While water quantity in the Lake of the Woods is largely gov
erned by a Canadian board, which is the Lake of the Woods Water Control Board, and sometimes the International Lake of the Woods Water Control Board if levels are too high or too low, this motion is about the lake's water quality for which there has been relatively little governance compared to other transboundary waters between Canada and the U.S. Currently, Ontario's Ministry of Natural Resources samples the lake annually and Ontario's Ministry of the Environment has also been involved in water quality monitoring and enforcement, but there has been a growing concern over conta

Bien que la qualité de l'eau du lac des Bois relève d'une commission canadienne, la Commission de contrôle du lac des Bois, et, lorsque les niveaux sont trop hauts ou trop bas, de la Commission internationale de contrôle du lac des Bois, la motion concerne la gestion de la qualité de l'eau, qui laisse à désirer comparativement à la gestion de la qualité de l'eau des autres plans d'eau à la frontière canado-américaine. En ce moment, le ministère des Richesses naturelles de l'Ontario prélève chaque année des échantillons de l'eau du lac.
