Parts of British Columbia will likely enter 含羞草研究社渦nfamiliar territory含羞草研究社� with drought if they see another hot, dry summer, says the head of the province含羞草研究社檚 River Forecast Centre.

Dave Campbell says persistent drought conditions in B.C. stretch back to 2022, so the province is heading into this summer with 含羞草研究社渕ulti-year含羞草研究社� precipitation deficits.

Satellite photos show rivers across the province running narrower and shallower than the same time in 2023, which went on to be one of B.C.含羞草研究社檚 driest years on record.

With average snowpack levels lower than ever recorded in B.C. this past winter, Campbell says he含羞草研究社檚 expecting cumulative effects that could include water scarcity and other challenges.

含羞草研究社淲e know these antecedent conditions that we含羞草研究社檙e coming into this year are much more challenging than we started out last year with,含羞草研究社� he said in a recent interview.

含羞草研究社淭he concern obviously is if we get that hot, prolonged dry (period) that we含羞草研究社檝e seen last year and the year before as well. If that continues this summer, then really we are on a path toward things that we haven含羞草研究社檛 seen in recent memory.含羞草研究社�

Pockets of the Interior are especially dry. Campbell said he含羞草研究社檚 most worried about the effects of drought on smaller rivers and creeks in the central Interior.

含羞草研究社淧rince George, Quesnel, Williams Lake, Vanderhoof, that含羞草研究社檚 kind of the hot spot, and then the other (area) that would be a concern would be up in the northeast,含羞草研究社� he said.

The area around Vanderhoof, B.C., west of Prince George, has seen about 220 millimetres of rain over the past year when it typically sees about 460 millimetres, he said.

Images provided by the Canadian Space Agency appear to show the effects of persistent drought in the Interior when compared with those taken last spring.

An image taken last week by theEuropean Space Agency含羞草研究社檚 Sentinel-2 satellite shows the Quesnel River is narrower, with more of its banks exposed this month compared with an image taken a year ago. Last week含羞草研究社檚 photo shows patches of exposed riverbed and sandbars, indicating lower water levels in the tributary as it meets the upper Fraser River in Quesnel.

Satellite images tell a similar story in Fort St. James, B.C., where the water appears shallower this year as Stuart Lake feeds into Stuart River.

The Fort Nelson and Muskwa rivers also appear narrower, with more of their banks exposed compared with images taken in April 2023.

The Canadian Space Agency notes the images use infrared 含羞草研究社渇alse colour含羞草研究社� because it shows the boundaries between land and water more clearly than other renditions.

Campbell said parts of B.C.含羞草研究社檚 Okanagan will likely also see the effects of the moisture deficit and low amounts of snow that melted early this spring.

On northern Vancouver Island, meanwhile, he said the community of Port Hardy, B.C., has seen 1,260 millimetres of rain over the last year when it typically sees a little more than 1,800 millimetres.

It would take 含羞草研究社渁 few months of wet-season rainfall含羞草研究社� to ease the drought, he said.

B.C.含羞草研究社檚 snow survey last month found snowpack across the province was 含羞草研究社渆xtremely low,含羞草研究社� averaging 63 per cent of normal. The Quesnel area was listed at 52 per cent of normal, while the neighbouring West-Road Chilcotin region was at zero per cent.

Officials are expected to hold a press conference about drought and wildfires on Thursday as the province releases its latest snowpack bulletin.
