ISSUED: 3:15PM July 2, 2020

The River Forecast Centre is maintaining a Flood Warning for:

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

The River Forecast Centre is maintaining a Flood Watch for:

  • Peace Region (UPGRADED)
  • Northeast (UPGRADED)
  • Middle Fraser (UPGRADED) including tributaries including areas around Williams Lake and 100 Mile House
  • Chilcotin River and tributaries, including Big Creek, Chilko River

Significant rainfall has fallen over the past 48 hours across the BC Interior and North-east. Rainfall amounts over the past two days have been in the 30-80 mm range in the Peace and North-east, 25-35 mm in the Upper Fraser, 25-65 mm in the Cariboo Mountains and 30-50 mm in the Chilcotin.
Additional rainfall is expected through today and into Friday, with further unsettled weather in the long-term forecast. River levels are rising rapidly in headwater areas and are expected to see continued rapid rise through the day, with larger rivers rising into tomorrow or into the weekend.
Given the rainfall observed (and minor contribution of further rain forecast), significant rises in river levels are expected, with risks of flooding in many areas.

Most recent observations are:

  • Kiskatinaw River below Borden Creek (07FD019) is running at 50 m3/s (2-5 year flow)
  • Fraser River at Shelley (08KB001) is running at 2840 m3/s (1-2 year flow)
  • Bowron River below Box Canyon (08KD007) is running at 496 m3/s (5-10 year flow)
  • Quesnel River at Quesnel (08KH006) is running at 1020 m3/s (10 year flow)
  • Chilcotin River near Hanceville (08MB012) is running at 288 m3/s (2-5 year flow)

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.
