CANCELLATION OF LAKE ONTARIO SHORELINE HAZARD WARNING

CANCELLATION OF LAKE ONTARIO SHORELINE HAZARD WARNING

Date:

Friday, August 23, 2019

Time:

10:00 AM

Issued To:

School boards, Municipalities, Local Conservation Authority, Local Police, Emergency services and media

Lake Ontario Water Level Conditions:

The shoreline hazard warning that has been in effect since April 30, 2019 is now cancelled as the static water level of Lake Ontario is below 75.5m as of August 23rd, 2019, at Toronto’s Fisheries and Oceans Canada tidal observation station.

The International Lake Ontario – St. Lawrence River Board (ILOSRB) is reporting that Lake Ontario water levels are expected to continue their seasonal decline through the remainder of the summer and into the fall, with the actual rate of decline largely depending on rainfall. However, with record inflows from Lake Erie expected to continue, water levels will remain near seasonal highs for at least the next several weeks.  Note that the ILOSRB has begun reducing outflows now that the lake wide average has also reached 75.5m.

Issues:

As static lake levels continue to recede along shoreline areas in TRCA’s jurisdiction, areas that had previously been under water will begin to become accessible again. However, the consistent inundation and flooding of these areas during the past four months will have weakened and eroded infrastructure such as boardwalks, trails and pathways, and therefore caution should still be taken in these impacted areas.

Actions:

Continue to stay away from areas that have been impacted by flooding and erosion and obey all trail closure notices. While the special Notice of Caution for the Scarborough Bluffs is no longer in effect, all signage must be obeyed, and the public is not permitted in areas that are not explicitly designated as public access areas. Please contact your local municipality 311 line for updated information on park and beach operations status.

For more information please contact the on-call Flood Duty Officer.
