British Columbia’s Ministry of Land and Water says personnel are conducting assessments near a landslide that blocked the Chilcotin River in the province’s Interior, including to understand risks that might exist downstream.

A government statement says the landslide Wednesday blocked the river that feeds into the Fraser River, and a sudden release of water “may cause rapid rises in river levels downstream along the Fraser River” south to Hope, B.C.

The River Forecast Centre has issued a flood warning for the Chilcotin River upstream of the landslide and a flood watch downstream.
