Water levels are likely to decline somewhat in the next several months, as part of the usual seasonal cycle.

How long will Great Lakes last?

The sheer size of the individual Great Lakes means that pollutants can stay in the system for a long time: A water droplet or molecule of pollutant will reside in Lake Superior for as long as 191 years, Lake Michigan for 99 years, and Lake Huron for 22 years, whereas the smaller Lakes Ontario and Erie have residence ...

Not to worry: Niagara Falls still has at least around 20,000 years to be in production.

Will Lake Erie dry up?

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.

When engineers drained the Niagara Falls in 1969 they made a stomach churning discovery?

Engineers Who Drained Niagara Falls Made A Stomach-Churning Discovery Below. In the 1960s engineers closed the faucet at Niagara Falls – and found something shocking among the rocks. It's June 1969, and a team of engineers has succeeded in a Herculean task.

Did Niagara Falls freeze?

The only time Niagara Falls has technically frozen solid was on March 29, 1848, when Lake Erie froze and created an ice dam that prevented water from reaching the falls, according to World Atlas. It's a bit of a fluke that lives on as a special day in the natural wonder's history.
