June 4, 2018 Update - The Fraser River at Mission is at 4.4m today, a significant decrease over the past 4 days.   

May 31, 2018 Update - The Fraser River at Mission is at 5.4m today and is expected to continue to decline over the next week.   The BC River Forecast Centre has ENDED the High Streamflow Advisory for the Fraser River from Lytton through Hope and the Fraser Valley.

May 28, 2018 Update - The Fraser River at Mission is at 5.8m today and is expected to slowly decline through the week. The River Forecast Centre is maintaining a High Streamflow Advisory for the Fraser River including the Fraser Valley: "Cooler temperatures are expected through this week across the BC Interior. Snow melt runoff is expected to decline through the week with the forecast weather patterns and dwindling snow packs. Flows are expected to slowly decline through the week, with forecasted flows of around 9,000 m3/s at Hope later this week. Water levels at Mission are expected to drop to the 5.4 m range by later this week."   

May 24, 2018 Update - The Fraser River at Mission is at 5.9m today and is expected to remain in the 5.8 to 6.0m range over the next several days.

May 22, 2018 Update - The Fraser River at Mission is at 5.9m today, a slight decrease over the past few days. The BC River Forecast Centre has issued a High Streamflow Advisory for the Fraser River today "Flows are expected to remain elevated through this week. With hot weather forecast over the headwater tributaries in the Upper Fraser and Thompson River basins, increased snowmelt runoff may lead to higher flows along the lower Fraser River into the coming weekend. Current modelling is indicating that flows should remain near current levels, however increases above current levels are possible."  

May 20, 2018 Update - The Fraser River at Mission is at 6.0 m today, a slight increase since Friday.  

May 18, 2018 Update - The Fraser River at Mission is at 5.9m today, a slight increase since yesterday.  The BC River Forecast Centre is predicting that levels could reach 6.6m on the Mission gauge by Monday, May 21. The 6.6m level is slightly above the level of 6.4m reached in 2012.    

May 17, 2018 Update - The Fraser River at Mission is at 5.8m today, a slight increase since yesterday.    

May 16, 2018 Update - The Fraser River at Mission is at 5.7m today, an increase of 0.2m since yesterday. The BC River Forecast Centre is predicting that levels could reach 6.7m on the Mission gauge by May 20.

May 15, 2018 Update - The Fraser River at Mission is at 5.5m today, an increase of 0.2m since yesterday.  The current BC River Forecast Centre is predicting that levels could reach 6.6m on the Mission gauge in the next 7-10 days (approximately May 22).   

The rising river levels will cause the local groundwater table to rise as well, so residents in parts of Fairfield Island may get some water in their basements as has occurred during past freshets.  It is recommended that precautions be taken, such as having a sump pump ready or moving items off the basement floor.

Press Release: Evacuation Orders Issued for Three Properties at Carey Point

May 14, 2018 Update - The Fraser River at Mission gauge is at 5.3m today, an increase of 0.4m since Friday. The current BC River Forecast Centre is predicting levels to reach 5.5m over the next few days. Current modelling indicates that water levels could reach 6 - 6.5 m on the Mission Gauge by May 22nd. As a comparison, the river reached 6.4m at Mission in 2012 and 7.1m in 1972.

May 11, 2018 Update - The Fraser River at Mission gauge is at 4.9m today, a slight increase from yesterday's 4.8m.

The BC River Forecast Centre has issued a streamflow advisory for the Fraser River. Warmer weather earlier this week has increased snowmelt runoff across the basin. Rises through the lower reaches of the Fraser River are expected to continue into the weekend (at Mission up to 5.5 m).  Over the weekend and into next week, high pressure is forecast to dominate the weather pattern across British Columbia, with warmer temperatures late-weekend, and hot temperatures forecast across the Interior early next week. Ongoing accelerated snowmelt is expected to lead to ongoing rapid rises on the Fraser River throughout next week. Current modelling is indicating the potential for flows at Mission of approximately 6.0 - 6.5 m by late next week.

As a comparison, the 2017 peak level was 5.6m, and the 2012 peak level was 6.4m. 

We will continue to monitor snowpack conditions and will provide updated seasonal flood risk forecasts as they become available from the BC River Forecast Centre.
