Shoreline Conditions Statement – Lake Superior Flood Outlook
Posted: Aug 20, 2020

Issued August 20, 2020@ 11:00 am


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 the Lake Superior were wetter than average in July. As a result, water levels rose on Lake Superior. Nonetheless, water levels are expected to remain high over at least the next few months and further record-highs are possible if wet patterns develop.

Currently, Lake Superior water level is approximately 183.88 m IGLD85. Lake Superior rose 7 cm over the course of the month, while on average the water level rises 5 cm in July. At the beginning of August, Lake Superior is 8 cm below the record-high beginning-of-month level set last year in 2019. The level is currently 26 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 storm surge.

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

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