Current Watershed Conditions

Rivers and Streams - Water Safety Statement

Date: April 26, 2021

Time: 12:30 p.m.

This statement is in effect until (or updated before) May 5, 2021.

The Sault Ste. Marie Region Conservation Authority is issuing a water safety statement for the local area watershed. 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 light to moderate rainfall for next five days. Total rainfall amounts are 30 to 45 mm plus 5 to 10 mm due to thunderstorms. Daytime high temperatures are forecast in the range of 6 to 13 degrees Celsius over the next five days.

Currently, local rivers, creeks and streams are flowing at normal levels. Forecasted rainfall and warm temperatures will cause levels and flows to rise across the watershed. There may be localized flooding in areas with poor 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 the channels will be cold and 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.

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.

 

 

Shoreline Conditions Statement - Lake Superior Flood Watch

  

Date: April 26, 2021

Time: 1:00 p.m.

This statement is in effect until (or updated before) May 25, 2021.

The Sault Ste. Marie Region Conservation Authority (SSMRCA) is advising that Lake Superior water levels remain above average, the risk of high-water impacts remains in effect.

Last month, Lake Superior declined 2 cm, while on average (1918 - 2020) it declines 1 cm in March. Water levels of Lake Superior appear to be near its seasonal low points and is expected to begin its seasonal rise. However, there will continue to be an increased risk of shoreline erosion, lakeshore flooding and coastal damages over the next several weeks and potentially throughout the spring.

Currently, the Lake Superior water level is approximately 183.42 m IGLD85. This level is 18 cm above the average (1918 - 2020), 18 cm below the level seen during the same time period in 2020 and 20 cm below its record-high level of 1986. For additional reference, the SSMRCA shoreline flooding hazard level used for planning and development review is 184.2 m.

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 lake levels closely.
