International Joint Commission, Canada, United States, Annual Report, 2004, Great Lakes Water Quality Agreement, Watershed Initiative, Levels and Flows 

"The International Joint Commission prevents and resolves disputes between the United States of America and Canada under the 1909 Boundary Waters Treaty and pursues the common good of both countries as an independent and objective advisor to the two governments.

The International Joint Commission assists the two countries in the protection of the transboundary environment, including the implementation of the Great Lakes Water Quality Agreement and the improvement of transboundary air quality. It rules upon applications for approval of projects affecting the levels and flows of boundary or transboundary waters and may regulate the operation of these projects. In addition, the IJC apportions water and monitors water quality in certain transboundary watersheds, and alerts the governments to emerging issues along the boundary that may give rise to bilateral disputes."
