Does Lake Erie have a dead zone?
Does Lake Erie have a dead zone? In Lake Erie, the hypoxic zone can be as large as 10,000 square kilometers and alters the lake ecosystem from July to October. These low oxygen areas are often referred to as “dead zones,” because many mobile organisms leave the hypoxic zone, and many sessile organisms die without adequate oxygen.
Can you swim in the dead zone?
Dead zones are not a direct threat to humans, but they are extremely harmful to fish, crabs, oysters, and other aquatic animals that humans rely on for seafood and livelihoods.
Does Lake Erie have an undertow?

The good news is that because Lake Erie is so shallow and turns over every 2.6 years, that it can get healthy pretty fast if the problem sources are reduced/eliminated.
What is unusual about Lake Erie?
Lake Erie is the second smallest Great Lake by surface area, and the smallest by volume. Because of this, the water of Lake Erie also has the shortest residence time. Water in this lake replaces itself every 2.6 years, as opposed to Lake Superior, which takes two centuries.
How big is the dead zone in Lake Erie?
In Lake Erie, the hypoxic zone can be as large as 10,000 square kilometers and alters the lake ecosystem from July to October. These low oxygen areas are often referred to as “dead zones,” because many mobile organisms leave the hypoxic zone, and many sessile organisms die without adequate oxygen.
How long will Lake Erie last?
Lake Erie has a lake retention time of 2.6 years, the shortest of all the Great Lakes. The lake's surface area is 9,910 square miles (25,667 km2). Lake Erie's water level fluctuates with the seasons as in the other Great Lakes.
Is Lake Erie still contaminated?
The water is drinkable and the amount of toxic chemicals has declined. “There's good news, but it is coupled with the sobering reality that we have significant problems that linger,” said Brian Smith, associate executive director of Citizens Campaign for the Environment.
