Weekend rainfall has led to high streamflow throughout the region over the past 2 days. Most areas have now experienced the peak river levels from this rainfall runoff. In small and mid-sized watersheds, river levels are expected to continue to improve through this week.
On the Bonaparte River, additional rises in river levels are possible over the coming few days as rainfall runoff works its way down from the headwaters; approximately 20-25mm of precipitation was observed over the weekend within the watershed.
In the South Thompson (and tributaries including the Shuwsap River) and North Thompson Rivers, rises in river levels in the 2-year to 5-year range are expected early this week, with the potential for flows on the South Thompson to reach up to 10-year flows later in the week. River levels on the Thompson River at Kamloops are forecast to reach around the 2-year level later this week.
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.
