Update Regarding Upcoming Gate Adjustments on Friday, October 11

The Board advises that on Friday October 11, Gates #9 through #13 will each be lowered to 38 cm open and Gates #14 and #15 will be closed. This is a modification to the gate adjustments noted in the October 3, 2024 news release (https://ijc.org/en/lsbc/update-lake-superior-outflows-and-expected-conditions-october-2024). There will be no change to total flow as this is just a change in gate configuration which will allow a safe environment for survey work this month.

The International Lake Superior Board of Control is responsible for managing the control works on the St. Marys River and regulating the outflow from Lake Superior into Lake Michigan-Huron. Under any outflow regulation plan, the ability to regulate the flow through the St. Marys River does not mean that full control of the water levels of Lake Superior and Lake Michigan-Huron is possible. This is because the major factors affecting water supply to the Great Lakes (i.e., precipitation, evaporation, and runoff) cannot be controlled, and are difficult to accurately predict. Outflow management cannot eliminate the risk of extreme water levels from occurring during periods of severe weather and water supply conditions.
