Document Type: Proceeding Paper

Part of: North American Water and Environment Congress & Destructive Water


During this century, the levels of two of the Great Lakes have been regulated; Lake Superior since 1921 and Lake Ontario since 1960. The regulation is directed by the International Joint Commission (JJC) which was established with the signing of the Boundary Waters Treaty of 1909 between the United States and Canada. The UC created the International Lake Superior and St. Lawrence River Boards of Control to develop regulation plans and to supervise operations at regulatory facilities for Lake Superior and Lake Ontario, respectively. The regulation of these lakes has provided benefits to the interests sharing these resources; particularly during extreme drought and high supply periods which is made possible through the international cooperation of agencies in both countries.
