Conservation Halton Issues Flood Watch Statement for the Lake Ontario Shoreline


Conservation Halton has issued a flood watch statement for the Lake Ontario shoreline.

According to Conservation Halton, Lake Ontario has remained at its record daily lake level that it first reached on June 2. 

The latest daily mean water level of 75.90 m is the highest on record for Lake Ontario (higher than the greatest daily level observed in 2017) and is approximately 84 cm above the historical average for this time of year.  

However, further increases are expected.

Further increases in Lake Ontario outflows are expected as conditions downstream permit,” reads a recent news release. “Lake Ontario levels may continue to rise gradually over the next several days, but that the rise is likely to be small and highly dependent on precipitation inputs.”

A rise of no more than 5cm above the current record levels is expected, although, there is potential for a larger rise in levels under the wettest scenarios.

Regardless, with that being said, levels are expected to fall.

Lake Ontario is expected to reach its seasonal peak within the next one to three weeks before it begins to slowly decline,” notes the release.

However, according to Conservation Halton, levels will remain very high for the next several weeks and into the summer months.

All shoreline areas should be considered dangerous during this time.  

Localized flooding combined with the potential for waves to overtop breakwalls and other shoreline structures continue to make these locations extremely dangerous,” reads the release. “Conservation Halton is asking all residents to exercise caution around Lake Ontario shoreline areas and to alert children in your care of these imminent dangers.”

This Flood Watch - Lake Ontario Shoreline message will remain in effect until June 19.
