Comprehensive Analysis of Water Diversions in Great Lakes-St. Lawrence River Basin

The International Joint Commission (IJC) recently introduced the 2025 Report on Water Diversions and Uses, highlighting sustainable water management strategies in the Great Lakes-St. Lawrence River basin. This report, a collaborative effort between the United States and Canada, continues from prior evaluations and further outlines the states and provinces' collective responsibilities in maintaining water resources.

Background and Context

Since a directive back in 1999 from both the Canadian and U.S. governments, the IJC has committed to assessing how diversions and consumptive uses of water impact the basin. The foundational aim was to address and manage challenges over the shared resource responsibly. Notably, the previous report dated back to 2015, and this new release evaluates advancements made during that period, allowing for a comprehensive comparison.

Key Findings

The 2025 report elaborates on the progress achieved since the last assessment, particularly emphasizing the need for states to adhere to the Great Lakes-St. Lawrence River Basin Water Resources Compact. It also stresses the importance of enhancing engagement with Indigenous communities to secure broader participation in decision-making processes. The report advocates for a range of recommendations:

• - Clearer definitions of key terminologies to minimize ambiguity.
• - Acknowledgment and integration of Indigenous rights and knowledge in water management frameworks.
• - Enhanced transparency and collaboration among all stakeholders, aiming for a resilient and proactive approach to ensuring water quality and availability.

Environmental and Economic Pressures

Gerald Acker, the U.S. Co-Chair of the IJC, stated that as environmental and economic pressures evolve, the Compact and Agreement serve as vital tools. They are essential for building resilience in the basin, ensuring it can endure stresses while retaining ecological and economic benefits critical to millions. The focus is now on advancing monitoring capabilities and incorporating greater efficiencies and sustainability practices, particularly for large-scale water users.

Susan Chiblow, a Canadian appointee to the IJC, emphasized that integrating Indigenous knowledge along with Western scientific methods enhances the overall understanding of the basin's water resources, leading to more effective management. This collaborative approach is vital for sustainability and future resilience.

Public Engagement and Input

To gather diverse perspectives, the IJC considered opinions from governments, academic institutions, Native nations, non-governmental organizations, and the public. This wide-ranging feedback molded the report's recommendations and facilitates a more inclusive approach. A consultants’ report also provided additional insights, bolstering the recommendations proposed by the IJC.

Next Steps

Looking ahead, the IJC has planned a virtual public meeting scheduled for January 27, 2026, where they will present the report's findings and engage with various stakeholders, offering insights into how the IJC can further enhance its efforts in protecting these vital water resources. This meeting exemplifies the IJC's commitment to transparency and public involvement in water management discussions.

In conclusion, the 2025 Report signifies a critical step toward sustainable water management in the Great Lakes-St. Lawrence River basin. Its recommendations highlight the way forward, ensuring that all stakeholders are involved in preserving this invaluable resource for future generations.
