Canadian River Water Quantity Status and Trends, 2009-2023

The Canadian Environmental Sustainability Indicators program provides a national summary of annual water quantity status in rivers across Canada from 2009 to 2023. It also offers trends assessing significant changes in water quantity, including very-high and very-low flows, at monitoring stations over a 50-year period from 1974 to 2023. Data is provided by Environment and Climate Change Canada in formats including CSV, GeoJSON, and interactive maps.

Use Cases

• Assessing annual water quantity status for Canadian rivers based on national summary data from 2009-2023.
• Analyzing long-term trends in very-high and very-low river flows based on 50-year monitoring station data.
• Mapping spatial patterns of water quantity across Canada using the provided geospatial data formats.
• Modeling hydrological changes and climate impacts using the indicator's calculated metrics and station-level data.

Strengths

• Includes a 50-year trend analysis period from 1974 to 2023.
• Provides data at both national summary and individual monitoring station levels.
• Offers multiple access formats including CSV, GeoJSON, and interactive visualizations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic or temporal bias inherent to the monitoring station network.
