The River Forecast Centre has issued a flood warning for the Nazko River and its tributaries.
Hot temperatures in the Nazko River basin and adjacent areas last week and Saturday have incurred significant amounts of snowmelt that resulted in bank full water levels in the Nazko River, which are threatening the local communities according to a report to EMBC.
The Nazko River is an un-gauged river system. It is estimated that the Nazko River above Michelle Creek, which is an inactive Water Survey of Canada station, is currently running at 65 m3/s, which is a flow between the two- and five-year return periods. The current hydrologic modelling indicates the streamflow in the Nazko River is expected to continue to rise rapidly this weekend into next week, peaking at about 130 m3/s, which is a flow about the 10-year return period, late Sunday or early Monday.
The current hydrologic modeling also indicates that the West Rod River near Cinema is rising significantly in the coming two days and expected to peak at 345 m3/s, which is a 10-year return period flow, on next Monday.
Please refer to the page of forecast for details of the above forecasts.
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 provides updates as conditions warrant.
