Where did Lake Erie come from?

Like all of the Great Lakes, Lake Erie is basically a divot formed from a moving glacier and is relatively young — less than 4,000 years old — in its current configuration. Several native peoples lived on lake's shores, including the Erie tribe and the Iroquois.

How did the Great Lakes filled with water?

About 20,000 years ago, the climate warmed and the ice sheet retreated. Water from the melting glacier filled the basins , forming the Great Lakes.

How did the Great Lakes get so deep?

The Great Lakes were born when glaciers receded from this part of the world at the end of the last ice age. As the icy bulldozers went northward, they carved out deep troughs in the earth that later filled with water.

Is Lake Erie natural?

Is Lake Erie still a dead lake?

Although small in volume, Lake Erie is a thriving, productive environment. It has survived challenges brought about by pollution, over-fishing, eutrophication, invasive species and harmful algal blooms.

How deep is the deepest part in Lake Erie?

With a mean surface height of 570 feet (170 metres) above sea level, Erie has the smallest mean depth (62 feet) of the Great Lakes, and its deepest point is 210 feet. Because of its small size and shallow character, the lake has a comparatively short water-retention time of 2.6 years.

Why is Lake Erie so dirty?

Lake Erie's algae blooms are caused by runoff pollution. This type of pollution occurs when rainfall washes fertilizer and manure spread on large farm fields into streams that flow into Lake Erie. This fuels a bumper crop of algae each year that can make water toxic to fish, wildlife, and people.

Will the Great Lakes ever run dry?

Water levels are likely to decline somewhat in the next several months, as part of the usual seasonal cycle. But Gronewold cautions that soil moisture remains high in the upper lake basins, and he notes that even under dry conditions, it will be a couple years before the lakes would return to more typical levels.

Why are the Great Lakes 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.

What is wrong with Lake Erie?

Excessive algal growth in Lake Erie threatens the ecosystem and human health of a waterbody that provides drinking water for 12 million people in the U.S. and Canada. Algae can persist for weeks during summer by blooms carried by winds and currents eastward through the lake.

Are there underwater caves in Lake Erie?

Perry's Cave, registered as an Ohio Natural Landmark, is a natural limestone cave steeped in historical tradition. The cave lies 52 feet below the surface of South Bass Island in Lake Erie.

Why is Lake Erie water brown?
