Fraser River Freshet Advisory

May 16, 2018

The Fraser River freshet is an annual occurrence of high river flows due to spring thaw of snow and ice. The intensity is dependent upon the size of the snowpack and temperature, specifically sustained warmer than normal temperature.

A spike of hot weather combined with a spring storm can accelerate runoff from the mountains and lead to possible flooding along the Fraser River.

This page will provide continuous updates on the Fraser River streamflow and its possible impact in Delta.

Flows are expected to remain elevated through this week, but no flooding is expected for Delta. The Emergency Operations Centre will remain open.

Staff are monitoring the weather and river conditions and will continue with regular dike inspections.

Although there is no imminent flooding threat in Delta, the Emergency Operations Centre has been set up and is open to address any escalation of flood risk. 

Staff are continuously monitoring the weather and river conditions, and crews are inspecting dikes on a regular basis.

The Province has issued a High Streamflow Advisory for the Fraser River due to the persistent warmer than normal temperatures across British Columbia which have led to a much earlier than normal runoff period. Many of the gauge locations along the Fraser River are at or above their historic flows for this early in the freshet season.

Currently, Delta is not affected and there is no localized flooding. Boaters are advised to use caution when travelling on the Fraser River due to the higher water velocities and additional debris in the river.

Dike inspections have taken place, Delta staff are monitoring the river conditions and will update this advisory as conditions warrant.
