Nutrient Concentrations in Great Lakes Tributaries, Focus on Lake Erie

Water quality monitoring data collected in priority tributaries to estimate nutrient loads to the Great Lakes. The dataset is provided by Environment and Climate Change Canada to advance science on recurrent toxic and nuisance algae. The majority of the data is focused on Lake Erie, the smallest and shallowest of the Great Lakes.

Use Cases

• Estimate nutrient loadings from Canadian tributaries based on concentration data.
• Model factors affecting tributary and nearshore water quality and ecosystem health.
• Support development of binational phosphorus objectives and load reduction targets.
• Analyze water quality issues in Lake Erie, described as most susceptible to nearshore problems.

Strengths

• Data is collected to support binational lake ecosystem objectives and management frameworks.
• Focus on Lake Erie provides specific insight into a region described as most susceptible to nearshore water quality issues.
• Last updated date is provided as 2026-05-05 18:02:08.662437.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to its collection from selected Canadian tributaries.
