Cataraqui Conservation has issued a Shoreline Conditions Statement today due to forecasted strong winds and resulting storm surge and high waves.


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 and wave heights.

Weather Situation:

A significant Colorado Low is forecast to move into the province over the next several days bringing high winds across the lower Great Lakes.


The SWMC forecasted storm surge values for eastern Lake Ontario on April 14 and 15 might be high enough to cause localized shoreline erosion and inundation of low-lying areas.

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

This Shoreline Conditions Statement will remain in effect until (or updated before) 11:59 PM April 16, 2022.
