Water Safety Statement - Storm Surge - Lake Ontario & St. Lawrence River
Cataraqui Conservation has issued a Shoreline Conditions Statement today due to forecasted storm surge and waves from elevated west winds for May 16 and 17, 2022.


Weather Situation
:

The Surface Water Monitoring Centre (SWMC) of the Ministry of Northern Development, Mines, Natural Resources & Forestry (NDMNRF) is forecasting increased water levels due to storm surge from sustained west winds.

Risks:

According to recent International Lake Ontario – St. Lawrence River Board (ILOSLRB) information, the water level on Lake Ontario is currently 17 cm above average for this time of year, and although subject to future weather conditions is thought to likely be at its seasonal peak.

The SWMC forecasted storm surge values for eastern Lake Ontario and upper St. Lawrence River for May 16 and 17 and higher waves might cause localized shoreline erosion and inundation of low-lying areas.

Cataraqui Conservation is urging residents to take care along the shoreline.
