The water level on Lake Ontario has dropped more than 2 feet since the spring.
That's according to the International Lake Ontario - St. Lawrence River Board, the group responsible for regulating water levels on the lake and river.
The board said Lake Ontario fell 13.8 inches over the past month, the greatest decline for the month of August since records began in 1918.
Lake Ontario is 27.6 inches below the peak level recorded earlier this spring.
Because the water is going down, the board will decrease the outflow of water from dams to balance the impacts to navigation and other interests in the upper St. Lawrence River.
The outflows will drop at midnight Saturday.
