Trend line for Metro Vancouver water supply: Big trouble ahead?

Water_levels_trend, CHW trend line to Oct, as of 28-June-2015

Trend line (pink) created by CityHallWatch showing a worst-case scenario from June to November 2015. Based on Metro Vancouver chart dated June 28. (Green, blue, and red lines are Metro Vancouver’s actual numbers for 2013, 2014, and 2015, respectively.)

From June to November each year, Metro Vancouver posts a graph online showing total reservoir storage levels. The information is updated each Tuesday. The latest date indicated is June 28.

As we await the next update, we at CityHallWatch tried to imagine where this is headed if we don’t receive some serious rainfall and if we keep consuming the same amount of water.

Water consumption is basically a straight line, with the slope of the line depending on the total average liters consumed per capita. A society that is better at conserving water will have a shallower slope for that pink line. Meanwhile the squiggles in 2013 and 2014 (green and blue lines) represent rainfall events recharging the reservoirs. How much rain will we get this year?

As parts of North America’s west coast area already in the grips of a mega drought that could last many years, how seriously are we and our governments taking the challenge of being water efficient?

  1. More important than oil.,Water resource will be even more scarce in the future. Govt needs to think carefully b4 selling any water💧or rights to water to any one

  2. Back home we grew up with water meters and limited water use was just a daily fact of life, wash your car, use a bucket, turn your front yard and back yard into produce gardens, water barrels, short showers and so on. Home water consumption was reflected in the bill we were sent. For those who rent here, when you or your neighbours are having showers till the hot water tank runs out everyone pays.
    Eroding salmon runs and other fishery stocks have been early predictors of what’s to come, a rainforest short of water. Eventually farmers will be forced to buy water to raise crops or animals further increasing the CPI.
    Instead of having a transit levy on our hydro bills to fund Translink how about a tax on water-based take-out consumer items like lattes and frappuccinos. If you can pay 3-4 bucks or more to stroke your ego you should buck up for water conservation, the cheapest coffee can be made at home.
