Dear Friend of Lake Ontario and the St. Lawrence River:

The International Lake Ontario-St. Lawrence River Study will release its final report on May 31, 2007. The report concludes five years of work involving more than 200 scientists, economists, planners and engineers from both Canada and the United States.

The Study's aim was review the water level and outflow regime, currently Regulation Plan 1958D with Deviations, and to involve the public in choices in that review. All interests were considered equally in considering options for regulation of the system, including: coastal; commercial navigation; domestic, industrial and municipal water uses; the environment; hydroelectric power; and recreational boating and tourism.

A Public Interest Advisory Group (PIAG) was composed of interested citizens who played a key role in the work of the Study from the outset. The two PIAG leads, one from the United States and one from Canada, were full Board members.

The International Joint Commission appointed the Study Board and Public Interest Advisory Group in 2000 to review its orders of approval regulating the levels and flows through the Moses-Saunders Dam at Cornwall.

On May 31, 2007, the U.S. and Canadian Study co-chairs will answer your questions in a media availability session at 10 a.m.

The number will be the same in both cases: 1-888….. passcode 1111

That same day, the public will be invited to participate in a streaming audio web conference to present an overview of the Study's findings. That will take place at:

You can also call in and participate with the option to the view the slides on-lines while doing so.
