Water level and flow at 2,155 ECCC hydrometric stations, one page per station with a daily-mean hydrograph. The Datamart keeps only about 30 days, so we archive daily to build our own history (since 2026-09-18).
Provisional real-time data from ECCC: not yet reviewed and subject to change. This site does not issue warnings; for flooding, check your province's official agency.
