KAMLOOPS — The drought rating in the North and South Thompson River basin has been raised to Level 1 for the first time this year, following a spell of above normal temperatures that blanketed much of southern B.C.

While not unexpected, the warm weather has also increased the fire danger rating in the Kamloops area to ‘high’ with pockets considered ‘extreme.’

Elsewhere, the drought level on the Okanagan River basin has been increased to Level 2 Thursday (June 12), following three weeks at Level 1. The Similkameen and Nicola basins are also currently at Drought Level 2, and have been since May 29.

Meanwhile, the Chilcotin River basin was raised to Drought Level 2 Thursday (June 12), while the Clearwater, South Cariboo and Lower Thompson basin were all raised to Level 3.

“Drought conditions have intensified across much of the province following sustained hot and dry weather,” the River Forecast Centre said in a report, adding much of the province, including the Interior, had seen streamflow declines.

“Flows in some Okanagan, Lower Thompson and Vancouver Island tributaries have dropped to levels that can pose a risk to aquatic ecosystems.”

The River Forecast Centre also said with snowmelt runoff declining, further drought severity this year will depend on summer weather.
