On December 10, 2025, the BC River Forecast Centre upgraded to a Flood Warning for our region. This includes the Sumas River and Lower Fraser tributaries. To read the full alert from the River Forecast Centre: https://bcrfc.env.gov.bc.ca/warnings/advisories/FWN_2025_12_10_1000_SC_upg.pdf.   

City staff are following Phase 2 - Rising Water of our Flood Response Plan for the Vedder River, which includes hourly dike patrols and the closure of all trails and parking lots along the Vedder River. We are asking people to stay away from these areas for now.  

River conditions are elevated from rainfall earlier this week and are now rising further in response to the series of atmospheric rivers that have been impacting the United States Pacific Northwest and the south and central coasts of BC through this week. The most recent storm started overnight Tuesday/Wednesday and is expected to continue through the day on Wednesday, indicating total precipitation amounts today of 80 to 110 mm in the Lower Mainland. 

Heavy rain and high streamflow bring increased risk for swift water hazards, flooding and landslides. Stay away from rivers, creeks and culverts and never drive through flooded roadways. 

Review personal flood emergency plans and be prepared to implement if needed.
