Reservoir Levels and Water Use

Note: ​Data from 2015 is included, to show impact of extreme dry weather con​ditions on total source storage.​​

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.

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.​​​​​​​​

Note: 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.​​
