The Convention on the Protection and Use of Transboundary Watercourses and International Lakes, established in 1992, is a significant international agreement aimed at promoting the sustainable management and protection of transboundary water resources. This convention specifically addresses the need for cooperation between countries that share watercourses and lakes, ensuring that these resources are used sustainably and conflicts are minimized. In the context of the United States, the convention governs all water that crosses into Canada, highlighting the importance of international collaboration in managing shared water resources.
