Flood Warnings and Advisories

 

Northeast Region – Flood Watch – Upper Fraser River (MAINTAINED), Quesnel River (MAINTAINED)
High Streamflow Advisory – Chilcotin (NEW)

ISSUED: 12:30PM June 26, 2020

The River Forecast Centre is maintaining a Flood Watch for:

  • Upper Fraser River including tributaries and the mainstem at Prince George and upstream
  • Quesnel River

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

  • Chilcotin River and tributaries, including Big Creek, Chilko River

Warm weather last week followed by moderate to heavy rainfall in some locations of the Upper Fraser River and Quesnel region created large flows.  Smaller systems like the Dore River and McKale River rose rapidly to 50-year flow levels on Tuesday.  The response on the larger system of the Fraser River is more delayed.  The Fraser River at McBride and Red Pass peaked on Thursday, whereas stations at Hansard, Shelley and South Fort George are expected to peak today (Friday) from this recent weather pattern.   The Quesnel River is gradually rising.

The Chilcotin River and other tributaries have been rising over the past week and are currently between 1-year and 2-year flows.

Current observations as of Friday, June 26 at 11:00 PST:

  • Dore River near McBride (08KA001) peaked on Tuesday at 170 m3/s (50-year flow).  Flows have receded and are flowing at 80 m3/s
  • McKale River near 940 m Contour (08KA009) peaked on Tuesday at approximately 140 m3/s (between a 50-year and 100-year flow).  Flows have receded and are flowing at 82 m3/s
  • Morkill River below Hellroaring Creek (08KA013) peaked late on Tuesday at approximately 460 m3/s (10-year flow).  Flows have receded and are flowing at 300 m3/s
  • Fraser River at Red Pass (08KA007) peaked on Thursday morning at approximately 360 m3/s (between a 20-year and 50-year flow).  Flows are slowly receding and are flowing at 327 m3/s
  • Fraser River at McBride (08KA005) peaked on Thursday at 1230 m3/s (between 20-year and 50-year flow).  Flows remain relatively high and are flowing at 1200 m3/s
  • Fraser River at Hansard (08KA004) are currently peaking at approximately 2670 m3/s (between 10-year and 20-year flow)
  • Fraser River at Shelley (08KB001) is currently peaking at 4000m3/s (between 5-year and 10-year flow)
  • Fraser River at South Fort George (08KE018) is at 9.3 m and leveling off
  • Quesnel River at Likely (08KH001) is flowing at 568 m3/s (20-year flow) and rising
  • Chilcotin River near Hanceville (08MB012) is flowing at 283 m3/s (2-year flow)
  • Chilko River near Redstone (08MA001) is flowing at approximately 260 m3/s (between 1-year and 2-year flow)
  • Taseko River at Outlet of Taseko Lakes (08MA003) is flowing at 158 m3/s (2-year flow)

Larger river systems in the Upper Fraser and Quesnel are approaching peaks from recent weather events.  Flows are remaining very high in the region and rivers are vulnerable to the possibility of more rainfall over the weekend.

The Chilcotin River and tributaries have been modestly rising over the past week to between 1-year and 2-year flows.  There is light precipitation in the forecast for the weekend (10-15    mm) and models currently forecast flows reaching up to 5-year return periods.  This is a different type of storm system than the one that affected the region in July 2019.  It is not expected to be a large region-wide flood event. However, if heavy localized rainfall occurs it could create localized flooding issues.

The public is advised to stay clear of the fast-flowing rivers and potentially unstable riverbanks during the high-streamflow period.

The River Forecast Centre continues to monitor the situation and provides updates as conditions warrant.

Levels of Warnings/Advisories:

  1. High Streamflow Advisory: River levels are rising or expected to rise rapidly, but that no major flooding is expected. Minor flooding in low-lying areas is possible. This is the lowest level.
  2. Flood Watch: River levels are rising and will approach or may exceed bankfull. Flooding of areas adjacent to affected rivers may occur. This is the intermediate level.
  3. Flood Warning: River levels have exceeded bankfull or will exceed bankfull imminently, and that flooding of areas adjacent to the rivers affected will result. This is the highest level.
