Automated Fresh Water Quality Monitoring and Surveillance Data

Historical water quality data measured on a continuous basis at over 23 locations across Canada is included in this dataset. Most locations include hourly temperature, dissolved oxygen, pH, specific conductance and turbidity. Data are collected by Environment and Climate Change Canada (ECCC) and in partnership with other federal departments and provinces and territories to enable the detection of short-term water quality events, and to determine trends in water quality, especially at transboundary sites (or Federal waters) in support of Federal legislation and international agreements, or to report on the status of Government of Canada priority aquatic ecosystems.
