KINGSTON – The Cataraqui Region Conservation Authority (CRCA) has extended the Flood Warning today for Lake Ontario and the St. Lawrence River as water levels remain at record highs.
Water levels on Lake Ontario and the upper St. Lawrence River have declined by about 22 cm since their peak at the end of May. Despite high outflows at the Cornwall dam, the decline has been slow due to frequent rainfall. The International Lake Ontario – St. Lawrence River Board has forecast that a slow, steady decline will continue into the fall. Shoreline flooding and erosion from high waves is still possible during storms and periods of strong winds.
The water level measured today at Kingston is currently 75.60 m, which is 0.4 m below the Lake Ontario 100-year flood elevation of 76.0 m. The current level of the St. Lawrence River measured at Brockville is 75.20 m. This is 0.6 m below the 100-year level of 75.8 metres in that area along the River.
Shoreline residents are reminded that any work near the water (e.g. placement of fill, armour stone, repairs to docks, etc.) will require a permit from the CRCA. Call our office or visit our website www.crca.ca for further information.
The CRCA is urging residents to take care along the shoreline and on the water as levels decline. Unsafe/unstable banks may exist due to recent erosion, high water and wave action has deposited debris along shorelines and beaches, and floating debris could cause hazardous conditions for boaters.
