The River Forecast Centre is maintaining a high streamflow advisory for tributaries around Prince George and Mackenzie, including areas around Bear Lake, Aleza Lake, Giscome, the Cottonwood River, Chilako River, Salmon River, Willow River, Pack River and surrounding areas
A high streamflow advisory means that river levels are rising or expected to rise rapidly, but that no major flooding is expected. Minor flooding in low-lying areas is possible.
The River Forecast Centre is ending a high streamflow advisory for the Cariboo region including tributaries around Quesnel and Williams Lake, including the San Jose River.
Flows have remained high throughout the region due to on-going snowmelt and unsettled weather. Many rivers have seen some stabilization or declines in flows over the weekend; however, conditions remain high (two-year flows or higher).
In the Cariboo, flows have continued slow declines from peak levels experienced in late-April and early May. Flows are expected to remain high in the Cariboo, however significant rises above current levels (e.g. return to previous peak levels this season) are unlikely.
Rivers around Prince George remain high. The Water Survey of Canada gauge Pack River at outlet of Macleod Lake reached a peak of approximately 420 m3/s over the weekend (between a 20-year and 50-year flow). Flows in the region remain elevated, however are expected to see improving conditions through the week.
With elevated flows and limited channel capacity, rivers around Prince George and Mackenzie remain sensitive to additional rainfall. Additional rises in river levels are possible this week due to forecasted warming and the potential for increased snowmelt rates. 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 conditions and will provide updates as conditions warrant.
