The Sooke Lake dam was raised in 2002 in order to end any capacity issues, but water restrictions have never been removed.

There has been a tunnel cored from the Leech River to Sooke Lake. It is unused to date though (and is sealed currently). ..........

.................

 

......Leech Watershed isn't anticipated to be a required source of CRD water for another 50+ years (and there are many who say it will never be needed). ...........

 

 

....A tunnel linking the Leech River to the Sooke Lake Reservoir was built in the 1980s in anticipation of water demands, but intake and outlet facilities have yet to be put in. ........

WTF?

why do you suggest carrying capacity is near max now on heavy demand says? never heard that suggested. just reservoir capacity.

While I don't know the specific circumstances in Victoria, I am a civil engineer and did spend my early career designing and constructing the major trunk mains, peaking reservoirs and pumping stations elsewhere

 

If I recall correctly the CRD has never installed a new trunk main from the reservoir other than replacing an existing one 15 years ago that was ending its service life.

Feb 24, 2019

Sooke: 100%
Goldstream: 57.8%
Total: 96%

But here’s something interesting. According to the stats, the average rainfall for feb is 191.8mm, but this feb only saw 55.2mm. Now you might wonder, how can we be at only 29% of the average rainfall? That’s because for whatever reason snowfall amounts are not recorded by the CRD for the purposes of recording precipitation.

Nevertheless, 2018-2019 has seen 106% of average cumulative rainfall to-date even without the snow.

One can’t help noticing that if our regional discussions about drinking water rely on CRD weather data, and precipitation is obviously the most critical data point when discussing the water supply, that not recording snowfall amounts as precipitation leaves a gaping hole that data? Despite nearly 70cm of snow having been recorded last month in Victoria and no doubt much more in the Sooke hills, the actual precipitation amount is at 29% of the average, and when viewed a year from now the conclusion will be that February was much drier than the average, not that the region experienced one of the heaviest snowfalls of the last decade.

You know for sure the CRD doesn't count snowfall as precip? That sounds very odd to me.


Life's a journey......so roll down the window and enjoy the breeze.

They only identify precipitation as rainfall, hence the reading of less than 60mm for the month (through Feb 24th).

The Sooke hills likely had a meter, or more, of snow last month.

We didn’t get a lot of rain and divide the snowfall by 10 -15 to get the precipitation and that might be the number?

Environment Canada says the Victoria International Airport weather station recorded 96.1mm of precipitation, 25.7mm of which was from rain and 68.5mm from snow.

 

The Sooke Hills tend to have significantly higher amounts of rainfall, so the 55.2mm number from the CRD makes sense but even then it's far below 96.1mm as recorded at the airport.
