Message:
A Colorado low will bring up to 25 – 40mm of rain to the area today and into this evening. Rainfall may be heavy at times, with locally higher amounts possible during thunderstorms. Local watersheds remain saturated from recent rain events and have limited ability to absorb more water, resulting in surface runoff. Depending on the intensity and amount of rainfall, small watercourses and urban drainage systems will fill up quickly and may result in localized flooding of low-lying areas. Larger rivers systems will respond, but we do not anticipate they will exceed normal spring runoff levels.
Grey Sauble Conservation Authority would like to remind everyone that significant runoff events can lead to unsafe conditions near rivers and streams. Fast moving water, slippery or unstable banks, and melting ice can present significant safety risks. Please stay alert and avoid watercourses when flows are high.
Grey Sauble staff will continue to monitor the weather and water levels and provide additional updates as needed.
Watershed residents can access snow, stream flow and rain gauge data through the Watershed Conditions page on our website: www.greysauble.on.ca/water-management/current-watershed-conditions/
This Statement expires Tuesday, April 7th, 2026 at 12:00pm unless replaced by further updates.
