Concerns surface: Sooke Lake Reservoir fills a month later than normal

The reservoir, which contains 90 per cent of the CRD's water supply, filled nearly a month late this year

The CRD runs tours of the Sooke Lake Reservoir to educate and share information with citizens and students.

The Sooke Lake Reservoir is full, which is good news B次元官网网址 even if it is coming much later than usual.  

B次元官网网址淔or the last about 20 years we have tracked the reservoir levels from month to month, and usually the reservoir fills up by either early to late January,B次元官网网址 said Alicia Fraser, the Capital Regional DistrictB次元官网网址檚 general manager of infrastructure and water services.  

B次元官网网址淭hereB次元官网网址檚 been less than a handful of years whereby the end of January the reservoir hasnB次元官网网址檛 been filled.B次元官网网址 

This year the reservoir filled on Feb. 26, nearly a month later than usual.  

B次元官网网址淲e were quite a bit lower than we historically have been. We were starting to plan the measures that we would need to take, potentially looking at increasing our water conservation measures throughout the summer.B次元官网网址 

Each season the reservoir fills through the winter due to precipitation and runoff from surrounding water catchments.  

The late fill follows an exceptionally dry winter in B.C., as the Pacific region received less than 60 per cent of normal precipitation,

It's a trend that seems to be becoming more common. 

B次元官网网址淚n the last five years, this has become more frequent that we see the reservoir filling up later and later,B次元官网网址 said Fraser, with most of the reservoirs late fills coming during that time.  

B次元官网网址淭hree of those have been in the last five years and it is something that we are keeping a close eye on as we look at the changing climate.B次元官网网址 

The Sooke Lake Reservoir, located north of Sooke and west of the Malahat, has been the CRDB次元官网网址檚 primary source of drinking water since 1915 and makes up 90 per cent of the regionB次元官网网址檚 total water storage. It contains a total volume of 160.32 million cubic metres of water, with 92.7 million available for the water supply. In more visual terms, that is enough water to fill an Olympic swimming pool 37 times over.  

While the region is fortunate that heavy rains were able to bring the reservoir back to capacity, the late filling was cause for concern from the CRD, as Fraser says it was B次元官网网址済etting into the cautionary range, not that it was an imminent threat but it was lower than it had been in past years.B次元官网网址  

Fraser assured that while the late fills are B次元官网网址減robably not a good thingB次元官网网址 it's not a problem if it gets filled before consumption ramps up in the summertime.  

If the reservoir were not to be filled by that time, the CRD would need to implement new restrictions on water usage through the summer. Such restrictions could begin with increasing public water conservation before May 1, when restrictions typically begin.  

Following that, the CRD would have to consider implementing stage 2 or 3 restrictions, which would further restrict summer water use by reducing or prohibiting discretionary activities. These could include activities like washing driveways and sidewalks, along with more recreational activities like filling hot tubs and pools or even watering plants and gardens.  

A changing climate, along with increasing rates of development throughout the CRD, has prompted the water authority to revisit its strategic plan for water usage in the region, initially developed in 2017.  

B次元官网网址淭his plan focuses more on how we move forward with implementation, how we use pilot projects to look at changes in water quality, and how we move forward with these big infrastructure projects.B次元官网网址  

The plan to guide water usage through to 2055 is out for consultation. It does acknowledge that the Sooke Lake Reservoir likely cannot meet the region's water needs forever, with the earliest year the Leech Water Supply area may be needed to supplement the reservoir being in 2045.  

The CRD is inviting residents to give their input on the plan, through a survey that can be completed until March 31.
