rivers may occur.

A Flood Warning means that river levels have exceeded bank full or will exceed bank full imminently and that flooding of areas adjacent to the rivers affected will result.
