The Fraser River’s levels are heading up, and local emergency planners could be issuing the first heads-up warnings to those in the potential flood zone soon.

Heavy rains in the interior have swollen the Upper Fraser and there are flood warnings in Prince George.

Water levels near Langley are still relatively low, just above four metres at the Mission gauge.

If the level passes five metres, Langley Emergency Coordinator Ginger Sherlock and others will start issuing notifications to residents in the Fraser floodplain, near Fort Langley, Allard Crescent, and Glen Valley.

Water levels have hit as high as six metres in 2007, and again two years ago, without causing significant impacts. Water that high will flood some low-lying fields and campsites along the river.

“After six metres, we’re starting to look at roads being impacted,” Sherlock said.

Allard Crescent could be flooded out if water rises higher than that.

Much higher, and water will be on the dikes that protect much of the floodplain.

If that happens, emergency personnel will be monitoring the dikes 24 hours a day, watching for water seeping through or potential breaks.

Right now, no one knows what will happen, and whether water levels will hit dangerous highs, or simply peter out as in recent years.

It all depends on how much rain and heat hit the B.C. Interior in the next few weeks, and how fast the snow on the mountains melts.
