The Ganaraska Region Conservation Authority advises a series of low-pressure systems will continue to bring rainfall to the region over the next couple of days. Local watercourses are still experiencing higher than normal water levels and flows after receiving 40 to 55mm of rain on Tuesday, March 31st.
Flood Potential: Low
Issued: April 2, 2026 at 3:00 p.m.
Up to 10mm of rain is expected tonight, April 2nd, followed by another round of 15 to 20mm on Saturday, April 4th. Some snow cover still remains in the headwaters of our watersheds and with unseasonably warm temperatures on Friday and Saturday, melting snow will add runoff to local streams. Soils are generally saturated and will not have any capacity to absorb the runoff.
Streamflows are still declining after the heavy rainfall on Tuesday and are expected to increase as a result of the forecasted rainfall and snowmelt. While no flooding is currently anticipated, higher than normal water levels and flows will occur in local streams, ponds and ditches through the holiday weekend. In addition, slippery stream banks and fast flowing, cold water will create hazardous conditions around water bodies, especially in the vicinity of culverts and bridges. Please exercise caution around all water bodies and alert any children in your care of these hazards.
This Watershed Conditions Statement will be in effect until Monday, April 6th, 2026, at 12 p.m. Conservation Authority staff will continue to monitor watershed conditions and provide updates as necessary.
Note: A Watershed Condition Statement for Water Safety is issued as notice of the potential for high flows, unsafe banks, melting ice or other factors that could be dangerous for recreational users such as anglers, canoeists, hikers, children, pets, etc. Flooding is not expected.
