The international board that controls the amount of water leaving Lake Ontario will reduce the outflow at midnight Saturday.
Even though the water level that caused erosion and flooding along the lakeshore this year are falling fast, Lake Ontario remains unusually high for this time of year, the International Lake Ontario-St. Lawrence River Board said.
However, the lake water level fell 13.8 inches in August, the biggest drop for that month in 99 years of record-keeping, and stands 27.6 inches below this spring's peak.
The board set this week's outflow at 2.43 million gallons per second, but as of Saturday that figure will be reduced to 2.36 million gallons per second. In June, the outflows reached almost 2.75 million gallons per second.
