Unusually high levels of rainfall in the autumn led to the third wettest fall on record which created higher levels in Lake Ontario water levels, said joint U.S.-Canada regulators governing water levels. The International Lake Ontario-St. Lawrence River Board said in a statement, “Lake Ontario is currently 34 cm (13.4 inches) above the long-term average (1918-2020) and 34 cm (13.4 inches) below the record high set in 1945 for this time of the year. “In terms of total water supply to Lake Ontario, September through November 2021 was the third wettest fall on record. As a result, Lake Ontario experienced the third largest rise in water levels in October. The lake rose 8 cm (3.1 inches) as opposed to decreasing an average of 11 cm (4.3 inches) typically experienced that time of year.”
