The International Lake Ontario – St. Lawrence River Board (Board) announced today that, in directing Lake Ontario outflows, it has been given the ability to continue deviating from the flow specified by Plan 2014.

Water levels on Lake Ontario have begun to decline more rapidly in recent days due to a combination of continued record-high outflows, declining inflows from Lake Erie and generally drier weather across the basin.
Lake Ontario water levels continue to decline slowly as the Board is maintaining record outflows of 10,400 m3/s (367,270 cubic feet per second).
Water levels are declining throughout the system as warmer, drier weather and record Lake Ontario outflows of 10,400 m3/s (367,270 cubic feet per second) continue.
Water levels are expected to decline throughout the system this week as drier conditions are forecast and record Lake Ontario outflows of 10,400 m3/s (367,270 cubic feet per second) continue. At its meeting on June 28th, the Board reached consensus to maintain the current…
The Board is doing everything possible to provide all possible relief to Lake Ontario and upper St. Lawrence River residents, while considering impacts throughout the system.
