Rising water levels along Lake Ontario are prompting a shoreline conditions statement, with residents across Northumberland being urged to stay aware as levels continue to climb.
Quinte Conservation says water levels have reached approximately 75.30 metres this spring, driven by heavy rainfall and snowmelt. Levels have increased by about 0.76 metres since March, reaching a threshold that triggered the advisory.
Officials say water levels are expected to continue rising through May and into June, with forecasts suggesting a seasonal peak between 75.40 and 75.50 metres if average conditions continue.
While the current levels are notable, Quinte Conservation says they are not unusual, noting that similar or higher levels have occurred in about one third of years since 1960.
Forecasts also indicate that this year’s peak is expected to remain 20 to 40 centimetres below the record highs experienced in 2017 and 2019.
Despite that, officials warn that even moderately high water levels can pose risks, particularly when combined with strong winds. These conditions can lead to localized flooding in vulnerable shoreline areas.
Residents in low lying or flood prone areas are being advised to stay vigilant, monitor weather forecasts, and watch for changing water conditions.
Quinte Conservation says it will continue to monitor wind, wave activity, and water levels, and encourages residents to report any significant changes.
Additional information, including current water levels, is available through Quinte Conservation and the International Lake Ontario St Lawrence River Board websites.
The expiration for the Shoreline Conditions Statement released today (May 7, 2026) is on Thursday, May 28, 2026.
