Flood Warnings and Advisories

High Streamflow Advisory – Cariboo

ISSUED: 11:00 AM November 2, 2020

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

  • Cariboo region including tributary rivers around Williams Lake, 100 Mile House, Quesnel and surrounding areas

A heavy precipitation event last week impacted the region and is leading to a prolonged period of unseasonable flows.
Current conditions include:

  • San Jose River above Borland Creek (Water Survey of Canada gauge 08MC040) has risen approximately 10 cm since Sunday, and is currently flowing at an estimated flow of 15 m3/s (between a 10-year and 20-year flow)
  • Baker Creek at Quesnel (08KE016) is flowing at 38 m3/s (2-year flow) and has eased slightly from a peak of 47 m3/s on Sunday

For most rivers in the region, flows are well outside the observed historic range of conditions for this time of year. Flows may remain high through the week, and while generally flows are expected to recede, there is the potential for additional rises in some rivers.

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 conditions and provides updates as conditions warrant.
