This statement is in effect until (or updated before) September 13, 2021.
The Sault Ste. Marie Region Conservation Authority is issuing a flood outlook statement for the area residents regarding current watershed conditions. Flood forecasting and warning is part of the Conservation Authority’s provincially mandated responsibilities. This statement is sent out so that residents can be informed and aware.
The weather forecast indicates 30 to 50 mm of rain is expected by Wednesday afternoon. There is a risk of an additional 5 to 10 mm rainfall due to thunderstorms.
Currently, local rivers, creeks and streams are flowing at normal levels. Forecast rainfall could elevate the flows and levels considerably across the watershed. There may be localized flooding in areas with low drainage.
The flood control channels owned and maintained by the Sault Ste. Marie Region Conservation Authority are currently flowing at normal levels. The flood control channels will experience a rise in water levels. It is important to remember that the water in rivers, streams and channels will be fast flowing during and after the rainfall event.
The Sault Ste. Marie Region Conservation Authority will continue to closely monitor stream flows across the watershed and updates will be provided as required.
Residents and visitors are urged to stay away from the flood control channels and all waterways. Flows can be especially dangerous and stream banks can be slippery. Please keep children and pets away from waterways during this time.

The Sault Ste. Marie Region Conservation Authority (SSMRCA) is advising that Lake Superior's water level is above its long-term averages. Therefore, the risk of shoreline erosion, lakeshore flooding and coastal damages still remains.
Currently, the Lake Superior level is approximately 183.57 m IGLD85. This level is 8 cm above average (1918 - 2020), 16 cm below the level of a year ago, and 28 cm below the record-high level at this time in 2019. For additional reference, the SSMRCA shoreline flooding hazard level used for planning and development review is 184.2 m.
Lake Superior's water level typically rises in July. Depending on the weather and runoff conditions, Lake Superior may decline slightly or may rise by up to approximately 10 cm. SSMRCA advises all shoreline property owners to prepare for potential coastal impacts such as erosion, lakeshore flooding, crawl space and septic system inundation especially during periods of strong winds and high waves.
SSMRCA staff continue to monitor Lake Superior wind conditions and levels closely.
