It is the freshest water you can get!




Climate- warm, sunny, cold, frozen, wet

Threats- pollution, sewage, landfill, creation of dams.

Solutions- penalties for polluting, fines, restrict the building of dams.

Rivers- Rivers and streams only cover 0.3% of earth’s surface. The rivers look like tiny little arteries from space

Lake- A lake is a large body of fresh water. Lakes often end rivers. Lakes can, also, be the source of rivers.

Fauna- Shellfish, fish, beavers, alligators, muskrats, turtles, migratory birds, frogs, snails, dragonflies, insects, bacteria, hippos, freshwater muscles, minnows, leeches, bears, trout.

Flora- Algae, hyacinth, Moss, Water lilies, Picklerweed plants, Cattails, and Sawgrass.

Land Features- Wetlands, lakes, rivers, streams, creeks, ponds, canal, bay,

Three different zones:



  • Topmost zone: The Littoral Zone is near the shore. It is very shallow and warm and has a diverse community.
  • The Limnetic Zone is near the surface and is well lit. This zone is surrounded by the Littoral Zone and is dominated by plankton
  • The colder and denser zone is called the Profundal Zone. The animals in this zone are heterotrophs and there is little light. Heterotrophs: Animals that eat dead organisms and use oxygen for cellular respiration.

Other Facts:
  • Lakes, ponds, rivers, and streams are freshwater habitats. So too are swamps, bogs, and marshes. Altogether, these ecosystems contain all the water in the world that is not frozen, essentially salt-free, and accessible to humans.
  • It amounts to precious little water, less than half a percent of the world's water supply. Yet it is vital to the survival of humans and a wide range of critters from dragonflies and piranhas to beavers and bullfrogs.
  • Freshwater habitats contain 12 percent of the world's known animals, including 40 percent of the fish species. Many insects, amphibians, and crustaceans (such as freshwater shrimp) are also found in freshwater habitats. And wetlands are rich with birds, offering them a place to breed, nest, and raise young, and a source of food and shelter during long migrations. Some waterfowl such as grebes never leave this habitat.
