Rivers and Streams - Flood Outlook Statement

 

Date: July 14, 2020

Time: 5:15 p.m.

This statement is in effect until July 17, 2020

 

The Sault Ste. Marie Region Conservation Authority is issuing 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.

An area of heavy showers and thunderstorms crossing Lake Superior will begin tonight. Rainfall and thunderstorms moving across the region may give local amounts of 20 to 40 millimetres tonight into early Wednesday morning.

Currently, local rivers, creeks, and streams are flowing at normal levels. Should the forecasted rainfall materialize, it will cause levels and flows to rise across the watershed. There may be localized flooding of low-lying areas and 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 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: July 15, 2020

Time: 11:00 a.m.

This statement is in effect until (or updated before) August 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 near average or drier than average in June. As a result, water levels did not rise as much as they typically do in June. Nonetheless, water levels are expected to remain high over at least the next few months and further record-highs are possible if wet conditions return.

Currently, Lake Superior water level is approximately 183.72 m IGLD85. Lake Superior rose 5 cm over the course of the month, while on average the water level rises 8 cm in June. At the beginning of July, Lake Superior was 13 cm below the record-high beginning-of-month level set last year in 2019. The level is currently 23 cm above average (1918-2019). 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 will continue to monitor Lake Superior wind conditions and lake levels closely.
