Top 10 largest water reservoirs

nature & geography

Water. We can’t do without it. It covers more than 70% of the Earth’s surface. The human body contains from 55% to 78% water. It’s suggested to drink around 6 glasses of water a day, around 2 liters. But water is also an important generator of energy. So what are the largest water reservoirs by volume?

The volume of all water on, in, and above the Earth, would be about 332,500,000 cubic miles (mi3) or 1,386,000,000 cubic kilometers (km3). The world’s oceans store the most water. Dams and reservoirs serve a number of different functions but one of the largest is to maintain an area’s water supply. Many of the world’s largest urban areas are supplied with water from rivers that are blocked via dams. But what are the largest water reservoirs by volume? Here’s a top 10 largest water reservoirs in cubic miles!
