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.
Currently, the Lake Superior water level is approximately 183.67 m IGLD85. Lake Superior rose 1.9 inches (5 cm) over the course of the month, while on average the water level rises 3.9 inches (10 cm) in May. At the beginning of June, Lake Superior was 5.9 inches (15 cm) below the record-high beginning-of-month level set last year in 2019. The level is currently 10.2 inches (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 high waves.
SSMRCA staff continue to monitor Lake Superior wind conditions and lake levels closely.
