"Freshwater" doesn't necessarily mean "clean" water - it just means water that does not have a concentration of salt like sea water does. A stream can be muddy and still be freshwater. Or a river can be muddy and be freshwater, or saltwater, or a combination of both.
A small, flowing body of freshwater is called a stream. Streams may also be called a: brook, creek, bayou, rivulet, wash, or run.
A large stream of surface water is usually called a river. A river is freshwater and runs from high to low ground.
The particles bouncing along a stream bottom is called saltation. This process involves particles being lifted and transported by the flow of water, before being dropped or settling back to the stream bottom. Saltation is common in streams with moderate flow velocities and bed roughness.
Animals that live in a stream included freshwater mollusks, fish, and in the Amazon River, freshwater dolphins. Also, crayfish, trout, bass, clams, and freshwater mussels are found in streams. :)
The area where a freshwater river or stream enters the ocean is called an estuary. It is a coastal area of brackish water formed when freshwater enters the ocean.
Streams run into larger rivers.
Streams run into larger rivers.
These streams are called Currents. An example would be The Gulf Stream.

A smaller stream of freshwater that flows into a larger stream is called a "tributary." Tributaries contribute to the flow and water volume of the main river or stream they feed into, and they play an important role in the watershed ecosystem.
When two streams come together, it is called a confluence. At a confluence, the two streams merge to form a single stream.
Neither. Platypuses do not actually live in water at all. They live in burrows which they dig at the side of freshwater riverbanks, creek banks or edges of lakes and ponds. In Australia, streams are called "creeks".
