2023.07.18 Unplanned Outage at Ear Falls/Lac Seul Generating Stations

There has been an unplanned outage at the Ontario Power Generation (OPG) Ear Falls and Lac Seul generating stations, and outflow from Lac Seul has been reduced to 0 m3/s since 8am this morning, July 18, 2023. Hydro One and OPG are working to resolve the issue, but the duration of the outage is currently unknown.

The Lake of the Woods Control Board has directed OPG to ensure a minimum of 50 m3/s of outflow (via spill) by the end of the day, if the issue is not resolved by this evening.

Please contact the Lake of the Woods Secretariat at or 1-800-661-5922 if you have any concerns. We will provide another update once the issue is resolved.
