Columbia River Basin Long-term Water Quality Monitoring Data

Long-term freshwater quality monitoring data for over 13 sites in the Columbia River Basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change Canada (ECCC) and under the Canada-British Columbia Water Quality Monitoring Agreement to assess water quality status and long-term trends, detect emerging issues, establish water quality guidelines and track the effectiveness of remedial measures and regulatory decisions.
