Interesting Freshwater Biome Facts: Only 3% of the water on Earth comes from freshwater biomes. There are over 700 different species of fish that live in a freshwater biome. 99% of all freshwater is either in the form of ice or located in an aquifer. Many animals besides fish live in freshwater biomes.
There are three basic types of freshwater ecosystems: Lentic (slow moving water, including pools, ponds, and lakes), lotic (faster moving water, for example streams and rivers) and wetlands (areas where the soil is saturated or inundated for at least part of the time).
Freshwater is essential for our planet. … Healthy freshwater environments supply water for drinking, growing crops, manufacturing, energy and transport. They also help to prevent erosion, dispose of waste and provide natural protection from flooding. But we’ve been careless with this vital resource.
3% of the earth’s water is fresh. 2.5% of the earth’s fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth’s surface to be extracted at an affordable cost. 0.5% of the earth’s water is available fresh water.
Freshwater contains much less salt than the ocean. Most ponds, reservoirs, and rivers across North America are freshwater. Some common freshwater fish are bluegills, carp, catfish, crappie, bass, perch, northern pike, trout, and walleye. Many kinds of fish live in the salty water of the oceans.
Freshwater ecosystems account for less than 0.01% of the planet’s total surface area but they support more than 100,000 species, a list that includes more than just fish. Worms, mollusks, crayfish and insect larvae burrow into muddy lake or creek bottoms. Reeds and rushes along the shores shelter frogs and newts.

Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps.
Never drink water from a natural source that you haven’t purified, even if the water looks clean. Water in a stream, river or lake may look clean, but it can still be filled with bacteria, viruses, and parasites that can result in waterborne diseases, such as cryptosporidiosis or giardiasis.
These include drinking water, bathing, cooking, sanitation, and gardening.
However, the ecosystem of a freshwater lake or river can be extremely fragile, and human activities can be detrimental to their health in a number of ways: such as developing structures, diverting their flow, polluting them, and draining them of resources.
The Central Valley Aquifer in California underlies one of the nation’s most agriculturally productive regions, but it is in drastic decline and has lost about ten cubic miles of water in just four years.
While our planet as a whole may never run out of water, it’s important to remember that clean freshwater is not always available where and when humans need it. In fact, half of the world’s freshwater can be found in only six countries. … Also, every drop of water that we use continues through the water cycle.
The finding, published in Science, suggests that a reservoir of water is hidden in the Earth’s mantle, more than 400 miles below the surface. … It extends deep into the Earth’s interior as the oceanic crust subducts, or slides, under adjoining plates of crust and sinks into the mantle, carrying water with it. “
