NEWS RELEASE

MINISTRY OF NATURAL RESOURCES

************************

The Ministry of Natural Resources — Sault Ste. Marie/Blind River District is advising area residents that a flood warning is in effect for the district until Thursday, April 30, 2026, at 12 p.m.

Residents throughout the district should keep a close watch on water conditions and stay away from fast-moving rivers and streams. Parts of some watersheds within the district are currently experiencing flooding, including sections along the Blind River downstream from Duborne Lake and along the Potomac River.

Water levels are also high and rising along sections of the lower Mississagi, Thessalon, Bar, Chippewa and Goulais rivers. Water levels in area waterbodies are expected to rise further due to runoff from recent melting and forecasted rainfall events.

The ministry is closely monitoring the weather and developing watershed conditions. Further updates will be issued as appropriate.

TECHNICAL INFORMATION

Description of Weather System

Higher-than-average temperatures are forecast to prevail for the remainder of the week. Daytime temperatures will range between +8 to +17 C, with overnight temperatures of -1 to +6 C. Precipitation starting Friday night and into Saturday may bring 10-15 mm of rain. This pattern is expected to accelerate the rate of ongoing snowmelt and runoff.

Description of Current Conditions

Water levels and stream flows across the region are elevated from recent spring snowmelt and precipitation events. The remaining snowpack throughout the district remains significant, with measurements indicating depths averaging 50 cm and a snow water equivalent of 154 mm. These values are above the long-term average and increase the likelihood of above-normal runoff due to melting.

Risks in general may include fast-moving frigid water with rapidly changing conditions. Localized flooding in low-lying areas with a history of flooding is a possibility. A close watch on local forecasts and conditions is recommended.
