Lake Erie conditions statement – high lake level outlook

Lake Erie Conditions Statement – High Lake Level Outlook
Haldimand Lakeshore and Grand River below Dunnville Dam

The following message issued by the Grand River Conservation Authority provides an update on the increased potential for lakeshore flooding and erosion along the Lake Erie shoreline.

Water levels remain near or above record highs in all of the Great Lakes, with the exception of Lake Ontario, which remains above average. As of August 9, Lake Erie’s level was 67 cm above the long-term average for this time of the year and 10 cm lower than the record-high set in 2019.

While the lake’s level has decreased slightly since May, there remains a heightened risk of shoreline flooding, beach submersion, crawl space and septic system inundation, as well as wave-driven erosion due to these near record-high static levels. This risk is expected to remain in place through the fall.

Local police and Haldimand County flood co-ordinators are advised that there is higher than normal potential for shoreline flooding and shore erosion through late 2020. The public is reminded to exercise caution around the shoreline, as well as nearby rivers and streams. Private land owners should prepare their properties as best as possible, and monitor shoreline erosion works on their properties. The higher than normal lake level coupled with wave action can impact and cause failure of shoreline erosion works.

Lake conditions and forecasts are being monitored closely and flood messages will be issued as necessary based on Lake level forecasts.
