BURLINGTON, ON

Conservation Halton advises that Environment Canada has issued a Yellow Watch – Severe Thunderstorm alert across southwestern Ontario. Late this morning through early this evening, torrential downpours with local rainfall amounts in excess of 50 mm are possible. Although soil conditions are moderately dry within our jurisdiction, creek water levels remain mildly elevated from intense rainfall earlier this morning and would be expected to increase further with additional rainfall.

Conservation Halton advises that rain expected has the potential to flood the creeks.

Widespread flooding is not anticipated, however, fast flowing water and flooding of low-lying areas, natural floodplains, and areas with poor drainage may be expected.

Conservation Halton is asking all residents and children to keep a safe distance from all watercourses and structures such as bridges, culverts, and dams. Elevated water levels and fast flowing water, combined with slippery conditions along stream banks continue to make these locations extremely dangerous. Please alert children in your care of these imminent dangers.

 Conservation Halton will continue to monitor stream and weather conditions and will issue an update to this Watershed Conditions Statement – Water Safety message as conditions warrant.

This Watershed Conditions Statement – Water Safety will be in effect through Wednesday July 22, 2026.
