Reservoir levels

Reservoir levels by region

What kind of information are you looking for?

Most links in each regional section provide basic, near-real-time reservoir level data, every two hours for the past 50 hours.

Links to data at wateroffice.gc.ca, however, offer customized data options that include historical (search by date) and precipitation and temperature data.

For table-formatted near real-time data from our reservoir systems including precipitation, air temperature, lake levels, stream levels/flows and snow water equivalents, see our regional hydrometeorologic data pages.
