Reservoir Levels and Water Use


​STAGE 2 Water Restrictions​

Lawn Watering Prohibited as of August 4

Lawn watering prohibited

​​Metro Vancouver posts weekly storage levels for the Seymour, Capilano, and Coquitlam reservoirs from May to October. During the hot, dry summer months our daily water use can increase by 50% due to lawn watering and increased outdoor use. This increased regional water demand, combined with changes to snowpack and warmer annual temperatures due to climate change, could put a strain on the existing water supply.

Water conservation plays a key role in ensuring we will have enough drinking water today and for future generations.


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.

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.​​
