With Lake Ontario water levels declining, Board adjusts outflow strategy
Lake Ontario levels peaked early this year at 75.40 m (247.38 ft.) on 5 May, 10 cm (4 inches) below the general flood stage and over a half meter (20 inches) lower than the peak in 2019. Lake levels are expected to continue their seasonal decline through summer, and have fallen 6 cm (2 in.) from the crest to date.
