The Nutrient Targets Regulation (M.R. 77/2024) under Manitoba’s Water Protection Act sets specific nutrient concentration and loading limits to protect Lake Winnipeg. It defines the lake’s north and south basins and the narrows between them. The regulation establishes maximum allowable concentrations of total phosphorus and total nitrogen for all three lake regions. It also sets annual nutrient loading targets for major tributary rivers flowing into the lake, including the Dauphin, Saskatchewan, Winnipeg, and Red Rivers, with the Red River having the highest limits due to its size and flow.
