Flood Warnings and Advisories
High Streamflow Advisory – Fraser River
UPDATED: 1630h May 15th, 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
Persistent warmer than normal temperatures across British Columbia for the past three weeks has led to a much earlier than normal runoff period for the Fraser River. High temperatures over the weekend and early this week are leading to rises in the headwaters of the Fraser River upstream of Prince George, and in other tributaries. Flows have been rising throughout the downstream reaches of the Fraser River. Note areas upstream on the Fraser River, including Prince George and Quesnel, are covered on a separate Flood Watch.
The Water Survey of Canada gauge Fraser River at Hope (08MF005) is currently flowing at 10,000 m3/s and rising. Water level at the Fraser River at Mission gauge (08MH024) today was 5.55m.
Flows are expected to continue to rise through the week, with increased rates in rise anticipated over the long weekend. Current flow forecasts for Hope are for flows to reach the 12,000 m3/s range this weekend and into next week. Water level forecasts predict water levels at Mission of 6.0 m on May 17th, 6.4m on May 19th, and up to 6.64m on May 24th. With on-going hot weather forecast through this weekend, and the potential for rain in the watershed next week, additional rises on the Fraser River are expected next week.

The River Forecast Centre will continue to monitor conditions and update this advisory as conditions warrant.
