UPDATE - High Streamflow Advisory – Fraser River
ISSUED: 13:30h May 28th, 2018

The River Forecast Centre is maintaining a High Streamflow Advisory for:

  • Fraser River  including the mainstem from Lytton through Hope and the Fraser Valley

Flows have remained elevated over the weekend as the snow melt runoff from headwater tributaries made its way to the lower Fraser River. Current flow at the Water Survey of Canada gauge Fraser at Hope (08MF005) is 10,200 m3/s, with water level at the Fraser River at Mission of approximately 5.8 m.
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.
Complete 10-day Lower Fraser River Water Level Forecasting and results are available at: http://bcrfc.env.gov.bc.ca/freshet/lower_fraser/LFR-10-DayFloodLevelForecasts.pdf
The River Forecast Centre will continue to monitor conditions and update this advisory as conditions warrant.
