High Streamflow Advisory – Fraser River
ISSUED: June 13, 2017 10:30 AM

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

  • Fraser River including areas of the main stem river from the Fraser Canyon downstream to the ocean

Flows on the lower Fraser River have been rising over the past two days in response to heavy rainfall in the headwaters last weekend. Flows are expected continue to rise through Tuesday with peak flows at the Fraser at Hope (Water Survey of Canada 08MF005) late-Tuesday evening of approximately 9,400 m3/s, and peak levels at Mission (08MH024) on Wednesday of approximately 5.3-5.4 m. Once rivers reach peak levels, flows are expected to recede through the remainder of the week.
The River Forecast Centre will continue to monitor river levels and will update the advisory as conditions warrant.

A High Streamflow Advisory means that river levels are rising or expected to rise rapidly, but that no major flooding is expected.  Minor flooding in low-lying areas is possible.
A Flood Watch means that river levels are rising and will approach or may exceed bankfull.  Flooding of areas adjacent to affected rivers may occur.
A Flood Warning means that river levels have exceeded bankfull or will exceed bankfull imminently, and that flooding of areas adjacent to the rivers affected will result.
