Something is haunting and mysterious about gazing into the blue expanse of a huge, ancient lake, and wondering what lies under the surface in the abyss below.

The ocean is one thing, but it’s unbelievable to think about just how deep the 15 deepest lakes in the United States can be.

Some have been created by glaciers or volcanoes, and some are remnants from the ice age millions of years ago.

From Russia’s famous Lake Baikal down to Lake Matano in Indonesia, these water-filled inland basins provide a home to thousands of ecosystems and offer rich water sources to millions of people around the globe. There are hundreds of thousands of natural and man-made lakes located in different states in the United States alone.

These lakes vary in surface area and depth, so which lakes do you think are the deepest in the United States? If you are looking to see or experience a deep lake, the good news is you won’t have to travel across continents to find one.

What is the Clearest Lake in the United States?

When it comes to bodies of water and categorizing them, finding which lake is the clearest is a difficult quality to measure; however, Lake Tahoe has been found to be the number one for clearest water! That may come as no surprise because of the lake’s reputation for being a resort destination.

When people think of Lake Tahoe they think of the ultimate lake for boating and fun on the water. It is no wonder that the area boasts well over three million tourists and visitors.

On top of its crystal clear qualities, Lake Tahoe also holds some of the absolutely most pure water to be found on the continent of North America. While the rest of the country struggles to reduce pollution and keep their bodies of water clean, Tahoe is mostly doing well.

Another very cool property of Lake Tahoe is that it holds a turquoise coloration, which comes from dissolved minerals within the waters!
