The Village of Cache Creek, B.C. ordered the evacuation of about a dozen properties Sunday evening, amid concerns the Bonaparte River could break its banks.
The order followed an evacuation alert issued Saturday night affecting about 300 people.
The B.C. River Forecast Centre issued a flood warning Saturday night, stating that the river was rising rapidly, with water moving at a 20-year flow rate.
Melting snowpack combined with unseasonable rain last week are driving the rising water levels.
The village said Sunday that it was clearing the dozen low-lying properties along the river as a precaution, to avoid the need to evacuate the properties at night should conditions worsen.
About 160 properties remain under an evacuation alert.
Residents are also being advised to stay well back from the river banks.
“The river initially rose rapidly from the heavy rain on Wednesday and Thursday, reaching an initial peak of 59 m3/s on Thursday evening,” stated the River Forecast Centre.
“The river began to recede on Friday, but as of Saturday morning has risen rapidly, likely due to the delayed response of flows in the headwaters. Nearby watersheds reached extremely high flows.”
The river last peaked on May 22, and the centre said it could meet or exceed those water levels Sunday.
Flood risk remains a concern throughout much of central British Columbia.

Flood watches are in place for the entire Peace and northeast regions and the Middle Fraser River from Prince George to Boston Bar.
