  • Of the 15 deepest U.S. lakes, four are located in Alaska, and three are in Michigan.

There’s something 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.

There are plenty of deep lakes spread across the globe. 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.
