Using a mathematical analysis, researcher David Seekell, at Umeå University in Sweden, and his American collaborators now suggest that the mean depth of lakes is 30 per cent lower than previously estimated. If we poured the water of all lakes on Earth together into one big lake, the mean depth of the lake would be 42 metres. Satellites can measure the volume of very large lakes, such as for instance Lake Vättern in Sweden or Lake Superior in the United States and Canada, but measuring the tens of millions of small lakes spread across the surface of Earth requires time-consuming field work. So far, there have been few estimates of the volume of fresh water in lakes on Earth, and those that exist vary greatly and are typically presented without any data or methods. "We were able to use the model to estimate the mean volume of lakes at each given lake surface area, but also for variations in volume of lakes with the same surface area.
Water is a key element for our survival we need to it live and make our crops grow. Lakes are bodies of water that are very important to our eco system. Without lakes certain cities would have no water source. Lake are also homes to a lot of endangered species. We need to think of better ways to help out lakes from becoming so scarce.
