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.
A more comprehensive water level and flow data that includes current and historic water level, river flows, precipitation, and temperature are available through the Government of Canada's water office.
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 section.
