Where is the largest amount of freshwater found? - Quora.

The American Great Lakes account for 21 percent of the Earth’s surface fresh water. Lake Baikal in Russia is considered the deepest, oldest freshwater lake in the world. It holds about 20 percent of the Earth’s unfrozen surface fresh water, the largest volume in the world.This yield represents, the third largest renewable freshwater supply worldwide and the second largest amount per capita among developed countries—on average, 104,000 m 3 for every single Canadian. In term of water variability, the findings confirm that these yields vary greatly from year to year, by season, and across different regions of the country with the greatest yield framing coastal.Water is also highly visible in Canada: probably no country in the world has as much of its surface area covered by freshwater as does Canada. Of particular note are the Great Lakes. This set of lakes, which is shared with the United States, makes up the largest surface area of freshwater found in one place anywhere in the world.


Fresh water has low concentrations of dissolved solids and salts. Canada’s fresh water resources represent 7 percent of the world’s renewable fresh water. About 20 percent of the world’ fresh water is found in Canada, but less than half of it is considered renewable. Most of the fresh water is in the form of fossil water in glaciers.The Great Lakes cover a total surface area of 95,000 square miles and hold about 5,500 cubic miles of water (approximately 20% of all the world's fresh water and more than 80% of the fresh water of North America). There are more than 10,000 miles of shoreline that frame the Great Lakes and from west to east, the lakes span more than 750 miles.

Russia possesses one fifth of the world’s fresh water reserve but this water amount is rather unevenly distributed within Russia’s territory. Thus, the central and southern regions of European Russia, where 80% of the country’s population and industry is concentrated, have only 8 % of water resources (3).

The Amazon River flows through the center of the rainforest and is fed by 1,100 tributaries, seventeen of which are over 1,000 miles long. The Amazon is by far the largest river system in the world and over two-thirds of all the fresh water found on earth is in the Amazon basin's rivers, streams and tributaries.

A freshwater ecosystem can range from having lots of fast-flowing water to small amounts of stagnant water, and the kinds of animals found in the system change accordingly. Fish, mammals, reptiles, birds and insects are the most conspicuous types of animals native to freshwater habitats but there are many small animals such as crustaceans and molluscs that live there as well.

The Great Lakes are, from west to east: Superior, Michigan, Huron, Erie and Ontario.They are a dominant part of the physical and cultural heritage of North America. Shared with Canada and spanning more than 750 miles (1,200 kilometers) from west to east, these vast inland freshwater seas provide water for consumption, transportation, power, recreation and a host of other uses.

But how much accessible fresh water is there? Very little. Only 2.5% of all the water on Earth is fresh water and more than 97% is saltwater. Of this 2.5% of fresh water, more than two-thirds (68.7%) is frozen as snow and ice, and more than one-third is stored below ground as ground water.This means that only 0.3% of all fresh water on the planet is readily available as surface water in lakes.

Ninety-six percent of liquid fresh water can be found underground. Groundwater feeds springs and streams, supports wetlands, helps keep land surfaces stable, and is a critical water resource. About 60% of the water that is taken from the ground is used for farming in arid and semi-arid climates, and between 25% and 40% of the world’s drinking water comes from underground.

The combined area of the Great Lakes (some 94,250 square miles (244,106 square km)) represents the largest surface of fresh water in the world. The lakes—Superior, Michigan, Huron, Erie, and Ontario—are located in east-central North America and provide a natural border between Canada and the United.
