Why Okanagan snowpack levels might not be as high as early measurements suggest

A gauge malfunction measuring an important Okanagan watershed could have resulted in false high readings for the January snowpack.

Shaun Reimer of Ministry of Forests and Lands says the problem was noticed and corrected earlier this week.

“I had concerns about the high readings from the Mission Creek snow station, but they didn’t seem surprising, since we had that early October snow,” Reimer says.

Inspectors encountered a problem with the gauge, made repairs and recalibrated it on Tuesday. The readings for snow water equivalent – actual moisture in the snow – have since declined somewhat.

Reimer says readings are still above average at the station but not as high as they were prior to Tuesday. He says a clearer picture of Okanagan snowpack levels will be available next week when the monthly river forecast figures are released.

“We’ll see where it’s at. Mission Creek is one of our main gauges for Okanagan Lake,” he says.

February's River Forecast Data is generally the information that provides him with his 'marching orders' for controlling the spring freshet.

Reimer says to this point he’s taken a conservative approach to water levels on the lake this year, following three high water years out of the last four.

“I’m scheduling to be below monthly targets. We’ll be increasing outflows through the dam into the Okanagan River Channel in Penticton on Monday. We still have some fishery issues to work through, but flood control is first and foremost,” he says.

The River Forecast Centre’s most recent update says Okanagan snowpack levels were at 113 per cent of normal on Feb. 1, with the North Thompson at 109 per cent and the South Thompson at 103 per cent.

The Similkameen snowpack was measured at 106 per cent of normal.

A stormy first half of January was followed by a relatively dry and cool second half, which resulted in a provincial decrease in average snowpack readings from 122 per cent in December to 109 per cent as of Feb. 1.

The next River Forecast update is scheduled for release on Feb. 9.

I have been looking for news in the South Okanagan - SImilkameen for 20 years, having turned a part time lifelong interest into a full time profession. After five years publishing a local newsletter, several years working as a correspondent / stringer for several local newspapers and seven years as editor of a Similkameen weekly newspaper, I joined iNFOnews.ca in 2014. My goal in the news industry has always been to deliver accurate and interesting articles about local people and places. My interest in the profession is life long - from my earliest memories of grade school, I have enjoyed writing.
As an airborne geophysical surveyor I travelled extensively around the globe, conducting helicopter borne mineral surveys.
I also spent several years at an Okanagan Falls based lumber mill, producing glued-wood laminated products.
As a member of the Kaleden community, I have been involved in the Kaleden Volunteer Fire Department for 22 years, and also serve as a trustee on the Kaleden Irrigation District board.
I am currently married to my wife Judy, of 26 years. We are empty-nesters who enjoy living in Kaleden with our Welsh Terrier, Angus, and cat, Tibbs.
Our two daughters, Meagan and Hayley, reside in Richmond and Victoria, respectively.
