Flood Warnings and Advisories

Northeast Region – High Streamflow Advisory (DOWNGRADED) – Cottonwood River, Quesnel River, Horsefly River, Bowron River (MAINTAINED)
High Streamflow Advisory (ENDED) – North Rockies, Upper Fraser, San Jose/Bridge
ISSUED: 11:30 AM June 8, 2020

The River Forecast Centre is downgrading to, or maintaining, a High Streamflow Advisory for:

  • Cottonwood River
  • Quesnel River
  • Horsefly River
  • Bowron River

The River Forecast Centre is ending the High Streamflow Advisory for:

  • North Rockies including the Muskwa River, Sikanni Chief River and tributaries west of Fort St. John and Fort Nelson
  • Upper Fraser River including Prince George and upstream and tributaries excluding the Bowron River
  • Cariboo including the San Jose River, Bridge Creek (excluding Cottonwood, Quesnel, Horsefly)

Rainfall from the weekend was focused in the Northern Rockies, with moderate rainfall amounts in the Robson Valley and Cariboo Mountains. Total weekend rainfall ranged from 20-65mm in the North Rockies, to <5 to 30 mm in the Upper Fraser and Cariboo Mountains.
River levels have peaked from this rainfall, with flows in the North Rockies reaching to around 2-year to 5-year flows in areas with the highest rainfall amounts.
High flows due to snowmelt and on-going wet weather persist in the Cariboo Mountains, including the Horsefly River, Quesnel River, Cottonwood River and Bowron River. Flows have peaked on these rivers, however river levels remain high and are in the 2-year to 10-year flow range. Flows are expected to continue to recede, however the rivers are sensitive to additional rainfall and may see additional rises over this week.

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.
