High Streamflow Advisory – Be Prepared for Heavy Rain, Rising Rivers and Potential Flooding

Maple Ridge, B.C., September 26, 2025 - The River Forecast Centre has issued a High Streamflow Advisory for the South Coast, including Metro Vancouver. This advisory means that river levels are expected to rise rapidly, but major flooding is not expected at this time. Fast-flowing rivers and streams still pose a risk to public safety, and minor flooding in low-lying areas is possible. 

Environment Canada is forecasting significant rainfall this weekend, with up to 100 mm possible in some areas, beginning Friday and continuing into early next week. While many rivers are currently at below-normal levels due to summer drought, residents are advised to take precautions as water levels in the Alouette and Kanaka Creek Rivers may rise quickly. 

City Preparedness 

To reduce flood risks and ensure public safety, the City has been taking proactive measures, including: 

  • Inspecting and clearing catch basins, culverts, and drainage intakes in priority areas 
  • Monitoring river and creek levels, including the North and South Alouette, Kanaka Creek, and Fraser Rivers 
  • Inspecting and maintaining dikes and pump stations 
  • Sharing flood preparedness information with the public 
  • Coordinating with key agencies and partners 

Stay Safe and Reduce the Risk of Flooding 

The City encourages residents to do their part to prepare and stay safe: 

  • Clear leaves and debris from gutters and catch basins near your home to help prevent localized flooding 
  • Avoid walking, cycling, or driving through flooded areas 
  • Stay away from rivers, creeks, and unstable banks 
  • Keep children close and pets on leash and safe round fast moving waters 
  • Check on neighbours who may need assistance 
  • Report downed trees, road debris, or blocked storm drains on City property to the City’s 24-hour line at 604-463-9581 or at MapleRidge.ca/Report 
  • Stay at least 10 metres away from any downed power lines and call BC Hydro at 1-800-BCHYDRO or *HYDRO (*49376) 

Be Prepared for Emergencies of All Kinds 

With the fall storm season underway, residents are advised to be prepared, stay alert, and take precautions to keep families and neighbourhoods safe.
