The B.C. River Forecast Centre has ended the high streamflow advisory for the North Thompson River.

While the river is still high, it says flows in the river and its tributaries around Barriere, Clearwater and Blue River have dropped below a two-year return period.

A high streamflow advisory remains in effect for the South Thompson River – including Shuswap Lake – and the Thompson River from Kamloops to Spences Bridge.

The River Forecast Centre says flows on the South Thompson remain near a five-year return period, while the flow on the Thompson River downstream is between a two-to-five-year return period.

“Current weather models predict drier conditions for the upcoming week and water levels are expected to continue the downward trend,” the River Forecast Centre said Tuesday. “Since water levels are relatively high for this time of year, the river and lake systems are still vulnerable to any potential widespread heavy rainfall event in the upcoming weeks.”

“Smaller creek systems are highly vulnerable to short-duration and high intensity rain from convective thunderstorm activity.”

People are being told to stay clear of the fast-flowing rivers and potentially unstable riverbanks during the freshet season, which has been longer than usual due to a delayed seasonal snowmelt as well as significant precipitation through June and July.
