Weather reports are not what they used to be - the climate has certainly changed.

The heavy rains that we are experiencing, sometime in just pockets of the Region, create serious flood potential.

The old approach to weather is a thing of the past – all the weather people can do is issue notices and monitor what is taking place tightly and keep the first responders a phone call away.

Flood watch graphicThe latest information provided by the International Lake Ontario – St. Lawrence River Board (ILOSLRB) indicates that Lake Ontario reached a mean daily water level of 75.80 m on July 14th, declining just under 1cm per day during the preceding week.

The latest water level is 12 cm below this year’s peak level (recorded on June 15th), but remains 78 cm above average and continues to be a record level for this time of year. Record high outflows (equivalent to the peak releases during June to August of 2017) continue to be released to lower the lake level and provide some relief to shoreline stakeholders, while also considering the effects of higher flows on interests in the St. Lawrence River.

Lake Ontario levels are expected to continue to slowly decline in the coming days, with the resumption of drier conditions combined with the continuation of record-high outflows. Notwithstanding, water levels will remain elevated for the next several weeks and well into the summer months as record inflows from Lake Erie are expected to continue.

All shoreline areas should be considered dangerous during this time. Localized flooding combined with the potential for waves to overtop break walls and other shoreline structures continue to make these locations extremely dangerous. Conservation Halton is asking all residents to exercise caution around Lake Ontario shoreline areas and to alert children in your care of these imminent dangers.

This Flood Watch – Lake Ontario Shoreline message will remain in effect until July 31st. Conservation Halton will continue to monitor Lake Ontario wind conditions and lake levels closely and will either terminate this message or issue further updates as necessary.

The Conservation Authority has a Flood Duty Officer whose job it is to keep a close eye on what is taking place and ensure that the people who take care of us are in the loop.

    The thing is, we haven’t seen anything yet. As the planet continues to heat up and more energy accumulates and water evaporation increases, the storms we see now will be nothing. We will have extreme weather events all too frequently. It is going to get a lot worse.
