LRCA Flood Update – Lake Superior Shore

Flood Warning June 2 2019

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 September water level was 2 centimeters below the record high set in 1950. The level is currently 30 centimeters above average for September (1918-2018) and 18 centimeters higher than the level last year. The current water level is approximately 39 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 the fall and winter.

The main concern during high lake levels is shoreline erosion and flooding of low-lying shorelines including beaches and wetlands along the shore. Residents in shoreline and low-lying areas along Lake Superior should anticipate a prolonged period of above-average levels.

Authority Staff will continue to monitor conditions, and provide updates as necessary as part of its flood forecasting and warning program. Additional information can be found on the LRCA website

A Flood Watch is issued when there is potential for flooding. This Flood Watch will be in effect until terminated.
