Great Lakes Connecting Channels Water Quality and Sediment Monitoring Data

Environment and Climate Change Canada provides water quality and suspended sediment monitoring data from the Great Lakes connecting channels. The dataset includes the St. Marys River, St. Clair River, Detroit River, Niagara River, and St. Lawrence River. It is used to determine baseline status, long-term trends, spatial distributions, and the effectiveness of management actions.

Use Cases

• Analyze long-term water quality trends based on monitoring data mentioned in the description
• Assess spatial distribution of suspended sediment concentrations across connecting channels
• Evaluate the effectiveness of environmental management actions based on baseline status data
• Determine compliance with sediment quality objectives for the listed river systems

Strengths

• Data covers multiple major connecting channels of the Great Lakes, including the St. Marys, St. Clair, Detroit, Niagara, and St. Lawrence Rivers.
• Managed by Environment and Climate Change Canada, a governmental environmental authority.
