Fresh water flows into the sea at a place called the river delta. Depending on the geography of the delta, over time, the waters mix and the composition of the delta water establishes its unique saline content.
The saline content of the delta is lower than the saline content of the sea and higher than the saline content of the river, which should be zero.
You can read more about river deltas, below.
It becomes a salt water lake.
If the salinity is more than a few tenths of a percent, fish will begin dying off and the water as it is will not be fit to drink.
It evaporates, and forms clouds. Clouds blow over land, and rain. Rain runs into rivers, which run into the lake.
A large stream of surface water is usually called a river. A river is freshwater and runs from high to low ground.

Lakes are open water, backwater would describe a tributary that supplies a lake or where it runs off into lower country.
Freshwater fish need regular water without salt, Marine fish need salt water. Marine fish are more colorful and interesting then freshwater fish but they are a lot harder to look after than freshwater fish. Saltwater fish need more water to swim in and are more fragile than freshwater fish.
