Inflow to Lake of the Woods continues to rise and is expected to remain high over the next week. Another round of precipitation is forecast to impact the southern portion of the Winnpeg River basin at the end of the week and flows on the Rainy River are expected to increase.
To slow the rate of level rise on Lake of the Woods and achieve a gradual refill of the lake, staged outflow increases will continue with increases of 25 m3/s per day to minimize impacts downstream on the Winnipeg River. Authorized outflow will increase to 500 m3/s on April 19, to 525 m3/s on April 20 and to 550 m3/s on April 21.
Each of these outflow changes will cause levels along the Winnipeg River to increase by 6 cm (2 in) directly below the Norman Dam and by 3 cm (1 in) above the Dalles for a total rise of 20 cm (8 in) and 11 cm (4 in) respectively at each location by Friday. These flow changes will not affect the level at Minaki.
