THUNDER BAY – The Lakehead Region Conservation Authority is continuing the Flood Watch for Lake Superior, within its area of jurisdiction.

The Lakehead Region Conservation Authority advises that water levels on Lake Superior continue to remain well above average. Record highs on Lake Superior were previously recorded in 1950, 1952, 1985, 1986, and 2019 with all-time lows recorded in 1925, 1926 and 2007.

The beginning of March water level was 4 centimeters below the record high set in 1986, 33 centimeters above average (1918-2019) and the same level as last year. The current water level is approximately 64 centimeters lower than the 100-year flood level for Lake Superior. Assuming average water supply conditions, Lake Superior is expected to continue its seasonal decline into March; however, it is expected to remain above average for a prolonged period of time.
