Quinte Conservation is warning shoreline residents to be prepared for elevated water levels, strong waves and the potential for localized flooding along Lake Ontario and the Bay of Quinte through the weekend.
The conservation authority has issued a Shoreline Conditions Statement covering June 18 to June 20 as strong south and southwest winds are expected to affect the region.
According to Quinte Conservation, sustained winds of 40 to 60 kilometres per hour could generate a storm surge in the eastern end of Lake Ontario and the Bay of Quinte, with waves reaching between one and three metres in height.
Water levels along some sections of shoreline could exceed 75.6 metres, while forecasts suggest lake-wide levels may temporarily rise above 75.7 metres.
Officials say the combination of above-average lake levels and strong winds increases the risk of shoreline flooding, beach submersion, wave-driven erosion and flooding of low-lying areas, including crawl spaces and septic systems.
Quinte Conservation notes that Lake Ontario remains above seasonal average levels despite beginning its typical summer decline. Water levels peaked on May 29 at 75.49 metres and are expected to gradually decrease through the summer if average rainfall conditions continue.
The conservation authority says storm surge conditions and large waves can develop quickly with limited warning and is encouraging shoreline residents to remain vigilant and monitor weather forecasts and changing lake conditions.
Staff will continue monitoring wind, wave and water level conditions throughout the advisory period.
The shoreline conditions statement remains in effect until Monday, June 22, unless updated sooner.
Residents can find current water level information through Quinte Conservation and the International Lake Ontario–St. Lawrence River Board.
