Cold spring weather over the past month has transition to climbing temperatures over the past several days throughout the BC Interior. Daily maximum temperatures over the past few days has been in the in 10-18˚C range in Williams Lake and Prince George, compared to the sub-zero daily maximum temperatures that persisted earlier in the month.
Snowmelt rates have increased, with reports that the rapid transition in temperatures may be playing a factor in increased overland flow due to frozen ground conditions and ice-jamming.
River levels have been rising rapidly, with high flows being observed in small tributary rivers and creeks throughout the Interior Plateau from Cache Creek north through Williams Lake, Quesnel and west across the Chilcotin.
Current reported river conditions as of 8:00AM include:
- West Road River near Cinema (Water Survey of Canada gauge 08KG001) is flowing at an estimated 500 m3/s (20-year flow) and rising
- Baker Creek at Quesnel (08KE016) is flowing at 65 m3/s (approaching 5-year flow) and rising
- San Jose above Boreland Creek (08MC040) is flowing at 10 m3/s (5-year to 10-year flow) and rising
- Bonaparte River below Cache Creek (08LF002) is flowing at 35 m3/s (2-year to 5-year flow) and rising
Temperatures are expected to continue to rise, with today expected to be the hottest day of this current warm spell. Daytime high temperatures up to 16-19˚C are forecasted for Prince George and Williams Lake today, and then temperatures are expected to ease slightly into the rest of the week. Snowmelt rates are expected to continue to increase today, with continued rises in streamflow today and into Tuesday as a result of increased runoff.
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.
