The San Jose above Borland Creek is flowing at approximately a 100-year flow at 30 m3/s with the rate of rise easing, according to the BC River Forecast.
The forecast centre is maintaining a flood warning Cariboo and Chilcotin (Fraser Plateau) including tributary rivers and streams around Williams Lake, Quesnel, Alexis Creek, Anahim Lake, Cache Creek and surrounding areas as well as the Nazko River and West Road River as of Wednesday morning, April 22.
The River Forecast Centre is also maintaining a flood watch for tributary rivers and streams around Chilako and south-west of Prince George.
“Temperatures through the region peaked on Monday and experienced a slight easing on Tuesday, with daytime highs in the 14C to 15C range around Williams Lake and Prince George, and up to 22C south around Ashcroft and Cache Creek. Overnight temperatures have risen to above freezing and as high as 10C overnight in Ashcroft. Weather over the next couple of days is expected to be more unsettled with showers,” stated the centre.
The River Forecast Centre stated the snowmelt rates have been elevated, with 10-25 mm of melt a day being observed at regional automated snow weather stations. The decrease in daytime high temperatures is being offset by the high overnight temperatures resulting in continued high snowmelt rates.
River levels have continued to rise, with some signs of reaching or approaching peak level in some areas, while other areas continue to see rises.
Current reported river conditions as of 6 a.m. Wednesday, April 22 include:
West Road River near Cinema (Water Survey of Canada gauge 08KG001) appears to have an easing in the rate of rise, with the potential for additional rises over the next two days depending on weather.
Baker Creek at Quesnel (08KE016) is flowing at approximately 110 m3/s (between a 10-year and 20-year flow) and rising
San Jose above Borland Creek (08MC040) is flowing at 30 m3/s (approximately a 100-year flow) with the rate of rise easing.
Bonaparte River below Cache Creek (08LF002) is flowing at 50 m3/s (five-year to 10-year flow) and rising.
“While there are early signs that river levels may be approaching or at peak levels, showers and on-going snowmelt over the next couple of days should keep river levels high and may lead to additional rises. Current modelling is indicating the potential for additional rises through the end of this week.”
The public is advised to stay clear of the fast-flowing rivers and potentially unstable riverbanks during the high-streamflow period.
