Seasonal water monitoring
Throughout the year, Metro Vancouver monitors source reservoir levels, snow pack, and other factors that affect the region’s water supply, including monitoring water use. Each factor is shown below and updated weekly during the high water use season, from May through October.
* Storage levels are updated Tuesday evenings. If Monday is a holiday, levels are updated Wednesdays.
** Based on measurements from the Orchid Lake Weather Station and the maximum average historical snowpack measured in April.
† Precipitation affects both supply and demand, but has a greater impact on demand during peak usage seasons
