Why is Lake Erie so productive?
Why is Lake Erie so productive? Lake Erie is the smallest of the Great Lakes by volume and also the shallowest. It warms quickly in the spring and summer and cools quickly in the fall. The shallowness of the basin and the warmer temperatures make it the most biologically productive of the Great Lakes.
Why is Lake Erie water so dirty?
The pollution process was exacerbated by water flowing into the lake from various industrial cities. Detroit was home to factories that dumped acids, iron and oil wastes into the river that flowed into Lake Erie at its Western end. Runoffs from Cleveland farms carried wastes into the lake from its Southern end.
Which Great Lake is cleanest?
Lake Superior is barely developed, compared to the other Great Lakes. This has allowed it to remain relatively undisturbed and free from much of the pollution and habitat destruction that the other lakes have suffered.
Why is Lake Erie so clean?
The major sources of phosphorus reductions were phosphorus outputs at wastewater plant discharges; eliminating phosphorous from laundry detergent; and no-till farming practices. Because of the phosphorus reductions, our Lake became much more clear and clean.
Is Lake Erie man made?
Lake Erie occupies a basin that was carved out of Earth's crust over millions of years by rivers and glaciers. The oldest rocks from which the basin was carved are about 400 million years old and formed in a tropical ocean reef environment.
Is Lake Erie ever calm?
While at times Lake Erie can be flat and calm, as wind blows across Lake Erie's surface, energy is transferred from the wind to the water. This energy generates currents and builds waves.
Why is Lake Erie so blue?
Cyanobacteria blooms (blue-green algae) are a frequent occurrence in the Great Lakes, particularly in Lake Erie, Green Bay, and Saginaw Bay. These blooms may cause fish kills and discolored or foul-smelling water, affecting both human and ecosystem health.
Why did the US want Lake Erie?

What 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.
Why is Lake Erie not salty?
The Great Lakes are not (noticeably) salty because water flows into them as well as out of them, carrying away the low concentrations of minerals in the water, writes Michael Moore of Toronto. Eventually, this water, with its small load of dissolved minerals or salts, reaches the sea.
Is Lake Erie shrinking?
In the first half of 2023, Lake Erie's water levels are expected to be lower than in 2022 by anywhere from 6 inches to 14 inches, according to predictions from the U.S. Army Corps of Engineers included in its December 2022 water level summary.
