The growing snowpack in much of BC has created new concerns about flooding this spring.
Dave Campbell from the River Forecast Centre says its increased significantly since last month, to a provincial average of 168% of normal, up from 127% in April.
“If you look at the Okanagan, the snow basin index for May 1st is 206% of normal. That’s the highest recorded snow basin index we’ve got. We’ve been recording these since 1980,” Campbell told a teleconference.
The levels range from a high of 264% of normal in Upper Fraser West, to a low of 69% in Stikine.
Shaun Reimer from the province’s Public Safety and Protection Department, says it means an extra 225 centimetres of water on Okanagan Lake to deal with before the end of July.
“As of now, based on today’s forecast, we would expect to go over our full pool elevation somewhere in the line of 12 to 20 centimetres. Certainly that’s a far cry from where we were last year when we went 76 cm’s over.”
Reimer told the media, Okanagan Lake is rising about 5 cm’s a day, and is 72 cm’s from reaching full pool.
The experts say rain forecast for the middle of this week — combined with the snow melt — could make for a challenging week in the Interior.
