Rivers and Streams - Flood Outlook Statement

 

Date: May 28, 2020

Time: 7:45 p.m.

This statement is in effect until June 3, 2020

 

The Sault Ste. Marie Region Conservation Authority would like to issue a Flood Outlook Statement to 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.

A low-pressure system will bring precipitation overnight across the watershed. Our area has already received 25-40 mm of rainfall. A further amount of 15-20 mm is forecasted overnight.

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.

The Sault Ste. Marie Region Conservation Authority would like to extend a warning to residents and visitors to use extreme caution when close to rivers, creeks and streams. High water levels and flows can be especially dangerous and stream banks can be slippery. Please keep children and pets away from fast flowing rivers and streams.

 
 
 
Shoreline Conditions Statement - Lake Superior Flood Outlook

 

Date: May 15, 2020

Time: 6:00 pm

This statement is in effect until (or updated before) June 15, 2020.

 

The Sault Ste. Marie Region Conservation Authority (SSMRCA) is advising that Lake Superior water levels remain well above normal. There are observations, reports, and expectations of shoreline erosion or flooding currently.

Conditions across Lake Superior were generally drier this past month and the water level rose less than it typically does in April. Nonetheless, an exceptional volume of water remains in the system and all the Great Lakes remain near or above record-high water levels for this time of year.

Currently Lake Superior water level is approximately 183.62 m IGLD85. Lake Superior rose 2 cm over the course of the month, while on average the water level rises 7 cm in April. For the beginning of May, Lake Superior is 12 cm below the record-high beginning-of-month level set in 1986. The level is currently 31 cm above average (1918-2019) and 7 cm below the level recorded at this time last year. 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 potentially severe coastal impacts such as significant erosion, lakeshore flooding and coastal damages, especially during periods of strong winds and high waves.

SSMRCA staff continue to monitor Lake Superior wind conditions and lake levels closely.
