Are there environmental concerns or protections for Great Slave Lake?
Posted on Aug 25, 2025 / Travel
Yes—like many northern ecosystems, Great Slave Lake faces pressures from climate change, potential industrial development, and localized pollution that can affect water quality and traditional food sources. Thawing permafrost and changing ice regimes alter run-off, shorelines, and aquatic habitats, while any upstream mining or industrial activity raises concerns about contaminants entering the lake. The lake and surrounding lands are the subject of collaborative management involving territorial authorities, Indigenous governments, and environmental organizations to monitor water quality and safeguard fisheries. Many protection measures focus on sustainable fishing limits, monitoring pollutants, and assessing cumulative impacts from development. Visitors and operators are encouraged to follow Leave-No-Trace principles and support local stewardship initiatives to help preserve the lake for future generations.
