Reservoir Levels & Water Use

With a below-than-average snowpack for spring, we expect to reach “full pool” before summer arrives. Currently, both Metro Vancouver reservoirs are below full storage levels as we support the migration of juvenile salmon from Seymour Reservoir and slowly refill Capilano Reservoir to the maximum operating elevation.

Metro Vancouver posts weekly reservoir storage levels from May to October, when rainfall is lower, and the regional water demand can increase by 50%.

Importance of Water Conservation

Drinking water is a precious resource that must be managed and used wisely. Please do your part by using a little less water and not wasting it, so that we may continue to meet demand throughout the summer.

Visit WeLoveWater.ca for easy tips on how to conserve water both indoors and outdoors.

Lawn watering accounts for over half the drinking water used for summertime activities. Under region-wide regulations in effect May 1 through October 15, residential lawn watering is allowed one day per week at set times determined by address. Find allowed watering days and times for your home or business at Lawn Watering Regulations.

Regional Water Use Versus Precipitation

Rainfall refills the reservoirs during the winter and spring, but dry periods and higher water use in the summer lower the reservoirs' water levels – and our drinking water supply.

Precipitation and water use values reflect averaged 2003 to 2019 data. Precipitation values are collected from the Capilano Reservoir, and are significantly higher than urban sites in the region.
