Upcoming Gate Changes

0

The International Lake Superior Board of Control advises that the gate setting of the control structure at the head of the St. Marys Rapids will be reduced gradually to the equivalent of one-half gate open beginning this afternoon, Monday, November 28th, and ending tomorrow morning, Tuesday, November 29th. This will continue the gradual reduction of flows and water levels prior to winter and also accommodate underwater inspections of the international railway bridge piers.

The one-half gate equivalent setting will be achieved by partially opening Gates #7 to 10 to a setting of 20 centimetres (cm) each, and closing the remaining gates in the main rapids. There will be no change to the setting of Gate #1, which supplies a flow of about 15 cubic metres per second (m3/s) to the channel north of the Fishery Remedial Dike.

The gates of the control structure are typically set to the one-half gate equivalent setting at the beginning of December, and are maintained at this setting throughout the winter to aid in the establishment of stable ice conditions and reduce the risk of ice-related issues in the St. Marys River.

Mr. Jean-Francois Cantin is the Board Member for Canada. Brigadier General Mark Toy is the U.S. Board Member.
