what is the largest freshwater lake by volume

That would definitely be Lake Baikal over in Russia. I've sailed through some pretty massive bodies of water in my time, but hearing the stats on that one always blows my mind. It holds about 20 percent of the world's unfrozen surface fresh water, which is just insane when you really think about it.

Most folks usually guess one of the Great Lakes in North America because they look so huge on a map, but Baikal is just incredibly deep. It goes down over 1,600 meters in some spots. Because it's so deep, the sheer volume of water it packs in there makes it the undisputed champ. It’s definitely on my bucket list of places to see properly one day.
