Strong Winds Cause Water Levels to Drop in Western Lake Erie

The recent weather phenomena affecting the Great Lakes have garnered attention due to their significant impact on Lake Erie. Strong winds have caused a notable decrease in water levels in the western basin of Lake Erie, leading to concerns among local navigational interests.

Impact of Strong Winds on Lake Erie Water Levels

A major cold front has swept into the Great Lakes region, bringing heavy snowfall, high winds, and gale warnings. Meteorologist David Marsalek from the National Weather Service in Cleveland noted that this cold front is one of the most powerful events in recent memory.

Wind speeds reached 35 to 40 knots (40 to 46 mph) from the southwest.
The strong winds are pushing water away from the western basin, leading to reduced water levels.
A low water advisory has been issued for western Lake Erie, effective until 4 a.m. on November 28.

Significance of Water Level Changes

Port Clinton, Ohio’s Jet Express Ferry service reported significant water recession via photos on social media. Areas that were previously submerged are now exposed, revealing extensive stretches of wet sand.

As the water is displaced, the eastern basin of the lake is experiencing increased water levels due to storm surge, with forecasts predicting wave heights of up to 24 feet. These fluctuations in water levels are essential considerations for local mariners.

Scientific Insights on Water Displacement

Water displacement plays a critical role in understanding these changes. Professor Jay Austin of the University of Minnesota-Duluth emphasizes that shallow lakes, like Erie, are more susceptible to these events compared to deeper lakes.

When significant wind pushes water from one area of an enclosed body to another, it can sometimes generate a phenomenon known as a seiche. Though historically, lake conditions have led to severe incidents, such as the rogue wave on Lake Michigan in 1954, Marsalek does not predict such an event occurring with the current weather patterns.

According to Marsalek, the wind conditions are expected to change, which will gradually restore water levels in the western basin of Lake Erie over time. Observing these weather patterns is crucial for both navigation and regional safety.
