Flood Risk in Upper Fraser Basin Increases
Prince George, B.C.- The seasonal flood risk in the Upper Fraser basin is now considered “high” according to the latest snowpack report.
April was a very wet month, with well above normal precipitation in much of the province. The river forecast centre says the “combination of cooler and unsettled weather at the end of April has led to a delay in the onset of the snow melt season and increased snow water equivalents in many regions”.
According to the River Forecast Centre, snow basins increased in most areas of the province last month because of that cool wet weather. The Upper Fraser was 142% of normal for this time of year. The snow basin is below normal in the Nechako basin (81%).
According to the River Forecast Centre’s outlook , seasonal flood risk is high in the Upper Fraser, East Kootenay, Similkameen and Liard basins and moderately elevated in the South Thompson, West Kootenay and Okanagan-Kettle basins.
Of course, all that could change depending on the weather. Long periods of hot weather, or long periods of rain can bring on flooding in areas where the snowpack is below normal levels.
