International Lake Ontario-St. Lawrence River Board

The Board will temporarily decrease outflows over the second weekend of October to raise Lake St. Lawrence levels significantly and provide a brief, final opportunity for residents of Lake St. Lawrence to remove their boats and other equipment prior to winter.

With summer nearing an end, the Board will adjust its outflow strategy and allow Lake St. Lawrence levels to decline to the normal navigation season minimum following the September long weekend. This decision will allow for slightly more water to be released from Lake Ontario during the fall.

A public Great Lakes water levels webinar hosted by the International Joint Commission's Lake Superior Board of Control, Lake Ontario-St. Lawrence River Board and Niagara Board of Control was held July 17.
