  • Upper Fraser River, including tributaries like the McGregor River, Dore River and McKale River

A moderate rainfall event is occurring over the Upper Fraser and Cariboo regions. As of Thursday morning, rainfall totals over the past 24-hours range from 5 to 35mm – the highest occurring at Hedrick Lake (1A14P) automated snow weather station. Since rivers have remained high due to heavy rain over the past three weeks, some tributaries of the Fraser River are rising rapidly from this rainfall event. The Dore River near McBride is flowing at 109 m3/s (between a 2-year and 5-year flow) and rising. The McKale River near 940m Contour (08KA009) is at flowing at 73 m3/s (between a 2-year and 5-year flow) and rising. The Morkill River below Hellroaring Creek (08KA013) is flowing at 240 m3/s (between 1-year and 2-year flow) and rising. The McGregor River is flowing at 982 m3/s (between 1-year and 2-year) and rising rapidly. Increases are expected in the Fraser River over the upcoming days due to the rainfall.

The Quesnel River remains very high and is flowing at 985 m3/s (10-year flow) and may rise again over the following days due to the current rainfall.  The Fraser River near Marguerite is flowing at 4360 m3/s (between 1-year and 2-year flow). The San Jose River is flowing at 18.4 m3/s (between 20-year and 50-year flow).   

Fortunately, dry conditions are expected for the weekend.  The following week may continue the recent trend of unsettled summer weather.

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.
