The International Lake Superior Board of Control will be adjusting the gate setting of the control structure at the head of the St. Marys Rapids a number of times over the next two weeks. This is to allow for additional flow measurements to be conducted in the St. Marys Rapids and to accommodate underwater inspections of the international railway bridge piers, and will result in a gradual reduction in flows and water levels prior to winter.
The first of these gate adjustments will take place this Thursday, October 29th. The gate setting will be reduced from the current setting equivalent to approximately four gates open, to a setting of approximately three gates open. The three-gate equivalent setting will be achieved by partially lowering Gates #2 to #13 and #15 to a setting of 51 cm each. Gate #14 and #16 will remain closed, and there will be no change to the setting of Gate #1, which supplies a flow of about 15 m3/s to the channel north of the Fishery Remedial Dike.
Further updates will be provided next week, prior to the additional gate changes expected to occur on November 3rd, 4th and 5th. Anglers should continue to be cautious of the potentially hazardous flow and water level conditions in the St. Marys Rapids that will be experienced throughout the month.
Mr. Jaymie Gadal is the Board Member for Canada. Brigadier General Richard Kaiser is the U.S. Board Member.
