What role does the International Joint Commission play regarding Lake Ontario?

The International Joint Commission (IJC) plays a critical role in managing water levels in Lake Ontario. It was established by the Boundary Waters Treaty of 1909 between the United States and Canada. One of its primary responsibilities is to ensure that the interests of both nations are balanced when it comes to the regulation of water levels and flows on shared water bodies like Lake Ontario.

Specifically, the IJC conducts periodic reviews of the water levels and flow management strategies, which typically occur every five years. This allows the commission to assess the effectiveness of current practices, make necessary adjustments, and ensure that the needs and priorities of various stakeholders—such as municipalities, industries, and environmental interests—are adequately considered.

By regularly reviewing and adjusting the management of water levels, the IJC helps mitigate the risks of flooding, protect ecosystems, and support recreational and commercial activities in the lake area. This crucial oversight means that option focused on the IJC's role in reviewing water levels accurately reflects its responsibilities concerning Lake Ontario.
